Foot (fʊt)
The foot is a part of the human body located at the lower extremity of the leg. It is used for standing, walking, running, and other forms of locomotion. The foot is an essential component of the body's overall anatomy and physiology, playing a crucial role in balance, mobility, and weight-bearing.
Etymology
The term "foot" comes from the Old English fōt, from Proto-Germanic *fōts, from Proto-Indo-European *pṓds.
Anatomy of the Foot
The foot consists of several key components:
- Toes: These are the five digits located at the front of the foot. They assist in balance and propulsion during walking and running.
- Metatarsal bones: These are the five long bones in the foot. They are numbered from one to five, with one being the bone connected to the big toe and five being connected to the little toe.
- Tarsal bones: These are the seven bones that make up the back part of the foot and heel. They include the talus, calcaneus, navicular, three cuneiform bones, and the cuboid.
- Arch of the foot: This is the curved, springy part of the foot between the toes and the heel. It helps to distribute body weight across the foot.
