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. Todd’s Cycl. Anat.

Pars prostatica urethra epithelium

Therefore, the male urethra is also called the urinary spermatic tube. It is divided into four sections whose names correspond to their anatomical position: Pars intramuralis; Pars prostatica; Pars The spongy urethra is the longest part of the male urethra, and is contained in the corpus spongiosum of the penis. It is about 15 cm long, and extends from the termination of the membranous portion to the external urethral orifice. Commencing below the inferior fascia of the urogenital diaphragm it passes forward and upward to the front of the pubic symphysis; and then, in the flaccid condition of the penis, it bends downward and forward. It is narrow, and of uniform size in the Se hela listan på kenhub.com The epithelium of the pars prostatica consists in a transitional epithelium and is thick in the proximal portion but becomes thinner distalwards. The connective tissue of the propria and the submucosa is arranged more loosely than in the preprostatic part above.

Histology of the Membranous Urethra . The second part of the male urethra is the membranous urethra. This is a short segment.

The urethra is relatively long in male dogs (10 to 35 cm) and varies widely in length and width proximal to the os penis to permit distention with voiding and ejaculation. 39 It is divided into three segments: the preprostatic and prostatic sections that lie within the pelvic canal and the cavernous or membranous urethra (pars spongiosa). 39 The preprostatic segment extends from the transitional epithelium empty urinary bladder: 1. pars prostatica 2. pars membranacea function extends length diameter 3 parts.

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 connective tissue of the propria and the submucosa is arranged more loosely than in the preprostatic part above. 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 sensory nerve supply of the urethra of dog is very notable in general, and in particular, most liberal in the pars prostatica but somewhat less so in the partes praeprostatica, membranacea and cavernosa.The sensory fibres entering the mucous membrane of the pars praeprostatica end in subepithelial and intraepithelial simple branched terminations in most cases but more rarely in capsulated

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 prostatic urethra is the part of the urethra that passes through the prostate. It is about 3-4 cm long and extends from the base of the bladder, just below the pre-prostatic urethra, to the membranous part of the urethra. The prostatic urethra is surrounded by the internal urethral sphincter near its middle part; it is widest in the middle.

Die Harnröhre (Urethra) verbindet die Harnblase mit der Außenwelt und ist beim Mann durch den Verlauf im Penis mit ca. 20 cm deutlich länger als bei der Frau (3–5 cm).

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.
