prostatic utricle(redirected from Utriculus prostaticus)
1. any small sac.
2. the larger of the two divisions of the membranous labyrinth of the inner ear.
prostatic utricle (urethral utricle) a small blind pouch in the substance of the prostate.
a minute pouch in the prostate that opens on the summit of the seminal colliculus; it is analogous to the uterus and vagina in the female, being the remains of the fused caudal ends of the paramesonephric ducts.
the part of the urethra in men that forms a cul-de-sac about 6 mm long behind the middle lobe of the prostate. It is composed of fibrous tissue, muscular fibers, and mucous membrane. Numerous small glands open on its inner surface. It is homologous with the uterus in women. Also called uterus masculinius. See also prostate.
