Document Summary
Anatomy: pelvic girdle and muscles of anterior thigh (jan. 19th) Flexion / extension (leg swing forward vs. leg swing backward) Pronation / supination (with lateral and medial rotation / paired) Adduction / abduction (toward vs. away from midline) Lateral vs. medial rotation (turning foot inward and outward) Describe the bony structures of the lower limb pelvic girdle, femur, tibia, fibula, and foot. Pelvic girdle attaches the lower limb to the spine. Upper body weight passes through the girdle to the lower limbs. Strongest ligaments in the body support the pelvic girdle as it attaches it to the axial skeleton. Consists of 2 hip bones and the sacrum. Each hip bone = coxal or pelvic bone. Pelvic bones are anterior and meet the sacrum which is posterior. Hip bone + coccyx + sacrum = pelvis. The pelvis in childhood is made of 3 separate bones: ilium, ischium, and pubis. In adults these bones fuse together, boundaries are indistinguishable.
