Which part of the levator ani provides support to the prostate (levator prostatae)?
Which part of the levator ani provides support to the prostate (levator prostatae)?
Show Hint
Anterior fibres of pubococcygeus form the levator prostatae.
Updated On: Jun 24, 2026
- Pubococcygeus
- Ischiococcygeus
- Iliococcygeus
- None of the above
Show Solution
The Correct Option is A
Solution and Explanation
Step 1: Identify the muscle group. The pelvic floor sling is the levator ani, made of three named slips: pubococcygeus, iliococcygeus, and ischiococcygeus.
Step 2: Focus on which slip wraps the urogenital organs. Only the pubococcygeus reaches forward to the midline organs. Its front-most fibres curl around the prostate in the male, and this specialised cuff is named the levator prostatae - the direct muscular support of the gland.
Step 3: Note the female counterpart for confirmation - the same anterior pubococcygeus fibres become the sphincter vaginae, proving this slip is the one related to the pelvic organs.
Step 4: Eliminate the rest. Iliococcygeus runs to the anococcygeal raphe and coccyx, and ischiococcygeus (coccygeus) backs the floor posteriorly - neither contacts the prostate. The supporting part is therefore the pubococcygeus.
\[\boxed{\text{Pubococcygeus (forms levator prostatae)}}\]
