Tarsal
Tarsal
Tarsal (/ˈtɑːrsəl/), derived from the Greek word 'tarsos' meaning 'flat surface', refers to a group of seven bones in the foot located between the lower end of the tibia and fibula of the lower leg and the metatarsus.
Anatomy
The tarsal bones include the calcaneus, talus, navicular, cuboid, and three cuneiform bones. These bones are arranged to form the tarsal arch, which is essential for weight distribution across the foot.
Function
The primary function of the tarsal bones is to provide a strong support structure for the foot, enabling it to bear the weight of the body. They also play a crucial role in the foot's flexibility and movement, particularly in actions such as walking, running, and jumping.

- Tarsal Coalition: A congenital condition where two or more of the tarsal bones in the foot are fused together, limiting movement and often causing pain.
