Prostate Anatomy Lobes

Lobes of the Prostate. The prostate is divided into several lobes. Anterior LobeProstate Anatomy Lobes The anterior lobe is used to describe the anterior portion of the gland lying in front of the urethra

The prostate is found as a male accessory gland in all placental mammals excepting edentates, martens, badgers and otters. The prostate glands of male marsupials are disseminate and proportionally larger than those of placental mammals. In some marsupial species, the size of the prostate gland changes seasonally Prostate Anatomy Lobes

The anatomy of the prostate is made up of three lobes: the central lobe and lobes on either side called the anterior lobes. The central lobe of the prostate is pyramid shaped and rests between the ejaculatory ducts and the urethra

On the anterior end of the prostate are the two lateral lobes, which are rounded and shaped like orange slices when viewed in a transverse section. The lateral lobes are the largest lobes and meet at the midline of the prostate. Posterior and medial to the lateral lobes is the much smaller anterior lobe, a triangle of fibromuscular tissue just

Prostate is a pyramidal shaped fibromuscular and glandular organ. It is an accessory sex gland in males. It becomes functionally active at the time of puberty and its secretions ( acid phosphatase, fibrinolysin, citric acid, protaglandins) form the bulk of seminal fluid

was composed of diverse lobes by analogy with laboratory animals [1, 7]. This concept became popular even though no distinct lobes can be seen in the human. Thereupon, McNeal established the current and most widely accepted concept of various zones rather than lobes of the prostate [8, 9, 10]. Prostate Anatomy Lobes

The anterior prostate lobes (AP), also known as “coagulating glands”, are translucent and bilaterally attached to the lesser curvature of the seminal vesicles, cranially with respect to the other prostate lobes

The prostate develops from epithelial outgrowths form the prostatic segment of the urethra that grows into the surrounding mesenchyme. This outgrowth and branching start at week 10 during embryo growth; by week 12, there are 5 groups of tubules that form the lobes of the prostate

Prostate Hyperplasia BPH less commonly occurs outside of the transition zone. • Small BPH nodule at R base at the central/peripheral zone border • Benign prostate hyperplasia (BPH) typically arises in the transition zone, distorts zonal anatomy, and can get very large (over 200 mL).

The prostate consists of a base, an apex, an anterior, a posterior and two lateral surfaces. The prostateis divided into several lobes: the anterior lobe, the median lobe, the lateral lobes (left and right lobes), and the posterior lobe Prostate Anatomy Lobes

Prostate Gland. To say that the continuation of the human species is heavily dependent on procreation is a gross understatement. This natural wonder is made possible as a result of primary and secondary sexual characteristics that develop at birth and during puberty, respectively

More recently, McNeal and colleagues conducted detailed studies of the normal and pathologic anatomyof the prostate and defined a concept of anatomic zones, rather than lobes, to describe the prostate. 70, 71 There are four major zones within the normal prostate: the peripheral zone (70% of glandular tissue), the central zone (20% of glandular

The prostate gland has a fibrous outer layer that contains several nerves and blood vessels. It is covered by the pelvic fascia which is known as the prostatic sheath. This makes up the prostatic capsule. The prostate gland has right and left lobes that are separated by a median isthmus of the prostate, also known as the anterior lobe

Within true pelvis between bladder neck (base of prostate) and urogenital diaphragm / levator ani muscle (apex of prostate) Apex contains some muscle fibers from urogenital diaphragm Seminal vesicles extend from posterior prostate to posterior surface of bladder Prostate Anatomy Lobes

This article discusses the anatomyof the prostate, the diagnosis of prostate cancer, and the role of different MR tech-niques in the detection and management of prostate cancer. Conclusion Imaging provides important information for the diagno-sis and management of prostate cancer
