Document Summary

All innervated by femoral nerve; contribute to flexion at hip joint. Sartorius (cid:894)(cid:858)tailor(cid:859)s (cid:373)us(cid:272)le(cid:859)(cid:895: 2-joint muscles; functions at both joints, origin: asis. Insertion: medial surface of shaft of tibia (below tuberosity: action: flexion at the hip, flexion at the knee, lateral rotation of thigh, and (abduction of thigh, tailor(cid:859)s (cid:373)us(cid:272)le: (cid:272)o(cid:374)tri(cid:271)utes to sitti(cid:374)g (cid:272)ross-legged. Tensor fascia latae: origin: iliac crest (posterior to asis) Insertion: upon patella & through patellar ligament on to tibial tuberosity flexes thigh at hip. Insertion: patella (pulls through/covers patellar ligament: action: extend leg at knee. Articularis genus: origin: distal part of anterior femur surface. Insertion: upper part of synovial membrane of knee joint: action: draws synovial membrane upward as leg extends, not a major mover. Innervation: nerve to vastus intermedius (branch of femoral nerve) Innervation: l2-l4 ventral rami: ventral = motor aspects of nerves that emerge. Innervation: femoral nerve: sits above p. major (superior, origin: anteriolateral surface of t12-l1 (l2)
