: : True/False
: : 1. The superficial transverse perineus muscle is within the ischiorectal fossa.
: Im gonna say false. Should make the border between urogenital triangle and anal triangle. Seems to be a gray area. Disagree. Border is line between ischial tuberosities. The area is mostly yellow due to fat.
: : 2. Muscles attaching to the perineal body include the external anal sphincter, deep transverse perineus, superficial transverse perineus, ischiocavernosus and bulbospongiosus.
: True Disagree. Ischiocavernosus?
: : 3. The puborectalis muscle circles the posterior wall of the anorectal junction within the pelvic cavity.
: True Disagree. Within the ischiorectal fossa.
: : 4. The sphincter urethra surrounds the membranous urethra and is innervated by nerves derived from the pelvic splanchnic nerves.
: True Disagree. Somatic. Deep branch perineal nerve from pudendal nerve.
: : 5. The inferior fascia of the pelvic diaphragm is also known as the perineal membrane.
: False, urogenital diaphragm? Agree. Almost got myself here.
: : 6. The anterior superior recess of the ischiorectal fossa is bounded laterally by the gluteus maximus.
: False, obturator internus and conjoint ramus Agree. Wow! Redeeming yourself.
: : 7. The corpora cavernosa of the clitoris meet at the body of the clitoris and then continue together at the angle of the clitoris.
: True? I do not know Disagree. Meet at angle. Redemption awry.
: : 8. The inferior rectal nerve branches from the pudendal nerve at the entrance to the pudendal canal.
: Correct Agree. Majority of the time. May evaginate the wall of the pudendal canal.
: : 9. The bulb of the vestibule and the bulb of the penis are compressed by the bulbospongiosus muscles.
: True, again not sure Agree. Nod doubt.
: : 10. The inferior fascia of the pelvic diaphragm provides superior and lateral borders to the anterior superior and posterior recesses of the ischiorectal fossa.
: False, superior is correct for both, for anterior superior lateral borders see #6, posterior recesses lateral border is glut max. Agree. Superior and medial borders. Obt intern and glut max for lateral.
