Document Summary

Chapter 7 muscles of the lower limb. Muscles of the hip: hip flexors (iliopsoas) anterior pelvic girdle, lateral compartment posterior compartment (glutes, posterior compartment (glutes) Muscles of the thigh: anterior compartment (quads, medial compartment (hip adductors, posterior compartment (hamstrings) Muscles of the leg: anterior compartment, lateral compartment, posterior compartments (calves) In order to produce movement at a joint, need muscle to pass that joint. Ball and socket joint, wide range of movements. Insertion: femur (muscle bellies combine into one single muscle) combined insertion of the two muscles iliopsoas. Action: hip flexion (weight lifting, squatting thigh moves closer to pelvis, decrease angle) One of the largest and strongest muscles in body. Action: hip extension, lateral rotation (reverse squatting, increase angle) Pic is a zoomed in posterior view, found underneath gluteus maximus. Action: hip abduction (move thigh from midline), medial rot ation (turn thigh in)
