Document Summary

Lower limb (cont"d) (reading materials: chapter 11: pages 308-321, 327-328; chapter. To understand the primary function a muscle you need to know where the muscle comes from (origin) and where it is going to (insertion). (inferior/superior gluteal nerve, from sacral plexus l5-s5) Innervation? lesser trochanter, innervation: iliacus- lateral to psoas major, o= anterior surface of ilium, i, tendons blend in, contract- powerful flexors of thigh at hip joint. Compartments of the thigh: (move leg at knee joint) anterior (extend leg @ knee) , posterior (flex leg @ knee, extend thigh. @ hip) , medial (adduct thigh) anterior (extensors of the knee thus they move the leg): (all femoral nerve, from lumbar plexus l1-l5) T= tibialis posterior d= flexor digitorum longus a= artery n= nerve h= flexor halluces longus. Innervation: lumbar plexus- obturator nerve + femoral nerve sacral plexus- sciatic nerve + gluteal nerves (superior + inferior) sciatic nerve- common pereneal nerve + tibial nerve.
