: Gluteal Region and Ischiorectal Fossa
: 1. Discuss the difference between the intertrochanteric crest and intertrochanteric line.
Crest is on posterior aspect of femur, line is on anterior aspect of femur.
: 2. What is the greater sciatic notch?
Bony margin of greater sciatic foramen, defined by medial concave contour of fused Ilium and ischium pelvic bones.
: 3. What is the lesser sciatic notch?
Bony margin of lesser sciatice foramen, defined by medial concave contour of pubic bone of the pelvis.
: 4. What is the greater sciatic foramen?
Medial margin is sacrospinous liagment, lateral margin is the greater sciatic notch; pass-through for Superior Gluteal Artery/Vein/Nerve, Inferior Gluteal Artery/Vein/Nerve, Sciatic Nerve, Posterior Femoral Cutaneous Nerve, Neve to Quadratus Femoris, Internal Pudendal Artery/Vein, Pudendal Nerve, Nerve to Obturator Internus.
: 5. What is the lesser sciatic foramen?
Medial margin is sacrotuberous ligament, lateral margin is lesser sciatic notch; pass-through for internal pudendal Artery/Vein, Pudendal Nerve, Nerve to Obturator Internus.
: 6. The spinal cord end at what vertebral level?
L2
: 7. The subarachnoid space (which contains cerebrospinal fluid) end at what level?
S2
: 8. Where (vertebral level) would you want to do a spinal tap - and where (vertebral level) would it endanger the spinal cord?
: 9. True or false: The iliac crest is on the same transverse plane as L4?
: L2 is at the same transverse plane as the posterior superior iliac spine?
: The ischial tuberosities are on the same transverse plane as the lesser trochanter of the femur?
: 10. What is the origin, insertion, innervation, and action of the gluteus maximus?
: 11. What is the origin, insertion, innervation, and action of the gluteus medius?
: 12. What is the origin, insertion, innervation, and action of the gluteus minimus?
: 13. What is the origin, insertion, and action of the superior gemellus?
: 14. What is the origin, insertion, and action of the inferior gemellus?
: 15. What is the origin, insertion, and action of the obturator internus?
: 16. What is the origin, insertion, innervation, and action of the tensor fascia lata?
: 17. What is the origin, insertion, and action of the quadratus femoris?
: 18. What is the origin, insertion, and action of the piriformis?
: 19. Discuss why the piriformis muscle is called the "gateway to the gluteal region and lower extremity".
: 20. What structures go through the greater sciatic foramen and enter into the lesser sciatic foramen?
: 21. What nerves are derived from the lumbar plexus?
: 22. What nerves are derived from the sacral plexus?
: 23. Discuss why an injection into the upper medial, lower medial, and lower lateral quadrants of the gluteal region would endanger certain structures.
: 24. Justify giving injections in the upper lateral region of the gluteal region.
