Plantar arch

Plantar Arch

The Plantar Arch is a significant anatomical structure found in the human foot. It is formed by the tarsal bones and metatarsal bones, and is supported by various ligaments and tendons. The plantar arch plays a crucial role in distributing body weight and absorbing shock during movement.

Etymology[edit | edit source]

The term "plantar" is derived from the Latin word "planta," which means "sole of the foot." The word "arch" comes from the Latin "arcus," meaning "bow," which refers to the curved shape of this structure.

Anatomy[edit | edit source]

The plantar arch is made up of the five metatarsal bones, the cuboid bone, and the three cuneiform bones. These bones form a half-dome shape, which is the arch. The arch is maintained by the plantar fascia, a thick band of tissue that connects the heel to the toes, and the plantar ligaments, which connect the bones of the foot.

Function[edit | edit source]

The primary function of the plantar arch is to distribute body weight across the foot. This allows for even pressure distribution during standing, walking, running, and other activities. The arch also acts as a shock absorber, reducing the impact on the foot when it hits the ground.

Related Terms[edit | edit source]

Flatfoot: A condition where the plantar arch is flattened, causing the entire sole of the foot to touch the ground.
High arch: A condition where the plantar arch is higher than normal, causing an uneven distribution of weight across the foot.
Plantar fasciitis: Inflammation of the plantar fascia, often causing heel pain.
