The distal segment of the human male urethra, in particular the fossa navicularis, was studied with light- and electron microscopy as well as by means of histochemical and immunocytochemical methods. The fossa navicularis of the urethra contains a circumscribed zone of extremely thick, non-keratinized stratified squamous epithelium composed of cells containing a large amount of glycogen. These

The prostatic portion (pars prostatica), the widest and most dilatable part of the canal, is about 3 cm. long, It runs almost vertically through the prostate from its base to its apex, lying nearer its anterior than its posterior surface; the form of the canal is spindle-shaped, being wider in the middle than at either extremity, and narrowest below, where it joins the membranous portion.

bulbourethralis Cowperi In contrast to the almost completely straight female urethra, the male urethra has two bends due to its insertion in the penis. For the same reason, there are three bottlenecks in their course. In the pars prostatica, the ducts of the prostate and seminal vesicles enter. From here, the male urethra is part of the reproductive system.

Zusammenfassung: Rastereleketronenmikroskopische Beobachtungen am Epithel der Pars prostatica der menschlichen Urethra. Die Pars prostatica der menschlichen Urethra wurde rasterelektro‐nenmikroskopisch untersucht. An der dorsalen Wand der Urethra sind der Colliculus semi‐nalis und die Öffnungen der Ductus ejaculatorii erkennbar. Der obere Anteil der Pars prostatica der Urethra zeigt ein typisches Übergangsepithel mit großen, oberflächlichen Zel‐len.

This portion of the urethra goes through the prostate gland. The prostatic urethra is lined by transitional epithelium. Histology of the Membranous Urethra . The second part of the male urethra is the membranous urethra.

The prostatic portion (pars prostatica) of urethra, the widest and most dilatable part of the canal, is about 3 cm. long.

For the same reason, there are three bottlenecks in their course. In the pars prostatica, the ducts of the prostate and seminal vesicles enter. From here, the male urethra is part of the reproductive system. The distal segment of the human male urethra, in particular the fossa navicularis, was studied with light- and electron microscopy as well as by means of histochemical and immunocytochemical methods. The fossa navicularis of the urethra contains a circumscribed zone of extremely thick, non-keratinized stratified squamous epithelium composed of cells containing a large amount of glycogen. These the prostatic part of the male urethra, about 2.5 cm in length, that traverses the prostate; it includes the seminal colliculus, and the ejaculatory and prostatic ducts open into it.

Overview of prostate BPH tomografia, histology, and pathology. The prostatic urethra, the widest and most dilatable part of the urethra canal, is about 3 cm long. The urothelium, also called the transitional epithelium, is the layer of cells that lines the inside of the kidneys, ureters, bladder, and urethra Lamina propria consisting of connective tissue Muscularis propria, the outer layer of muscle tissue Fatty connective tissue covering the outside of the bladder and separating it from other organs The pars praeprostatica is rich in mucous folds, the epithelium is of 3-5-rowed cylindrical or transitional type and the surrounding muscularis comprises three layers, being very well-developed. The pars prostatica is situated at the ventral side of the prostata stretched bilaterally, and the lumen is expanded bilaterally in the proximal portion. The prostatic portion (pars prostatica) of urethra, the widest and most dilatable part of the canal, is about 3 cm.

Pada bagian terminal dari ductus, epithelium biasanya berbentuk collumnar dengan warna cat yang lebih gelap sebelum akhirnya memasuki urethra pars prostat. Stroma fibromuscular yang merupakan bagian lain dari glandula prostat, terdiri dari serabut otot polos dan jaringan ikat yang bercampur bersama stroma dan terdistribusi pada glandula.

The bladder neck and prostatic urethra contain transitional epithelium, the spongy urethra is covered with stratified columnar epithelium, and the fossa navicularis is covered with squamous epithelium, which is designed to withstand the stresses of abrasion. In shape the prostate resembles a Spanish chestnut. Todd’s Cycl. Anat., IV, 146/1, 1847–9 Very little is known as to the uses of the prostatic body.

Epithelium is derived from the urogenital sinus which forms from the ventral portion of the endodermal cloaca after its division (Bostwick: Urologic Surgical Pathology, 3rd Edition, 2014) Urethral sphincter surrounds the urethra Extends from the bladder neck to the inferior fascia of the urogenital diaphragm (Int Urol Nephrol 2014;46:1469)

The wall of the urethra consists of mucosa with variable epithelium.
