Re: Gluteal Region and the Ischio Rectal Fossa - Study Guide Part I

Comments:
: : 1. The spinal cord ends at the vertebral level of L2(3) whereas the spinal canal continues to the level of S2. : True : : 2. The sacrospinous ligament contributes the inferior border of the of the greater sciatic foramen. : True : : 3. The sacrotuberous ligament contributes the superior border of the greater sciatic foramen. : False...its the medial border of lesser sciatic foramen : : 4. The gluteus maximus muscle takes origin, in part, from the sacrotuberous ligament. : True : : 5. In addition to the iliotibial tract, the gluteus maximus muscle inserts onto the gluteal tuberosity of the femur. : False...iliotibial tract : : 6. The gluteus maximus muscle receives the inferior gluteal artery but not the inferior gluteal nerve. : False...all inferior gluts to glut max and post branch of sup glut a. : : 7. The gluteus maximus muscle receives the superior gluteal artery but not the superior gluteal nerve. : True...post branch of sup glut a. : : 8. When standing with just one lower extremity planted (on one foot), the gluteus medius stabilizes the pelvis to prevent excessive pelvic drop on the supported (swing phase) lower extremity. : True : : 9. The quadratus femoris muscle, by virtue of inserting onto the intertrochanteric line, is a medial rotator of the hip joint. : False...lateral rotator : : 10. The superior and inferior gemelli insert onto the trochanteric fossa by way of the obturator externus tendon. : False...greater trochanter by themselves : : 11. The superior gluteal artery, but not the superior gluteal nerve, enters the gluteus maximus muscle. : True...only post branch of sup glut a. : : 12. The pudendal nerve, as it crosses the posterior surface of the ischial spine, is accompanied by the the internal pudendal artery. : True : : 13. The posterior cutaneous nerve of the thigh, within the gluteal region is located immediately medial to the tibial portion of the sciatic nerve. : True : : 14. The sciatic nerve consists of a peroneal portion that innervates original dorsal musculature and a tibial portion that innervates original ventral musculature. : True : : 15. The lateral femoral cutaneous nerve contributes to the L2 and L3 dermatome. : True : : 16. The lateral femoral cutaneous nerve, by way of the lumbar plexus, receives contributions from the dorsal rami of spinal nerves L1 and L2. : False...L2/L3 : : 17. A region of numbness matching the distribution of the lateral femoral nerve indicates compression of the L2 spinal nerve (spend money on an MRI). : True...only need to impact atleast one of the origins?? I think?
