The foot is an anatomical structure found in many vertebrates. It is the terminal portion of a limb which bears weight and allows locomotion. In many animals with feet, the foot is a separate organ at the terminal part of the leg made up of one or more segments or bones, generally including claws and/or nails.

The leg is the entire lower limb of the human body, including the foot, thigh or sometimes even the hip or buttock region. The major bones of the leg are the femur, tibia, and adjacent fibula. The thigh is between the hip and knee, while the calf (rear) and shin (front) are between the knee and foot.
![<span class="mw-page-title-main">Cuboid bone</span> Bone of the ankle](https://upload.wikimedia.org/wikipedia/commons/thumb/1/18/Gray274.png/320px-Gray274.png)
In the human body, the cuboid bone is one of the seven tarsal bones of the foot.
![<span class="mw-page-title-main">Fibula</span> Leg bone in vertebrates](https://upload.wikimedia.org/wikipedia/commons/thumb/1/14/Fibula_-_anterior_view.png/320px-Fibula_-_anterior_view.png)
The fibula or calf bone is a leg bone on the lateral side of the tibia, to which it is connected above and below. It is the smaller of the two bones and, in proportion to its length, the most slender of all the long bones. Its upper extremity is small, placed toward the back of the head of the tibia, below the knee joint and excluded from the formation of this joint. Its lower extremity inclines a little forward, so as to be on a plane anterior to that of the upper end; it projects below the tibia and forms the lateral part of the ankle joint.
![<span class="mw-page-title-main">Ankle</span> Region where the foot and the leg meet](https://upload.wikimedia.org/wikipedia/commons/thumb/7/74/Ankle.jpg/320px-Ankle.jpg)
The ankle, the talocrural region or the jumping bone (informal) is the area where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot. In common usage, the term ankle refers exclusively to the ankle region. In medical terminology, "ankle" can refer broadly to the region or specifically to the talocrural joint.

The extensor hallucis longus muscle is a thin skeletal muscle, situated between the tibialis anterior and the extensor digitorum longus. It extends the big toe and dorsiflects the foot. It also assists with foot eversion and inversion.
![<span class="mw-page-title-main">Flexor hallucis longus muscle</span> One of the three deep muscles in the lower leg](https://upload.wikimedia.org/wikipedia/commons/thumb/9/96/Posterior_compartment_of_leg_-_flexor_hallucis_longus.png/320px-Posterior_compartment_of_leg_-_flexor_hallucis_longus.png)
The flexor hallucis longus muscle (FHL) attaches to the plantar surface of phalanx of the great toe and is responsible for flexing that toe. The FHL is one of the three deep muscles of the posterior compartment of the leg, the others being the flexor digitorum longus and the tibialis posterior. The tibialis posterior is the most powerful of these deep muscles. All three muscles are innervated by the tibial nerve which comprises half of the sciatic nerve.
![<span class="mw-page-title-main">Extensor digitorum longus muscle</span> Pennate muscle, situated at the lateral part of the front of the leg](https://upload.wikimedia.org/wikipedia/commons/thumb/5/5f/Gray1241.png/320px-Gray1241.png)
The extensor digitorum longus is a pennate muscle, situated at the lateral part of the front of the leg.
![<span class="mw-page-title-main">Fibularis brevis</span> Shorter and smaller of the fibularis (peroneus) muscles](https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Gray441.png/320px-Gray441.png)
In human anatomy, the fibularis brevis is a muscle that lies underneath the fibularis longus within the lateral compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to extend the foot downward away from the body at the ankle.
![<span class="mw-page-title-main">Fibularis tertius</span> Muscle of the human body located in the lower limb](https://upload.wikimedia.org/wikipedia/commons/thumb/2/2c/Peroneus_tertius_muscle_-_animation.gif/320px-Peroneus_tertius_muscle_-_animation.gif)
In human anatomy, the fibularis tertius is a muscle in the anterior compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to pull the foot upward toward the body (dorsiflexion).
![<span class="mw-page-title-main">Flexor hallucis brevis muscle</span> Muscle in sole of the foot that leads to the big toe](https://upload.wikimedia.org/wikipedia/commons/thumb/5/58/Musculus_flexor_hallucis_brevis.png/320px-Musculus_flexor_hallucis_brevis.png)
Flexor hallucis brevis muscle is a muscle of the foot that flexes the big toe.
![<span class="mw-page-title-main">Superficial fibular nerve</span> Nerve in the human leg and foot](https://upload.wikimedia.org/wikipedia/commons/4/43/Gray835.png)
The superficial fibular nerve is a mixed nerve that provides motor innervation to the fibularis longus and fibularis brevis muscles, and sensory innervation to skin over the antero-lateral aspect of the leg along with the greater part of the dorsum of the foot.
![<span class="mw-page-title-main">Deep fibular nerve</span> Type of nerve](https://upload.wikimedia.org/wikipedia/commons/4/43/Gray835.png)
The deep fibular nerve begins at the bifurcation of the common fibular nerve between the fibula and upper part of the fibularis longus, passes infero-medially, deep to the extensor digitorum longus, to the anterior surface of the interosseous membrane, and comes into relation with the anterior tibial artery above the middle of the leg; it then descends with the artery to the front of the ankle-joint, where it divides into a lateral and a medial terminal branch.

In humans, the sole of the foot is anatomically referred to as the plantar aspect.

The fibular retinacula are fibrous retaining bands that bind down the tendons of the fibularis longus and fibularis brevis muscles as they run across the side of the ankle.
![<span class="mw-page-title-main">Inferior extensor retinaculum of foot</span> Y-shaped band placed in front of the ankle-joint](https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/Gray441.png/320px-Gray441.png)
The inferior extensor retinaculum of the foot is a Y-shaped band placed in front of the ankle-joint, the stem of the Y being attached laterally to the upper surface of the calcaneus, in front of the depression for the interosseous talocalcaneal ligament; it is directed medialward as a double layer, one lamina passing in front of, and the other behind, the tendons of the peroneus tertius and extensor digitorum longus.

The fibularis muscles are a group of muscles in the lower leg.
![<span class="mw-page-title-main">Lateral compartment of leg</span>](https://upload.wikimedia.org/wikipedia/commons/thumb/c/c4/Leg_compartments.jpg/320px-Leg_compartments.jpg)
The lateral compartment of the leg is a fascial compartment of the lower leg. It contains muscles which make eversion and plantarflexion of the foot.
