Posterior Part of Male Urethra 3D

  • Description                                                     
    • * Lies in the pelvis proximal to corpus spongiosum and is acted upon by urogenital sphincter mechanisms and also acts as a conduit.
    • * Consists of preprostatic segment, prostatic segment, and membranous segment.

 

  • Preprostatic Part of Posterior Urethra:
    • * Extends almost vertically from bladder neck to verumontanum (superior aspect) in prostatic urethra.
    • * Is surrounded by proximal urethral sphincter mechanism.

 

  • Prostatic Part of Posterior Urethra:
    • * Tunnels through the substance of prostate closer to anterior than the posterior surface of gland.
    • * There is an elevation called verumontanum (colliculus seminalis) at about middle of urethral crest. It contains slit-like orifice of prostatic utricle.

 

  • Membranous Part of Posterior Urethra:
    • * Is shortest, least dilatable and with the exception of external orifice is the narrowest section of urethra.
    • * Descends with a ventral concavity from the prostate to bulb of penis, passing through the perineal membrane.
