Basic Anatomy of the Foot
The foot is a flexible structures of bones, joints, muscles, and soft tissues that let us stand upright and perform activities like walking, running, and jumping. The foot is divided into three sections:
The forefoot contains the five toes (phalanges) and the five longer bones (metatarsals).
The midfoot is a pyramid-like collection of bones that form the arches of the feet. These include the three cuneiform bones, the cuboid bone, and the navicular bone.
The hindfoot forms the heel and ankle. The talus bone supports the leg bones (tibia and fibula), forming the ankle. The calcaneus (heel bone) is the largest bone in the foot.
Muscles, tendons, and ligaments run along the surfaces of the feet, allowing the complex movements needed for motion and balance. The Achilles tendon connects the heel to the calf muscle and is essential for running, jumping, and standing on the toes.
The foot is a perfect marriage of form and function. The foot contains 26 bones, 2 sesamoid bones, 33 joints, 19 muscles and 107 ligaments.
The skeletal system consists of bone, which is the hard substance that forms the framework of the body. Ligaments tie the bones together to form joints. Each bone and each joint has a name.
