Tarsal, any of several short, angular bones that in humans make up the ankle and that—in animals that walk on their toes ( e.g., dogs, cats) or on hoofs—are contained in the hock, lifted off the ground. The tarsals correspond to the carpal bones of the upper limb.
What bones articulate with the tarsals?
They have three or four articulations:

The carpals (wrist bones), tarsals (ankle and heel bones), and the patella (kneecap) are all short bones. Some experts consider the patella a sesamoid bone (discussed below) because it primarily provides an anchor point for tendons and ligaments.
What is the shaft of the long bone called?
Diaphysis. The diaphysis is the shaft of the long bone, the main body. The diaphysis is a tube with a hollow center called the medullary cavity (or marrow cavity). The wall of the diaphysis is made up of compact bone, which is dense and very hard. For most of the life of a long bone, the center of the diaphysis is filled with yellow bone marrow.

Short bones are called that because they about as wide as they are long. There is no diaphysis on a short bone. It is made up of spongy bone surrounded by compact bone just like the epiphysis. Short bones also contain red bone marrow.

Overview
Anatomy
- The tarsal bones articulate (attached by joints) with the bones of the metatarsus, a group of five long bones located between the tarsal bones and the phalanges (toe bones). The tarsus meets the ankle joint above, which connects to the tibia and fibula bones of the leg.2
Movement
- Movements that involve the tarsal bones include: 1. Inversion: The foot is tilted towards the body so that the sole of the foot faces inward toward the middle line of the body. 2. Eversion:The foot is tilted away from the body so that the sole of the foot faces outward, away from the middle line of the body. 3. Plantar Flexion: The toes of the foot point down. 4. Dorsiflexion: The foot tilts upwar…

Pronation:This movement describes landing on the outer side of the heel and the inward rolling and flatting of the foot. This is a normal and necessary movement of the foot while walking or running. Abnormal conditions can occur in which the pron…
