It extends downward and forward, with a slight anterior concavity, between the apex of the prostate and the bulb of the urethra, perforating the urogenital diaphragm about 2.5 cm. below and behind the pubic symphysis. Male Anatomy The prostate is an exocrine gland of the male mammalian reproductive system. ...
The urogenital diaphragm is an archaic term describing a layer of the pelvis separating deep perineal sac from the upper pelvis. ...
The pubic symphysis is the midline cartilaginous joint uniting the superior rami of the left and right pubic bones (pubis). ...
The hinder part of the urethral bulb lies in apposition with the inferior fascia of the urogenital diaphragm, but its upper portion diverges somewhat from this fascia: the anterior wall of the membranous urethra is thus prolonged for a short distance in front of the urogenital diaphragm; it measures about 2 cm. in length, while the posterior wall which is between the two fasciæ of the diaphragm is only 1.25 cm. long. Fascia is specialized connective tissue layer which surrounds muscles, bones, and joints, providing support and protection and giving structure to the body. ...
The membranous portion of the urethra is completely surrounded by the fibers of the Sphincter urethrae membranaceae. The Sphincter urethræ membranaceæ surrounds the whole length of the membranous portion of the urethra, and is enclosed in the fasciæ of the urogenital diaphragm. ...
In front of it the deep dorsal vein of the penis enters the pelvis between the transverse ligament of the pelvis and the arcuate pubic ligament; on either side near its termination are the bulbourethral glands. The pelvis (pl. ...
Male Anatomy In the anatomy of the male human body, the bulbourethral glands (or Cowpers glands) are two small, rounded, and somewhat lobulated bodies, of a yellow color, about the size of peas, placed behind and lateral to the membranous portion of the urethra, between the two layers of...
