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)

Todd’s Cycl. Anat. II, 459/1, 1836–9 Development of the prostate, seminal vesicles, and urethral sphincters Prostate The prostate is formed after differentiation of the urogenital sinus and the development… The female urethra is lined by stratified columnar epithelium, with a few small mucosal glands that secrete mucus, and is bound to the antierior wall of the vagina by an external layer of fibrous connective tissue. Zusammenfassung: Rastereleketronenmikroskopische Beobachtungen am Epithel der Pars prostatica der menschlichen Urethra.
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
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 .
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. long. 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.

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.
