Preferred Label : male urethral crest;
Uberon definition : narrow longitudinal fold of mucosa on the posterior wall of the male urethra, extending
from the uvula of the bladder through the prostatic urethra; when distended, it may
serve to prevent the passage of the semen backward into the bladder; on either side
of the male urethral crest is a slightly depressed fossa, the prostatic sinus, the
floor of which is perforated by the orifices of the prostatic ducts from the lateral
lobes of the prostate; the ducts of the middle lobe open behind the crest; at the
forepart of the crest, below its summit, is a median elevation, the colliculus seminalis,
upon or within the margins of which are the orifices of the prostatic utricle and
the slit-like openings of the ejaculatory ducts[MP];
