Tarsus
Tarsus (anatomy)
Tarsus (pronunciation: /ˈtɑːrsəs/) is a cluster of seven articulating bones in each foot situated between the lower end of tibia and fibula of the lower leg and the metatarsus. It is made up of the talus, calcaneus, navicular bone, and the cuboid and three cuneiform bones.
Etymology
The term "tarsus" is derived from the Greek word "tarsos", which means "flat surface". This is in reference to the relatively flat structure of the bones in this region.
Function
The tarsus forms the lower part of the ankle joint through its articulation with the tibia and fibula. It also forms the heel and the back part of the foot. The bones of the tarsus do not only provide support and stability to the foot, but they also play a crucial role in its flexibility and movement.
