Document Summary
Compression prevents bulging of muscles so force is transmitted over joint. Compression helps with venous return: continuous with inguinal ligament, pubic and membranous layer in inferior abdomen, becomes thicker on lateral side of thigh, with a lot of collagen fibers. This is known as the iliotibial tract (it band: distal attachment, cutaneous nerves, superiorly: Superior cluneal nerves (dpr l1-l3: medially, inferiorly (over gluteal fold): Posterior femoral cutaneous nerve (s2-s3) posterior gluteal line, posterior sacrum, coccyx, sacrotuberous. Superior gluteal nerve (l4-s1: proximal attachment: external surface of ilium, between anterior and inferior gluteal. Gluteus minimus lines: distal attachment, action: hip abduction and internal rotation anterior surface greater trochanter, works with gluteus medius, nerve innervation: Tensor fascia lata: proximal attachment, distal attachment, action: external surface of ilium, posterior to asis. Hip flexion, internal rotation, and flexion; assists in hip abduction: stabilizes the knee, nerve innervation:
