LEARNING OBJECTIVES

Foot 1. Demonstrate the relationship of extrinsic foot muscles to nerves and vessels of the foot. 2. Identify the groups of bones of the foot. 3. Understand the function of intrinsic foot muscles. 4. Define the arches of the foot and understand how each is maintained. 5. Define the role of the plantar aponeurosis. 6. Identify the retinacula of the ankle region. 7. Describe the sensory innervation for the foot.
