1. The spinal cord ends at the vertebral level of L2(3) whereas the spinal canal continues to the level of S2.
2. The sacrospinous ligament contributes the superior border of the of the lesser sciatic foramen.
3. The sacrotuberous ligament contributes the superior border of the lesser sciatic foramen.
4. The gluteus maximus muscle takes insertion, in part, from the sacrotuberous ligament.
5. In addition to the iliotibial tract, the gluteus maximus muscle inserts onto the linea aspera.
6. The gluteus maximus muscle receives the inferior gluteal artery but not the inferior gluteal nerve.
7. The gluteus maximus muscle receives the superior gluteal artery but not the superior gluteal nerve.
8. When standing with just one lower extremity planted (on one foot), the gluteus medius is an adductor of the free (un-planted) lower extremity.
9. The quadratus femoris muscle, by virtue of inserting onto the intertrochanteric line, is a medial rotator of the hip joint.
10. The superior and inferior gemelli insert onto the trochanteric fossa by way of the obturator externus tendon.
11. The superior gluteal nerve, but not the superior gluteal artery, enter the gluteus maximus muscle.
12. The pudendal nerve, as it crosses the posterior surface of the ischial spine, is accompanied by the the external pudendal artery.
13. The posterior cutaneous nerve of the thigh, within the gluteal region is located immediately medial to the peroneal portion of the sciatic nerve.
14. The lumbar plexus, by way of the lumbosacral trunk, communicates (connects) with the sacral plexus.
15. The ventral ramus of the L5 spinal nerve does not contribute to the lumbar plexus.
16. The ventral ramus of the L4 spinal nerve contributes both to the lumbar plexus and to the sacral plexus.
17. The sciatic nerve consists of a peroneal portion that innervates original dorsal musculature and a tibial portion that innervates original ventral musculature.
18. The lateral femoral cutaneous nerve contributes to the L2, L3, and L4 dermatome.
19. The lateral femoral cutaneous nerve, by way of the lumbar plexus, receives contributions from the ventral rami of spinal nerves L1, L2, L3.
