Ankle and Foot Joints Complex
26 bones ~ 30 joints > 20 muscles
Simplification Tarsals Extrinsic muscles only 9 joints
Objectives 1. Be able to identify the bones of the ankle and
foot joints. 2. Be able to identify the joints of the ankle and
foot 3. Be able to identify the landmarks of the lower
tibia and lower fibula 4. Be able to identify and describe the
movements of the ankle and foot joints 5. Be able to identify and describe the general
attachments (distal/proximal), and movements of the ankle joint muscles
