Document Summary
The pelvic girdle and muscles of the anterior thigh: Review: understanding movements of the limbs: flexion / extension, pronation / supination. Inversion and eversion are more commonly used and similar to this function of the arm: adduction / abduction, lateral rotation / medial rotation, protraction / retraction, don"t really apply to the lower limb. Flexion differs from the hip and the knee joint. Pronation and supination can be applied as well but we often use inversion and eversion. Lateral and medial rotation of the lower limb: At the ankle joint: flexion decreases the angle is called dorsi flexion, and pointing down is plantar flexion. Eversion: bring lateral side out most weight for big toe (quite common when walking) Inversion: elevate the instep, most of the weight on the lateral side. Bony landmarks of the pelvic girdle: pelvic girdle is a complete ring (unlike pectoral girdle) and closed by the sacrum which articulates with the coccyx bones.
