Tarsal bones
Ossa tarsi
- Latin synonym: Ossa tarsea
Definition
The foot consists of seven tarsal bones, arranged in two rows: the proximal and distal rows.
The proximal row comprises the talus (above) and calcaneus (below), forming the hindfoot.
The distal row forms the midfoot and consists of four tarsal bones: the cuboid, lateral cuneiform, intermediate cuneiform, and medial cuneiform bones (from lateral to medial). In addition, the navicular bone, located between the calcaneum and the three cuneiform bones, is considered the fifth tarsal bone of the midfoot (link).
These tarsal bones are sturdy structures that provide support and help distribute the body weight.
