  1. When describing the prostate's anatomy, it is divided into both zones and lobes. Your surgeon may refer to a specific zone, a specific lobe, or both when describing your surgery or diagnosis.
  2. The middle rectal and inferior vesical arteries arise from a common branch of the internal iliac artery. While the middle rectal artery only gives a few unnamed branches to the prostate, the inferior vesical artery gives a main branch to the urinary bladder and one to the prostate. The branch to the prostate then subdivides into two groups of arteries; one group primarily supplies the urethra and deep parts of the gland (urethral branches) while another group supplies the capsule and peripheral parts of the gland (capsular branches). The pudendal artery travels in the pudendal canal to supply the gland and other pelvic and reproductive structures.

A comprehensive cellular anatomy of normal human prostate is essential for solving the cellular origins of benign prostatic hyperplasia and prostate cancer Important to note is that many of the lymph vessels of the prostate anastomose with their counterparts of several neighbouring organs, for example of the urinary bladder and rectum. This can have important clinical implications, especially in cases of prostate cancer.The venous drainage of the prostate starts with the deep dorsal vein, which leaves the penis under the deep penile (Buck) fascia between the corpora cavernosa and then under the pubic arch. This vein then passes anterosuperior to the perineal membrane and divides into 3 major branches, the superficial branch and the right and left branches.the autonomic innervation reaches the prostate via the cavernous nerves and perforates together with the arterial branches the capsule of the prostate. The cavernous nerves run between the capsule of the prostate and the fascia of the levator ani muscle latero-posterior to the prostate.

The next layer is the central zone, which is approximately 25 percent of the prostate tissue. This area contains the ejaculatory ducts, which help move semen through the urethra and out of the body. The lymphatic drainage of the prostate primarily drains to the obturator and the internal iliac lymphatic channels. There is also lymphatic communication with the external iliac, presacral, and the para-aortic lymph nodes.Historically, the prostate has been divided into 3 zones: (1) transition zone, (2) central zone, and (3) peripheral zone. The transition zone accounts for 10% of the prostatic glandular tissue and 20% of the adenocarcinomas. The prostate consists of approximately 70% glandular tissue and 30% fibromuscular stroma.

A normal prostate gland is approximately 20 g in volume, 3 cm in length, 4 cm wide, and 2 cm in depth. As men get older, the prostate gland is variable in size secondary to benign prostatic hyperplasia. The gland is located posterior to the pubic symphysis, superior to the perineal membrane, inferior to the bladder, and anterior to the rectum (see the image below). The base of the prostate is in continuity with the bladder and the prostate ends at the apex before becoming the striated external urethral sphincter. The sphincter is a vertically oriented tubular sheath that surrounds the membranous urethra and prostate.

Capsular branches join the cavernous nerves posterolateral of the prostate and run to the pelvic floor. Small arteries branch off at right angle and perforate through the organ capsule.The sympathetic and parasympathetic fibers that come from the pelvic plexuses travel to the prostate via the cavernous nerves. The cavernous nerves run posterolateral to the prostate in the lateral prostatic fascia. Two thirds of the nerve fibers run along the traditional posterolateral aspect of the prostate; however, studies of the surgical anatomy of the prostate have demonstrated that the remaining third of the nerve fibers are more anterior in the anterior lateral aspect of the prostate. [2] This has resulted in the "Veil of Aphrodite" technique of nerve preservation to maximize the number of nerves preserved during radical prostatectomy. [3]  The parasympathetic nerves end at the acini and lead to prostatic secretion. The sympathetic nerves lead to contraction of the smooth muscle of the capsule and the stroma.

The hallmark histological feature of the prostate is the fibromuscular stroma in which there are clusters of smooth muscles mixed with elastic fibers. Surrounded by this mixture of tissue are prostatic glands, which are responsible for the production of approximately 27% of seminal fluid. These glands, under the directives of 5-α-dihydrotestosterone (DHT), secrete a watery mixture of prostate-specific antigen (PSA), prostatic acid phosphatase, fibrinolysin, and amylase into the prostatic sinuses (grooves lateral to the luminal aspect of the verumontanum).

The paired Cowper's glands lie laterally to the membranous portion of the urethra and open via a 2–5 cm long duct into the spongy urethra.Ejaculation is controlled by the sympathetic nervous system. The activation of prostatic alpha-receptors leads to the contraction of the smooth muscle stroma of the bladder neck; this causes the expulsion of the prostate gland content and closes the bladder neck for an antegrade ejaculation. Injury of the sympathetic nerves (e.g. due to retroperitoneal lymphadenectomy) leads to retrograde ejaculation. Prostate gland: This gland secretes prostate hormone.

The first arterial branch is the urethral artery that enters the prostatovesical junction posterolaterally and travels inward perpendicular to the urethra toward the bladder neck at approximately the 5 o'clock and 7 o'clock meridian. The urethral artery then turns caudally and parallel to the urethra to supply the transition zone. This artery is the main arterial supply for the adenomas in benign prostatic hyperplasia.The transitional zone is often described as having 2 lateral lobes and a median lobe that lead to the symptoms of the lower urinary tract symptoms. A urethral crest runs along the posterior midline and disappears at the membranous urethra. On both sides of the urethral crest, there is a grove where the prostatic sinuses exist and drain all of the glandular elements.

The anterior lobes of the prostate rest near the urethra. This tissue is non-glandular, meaning it does not secrete fluids. It is made up of muscle and fibrous tissue.

Surrounds the urethra just below the urinary bladder and can be felt during a rectal exam. Anatomy 24: Reproductive System. Authored by: Wendy Riggs The prostatic urethra runs through the prostate gland, dividing the prostate into a left and right lateral lobe. The paired ejaculatory duct perforates the prostate and opens into the middle of the prostatic urethra at the seminal colliculus (verumontanum). The prostatic utricle is a small indention at the seminal colliculus, it is a remain of the Müllerian duct. Usually the prostatic utricle is only 6 mm in size, but may be the reason for diverticula or cysts.

The transition zone (hatched area) surrounds the urethra between colliculus and bladder neck. The central zone (without shading) forms a funnel (sagittal plane) or ring-like zone (horizontal plane). The central zone is located between transition zone and peripheral zone. The ejaculatory ducts run through the central zone. The peripheral zone includes the peripheral sections of the prostate gland (dotted area). The prostate can be stimulated through the rectum. There are nerve endings throughout the entire rectum, but most people find that the prostate and the anus are the most pleasurable areas

As your respondents have mentioned women do not have prostate glands. One recent approach has been brought to light. Some women have claimed to have a G-Spot The glands are innervated by parasympathetic fibers of the pelvic splanchnic nerves by way of the prostatic plexus, which receives its fibers from the inferior hypogastric plexus (for erection and secretomotor of acini). The inferior hypogastric plexus also receives preganglionic sympathetic fibers from the superior hypogastric plexus to provide motor innervation to the smooth muscles of the stroma of the gland (for ejaculation and smooth muscle contraction).The prostate is surrounded by the puborectal portion of the levator ani. The seminal vesicles lie superior to the prostate under the base of the bladder and are approximately 6 cm in length. Each seminal vesicle joins its corresponding ductus deferens to form the ejaculatory duct before entering the prostate.

the inferior vesical artery approaches the prostate from laterodorsal and divides into urethral and capsular branches. The urethral branches perforate the basal prostate and bladder neck at 4 and 8 clock (view from lithotomy position) and supply the transition zone. Bleeding due to TURP or Adenomectomy are therefore expected at the bladder neck at the 4 and 8 clock position.The zone does not extend superiorly to the base of the gland; however, it continues inferiorly to form its distal part. The part of the prostatic urethra that is not enclosed within the peripheral zone is covered by the anterior fibromuscular stroma. The inferior muscle fibers of the anterior fibromuscular stroma are supported by striated muscles from the urethral sphincter below and superior fibers by detrusor muscle fibers from the urinary bladder above, all of which are mixed with connective tissue. The prostate is a fibroglandular organ which is involved in the production of semen. It is covered by a thin fibrous capsule, and is pierced by the urethra and ejaculatory ducts The arterial supply to the prostate is primarily from the inferior vesical artery, which originates from the anterior division of the internal iliac (hypogastric) artery. The inferior vesical artery then branches into 2 main arterial branches to feed the prostate. The prostatic vessels and the autonomic innervations run between the layers of the lateral prostatic fascia and the prostate. The inferior vesical artery supplies the base of the bladder, the distal ureters, and the prostate. Anatomy is the science of understanding the structure and the parts of living organisms. Physiology, on the other hand, deals with the internal mechanisms and the processes that work towards sustaining life

Indeed, PNI is highly prevalent in PCa, being reported in about 85% of radical prostatectomy cases [38, 39, 40] A laterodorsal pathway, which drains into the internal iliac nodes, via a course following the prostatic artery

The seminal vesicles produce an alkaline (pH 7.4) secret of gelatinous consistency, which contains fructose and forms half of the semen volume.The third component of continence is achieved by the levator ani. The major contributing muscles are the puborectalis complex. This complex forms the urogenital hiatus that flanks the sphincteric urethra. The active continence is controlled by the voluntary contraction of the levator ani musculature that surrounds the apex of the prostate and membranous urethra and the external urethral sphincter. The external urethral sphincter is a cylindrical structure that extends from the external surface of the prostate to the perineal membrane and consists of predominantly slow-twitch striated muscle. The internal sphincter is an extension of the circular smooth muscle of the vesicle neck that ends at the seminal colliculus.

The rectourethral muscle is a smooth muscle that lies posterior to the apex of the prostate. It rises from the rectum and inserts on the perineal body fat, thereby separating the urethra from the rectum (Brooks et al, 2001).Initially, a prostatic venous plexus lies between the true and false capsules of the gland. They subsequently drain to the prostatic venous plexus receives at the anterolateral part of the prostate gland. This plexus also receives deoxygenated blood from the deep dorsal vein of the penis and subsequently drains to the inferior vesical vein, which in turn drains to the internal iliac vein. Brachytherapy of prostate cancer involves permanent implantation of radioactive seeds in the prostate gland under transrectal ultrasound (TRUS) and fluoroscopic guidance with the goal to treat the entire..

National Kidney and Urologic Diseases Information Clearinghouse web site: “What I Need to Know About Prostate Problems.”The prostate is surrounded by a dense organ capsule. The prostatic capsule is not present at the apex (transition to the external sphincter) and at the basis (transition to the detrusor muscle of the bladder). Two puboprostatic ligaments fix the prostate to the pubic bone. The endopelvic fascia covers ventrally the prostate (visceral sheet). The endopelvic fascia (Fascia diaphragmatis pelvis superior) extends to both sides and covers the levator ani muscle (parietal sheet). The fold between visceral and parietal endopelvic fascia is called Arcus tendineus fascia pelvis. The cavernous nerves run in the parietal layer of the endopelvic fascia latero-dorsal to the prostate. The Denovilliers' fascia separates dorsal the prostate from the rectum.

Prostate is a fibromuscular glandular organ encompassing the prostatic urethra. It is pyramidal-shaped. The various secretions of the prostate gland comprise of acid phosphatase, fibrinolysin.. The anterior fibromuscular stroma, 5% of the prostate volume, is located anterior to the urethra and extends into the transition zone. The base is directed upward near the inferior surface of the bladder. The greater part of this surface is directly continuous with the bladder wall.The autonomic innervations of the prostate arise from the pelvic plexuses formed by the parasympathetic, visceral, efferent, and preganglionic fibers that arise from the sacral levels(S2-S4) and the sympathetic fibers from the thoracolumbar levels (L1-L2). The pelvic plexus is located beside the rectum approximately 7 cm from the anal verge, with its midpoint located at the level of the tips of the seminal vesicles.

(Note: Both the external and internal iliac nodes drain to the common iliac nodes, which subsequently drain into the right & left lumbar nodes)The majority of lymph drained from the anterior surface proceeds to the external iliac lymph nodes, via the paravesical space.A digital rectal examination allows the clinician to feel any nodular growth on the posterior surface of the gland. This is typically where prostatic adenocarcinomas can be palpated as these tumors most often arise in the peripheral zone.The arterial blood supply to the seminal vessels and ductus deferens comes from the deferential artery or artery of the ductus, a branch from the superior vesical artery.

The vasa deferentia (singular: vas deferens) bring sperm from the testes to the seminal vesicles. The seminal vesicles contribute fluid to semen during ejaculation.Our engaging videos, interactive quizzes, in-depth articles and HD atlas are here to get you top results faster. Prostate Anatomy. There are 4 basic anatomic zones of the prostate, as illustrated in Figure 1: the anterior zone, the peripheral zone, the central zone, and the transition zone 2. PROSTATE ANATOMY. The development of our present understanding was complicated by The concept of zonal anatomy of the prostate gland was first propose by McNeal (McNeal 1968) and is.. The gland is encapsulated by a true internal connective tissue capsule and a false external capsule, which is a continuation of the pelvic fascia. Its base sits at the neck of the urinary bladder, surrounding the proximal portion of the urethra. The urethra courses through the gland (known here as the prostatic urethra) and exits inferiorly at the apex.

The peripheral zone of the prostate constitutes 70% of the glandular tissue. This zone covers the posterior and lateral aspects of the prostate. The peripheral zone is the area that is palpated on digital rectal examination (DRE) and represents the area where 70% of adenocarcinomas are found. This area is also the location most commonly affected by chronic prostatitis.The prostate gland will be the accessory reproductive organ of focus for this article (for completion, the other two are the bulbourethral glands and the seminal vesicles). The gross and histological anatomy of this structure will be reviewed in addition to its neurovascular supply and some clinically relevant points.

The paired seminal vesicles are located behind the bladder and are each about 5 × 1 × 1 cm in size. Dorsal of the seminal vesicles is the rectum, lateral the ureter. The duct of the seminal vesicle opens into the ampulla of the ductus deferens Ampulla and forms the ejaculatory duct. See also anatomy of the epididymis and ductus deferens.The gland is supported anteriorly by the puboprostatic ligaments and inferiorly by the external urethral sphincter and perineal membrane. The puboprostatic ligaments are actually pubovesical ligaments; however, with the growth of the prostate from puberty, these ligaments have the appearance of terminating into the prostate.Alternatively, some vessels from the anterior lobe leave the prostate from the posterior surface, draining into the a group of nodes known as inferior gluteal lymph nodes, which are part of the internal iliac lymph nodes.
