Although there are three arteries that supply the testis, the __ is the most important, and its ligation may result in testicular atrophy.
Although there are three arteries that supply the testis, the TESTICULAR ARTERY is the most important, and its ligation may result in testicular atrophy.
The testis, epididymis, vas, and seminal vesicles are innervated by the __, which is made up of afferent and efferent nerves.
The testis, epididymis, vas, and seminal vesicles are innervated by the AUTONOMIC SYSTEM, which is made up of afferent and efferent nerves.
The anatomic zones of the prostate include the __, which is the site of benign prostatic hyperplasia; the __, which contains the ejaculatory ducts (glands arising in this zone are thought to be derived from the wolffian duct, unlike the glands in the rest of the prostate); the __, which contains 70% of the glandular epithelium and where 70% of prostate cancers occur; and the __, which is made up of fibromuscular stroma.
The anatomic zones of the prostate include the TRANSITION ZONE, which is the site of benign prostatic hyperplasia; the CENTRAL ZONE, which contains the ejaculatory ducts (glands arising in this zone are thought to be derived from the wolffian duct, unlike the glands in the rest of the prostate); the PERIPHERAL ZONE, which contains 70% of the glandular epithelium and where 70% of prostate cancers occur; and the ANTERIOR ZONE, which is made up of fibromuscular stroma.
70% of the prostate is made up of __, and 30% is __.
70% of the prostate is made up of GLANDULAR TISSUE, and 30% is FIBROMUSCULAR TISSUE.
A permeable septum separates the __, one from the other, and allows for free communication between the vascular spaces of the corpora bodies.
A permeable septum separates the CORPORA CAVERNOSA, one from the other, and allows for free communication between the vascular spaces of the corpora bodies.
Scrotal lymphatics do not cross the midline and drain into the ipsilateral groin, unlike the __, where the lymphatics cross over, allowing drainage to either groin irrespective of the side of the lesion.
Scrotal lymphatics do not cross the midline and drain into the ipsilateral groin, unlike the PENIS, where the lymphatics cross over, allowing drainage to either groin irrespective of the side of the lesion.
The rete testis forms 12 to 20 efferent ductules and passes into the largest portion of epididymis, the __.
The rete testis forms 12 to 20 efferent ductules and passes into the largest portion of epididymis, the CAPUT.
The __ is composed of smooth muscle cells that pass through collagenous tissue.
The TUNICA ALBUGINEA is composed of smooth muscle cells that pass through collagenous tissue.
The __ branch of the genitofemoral nerve follows the spermatic cord through the inguinal canal, supplies the cremaster muscle, and supplies sensation to the anterior scrotum.
The GENITAL branch of the genitofemoral nerve follows the spermatic cord through the inguinal canal, supplies the cremaster muscle, and supplies sensation to the anterior scrotum.
There are extremely strong tight junctions between Sertoli cells, which provide an intracellular barrier that allows for__ in an immune-privileged site.
There are extremely strong tight junctions between Sertoli cells, which provide an intracellular barrier that allows for SPERMATOGENESIS in an immune-privileged site.
There IS/IS NO true prostatic capsule at the apex of the prostate.
There IS NO true prostatic capsule at the apex of the prostate.
The penis, scrotum, and perineum drain into the __.
The penis, scrotum, and perineum drain into the INGUINAL LYMPH NODES.
The urethral mucosa that traverses the glans penis is __.
The urethral mucosa that traverses the glans penis is SQUAMOUS EPITHELIUM.
