The tarsus articulates with the bones of the metatarsus, which in turn articulate with the proximal phalanges of the toes. The joint between the tibia and fibula above and the tarsus below is referred to as the ankle joint proper. In humans the largest bone in the tarsus is the calcaneus, which is the weight-bearing bone within the heel of the ...
The anatomy and shape of a person's longitudinal and transverse arch can dictate the types of injuries to which that person is susceptible. The height of a person's arch is determined by the height of the navicular bone. Collapse of the longitudinal arches results in what is known as flat feet. [5]
In humans, the calcaneus is the largest of the tarsal bones and the largest bone of the foot. Its long axis is pointed forwards and laterally. [2] The talus bone, calcaneus, and navicular bone are considered the proximal row of tarsal bones. [3] In the calcaneus, several important structures can be distinguished: [3]
A crurotarsal joint is one that's situated between the bones of crus, i.e. shin (tibia and fibula) and the proximal tarsal bones, i.e. astragalus and calcaneum. [ 1 ] [ 2 ] The ankle joint of therian mammals ( marsupials and placentals ) is a crurotarsal joint, with the main joint of ankle bending between the tibia and the astragalus; the ...
Tarsus (skeleton), a cluster of articulating bones in each foot; Hock (anatomy), the region formed by the tarsal bones connecting the tibia and metatarsus of a digitigrade or unguligrade quadrupedal mammal; Tarsus (eyelids), elongated plate of dense connective tissue in each eyelid; The distal segment of an arthropod leg – see Arthropod tarsus
The hindfoot is composed of the talus (or ankle bone) and the calcaneus (or heel bone). The two long bones of the lower leg, the tibia and fibula, are connected to the top of the talus to form the ankle. Connected to the talus at the subtalar joint, the calcaneus, the largest bone of the foot, is cushioned underneath by a layer of fat. [2]
The carpus and tarsus of land vertebrates primitively had three rows of carpal or tarsal bones. Often, some of these have become lost or fused in evolution. Accessory bones amidst tarsals. Three proximal bones. Humans hold all three in their hands.
The synovial membrane between the second and third cuneiforms behind, and the second and third metatarsal bones in front, is part of the great tarsal synovial membrane. Two prolongations are sent forward from it, one between the adjacent sides of the second and third, and another between those of the third and fourth metatarsal bones.
