In humans and many other primates, the calcaneus (/ k æ l ˈ k eɪ n i ə s /; from the Latin calcaneus or calcaneum, meaning heel; [1] pl.: calcanei or calcanea) or heel bone is a bone of the tarsus of the foot which constitutes the heel. In some other animals, it is the point of the hock.
However, human feet, and the human medial longitudinal arch, differ in that the anterior part of the foot is medially twisted on the posterior part of the foot, [12] so that all the toes may contact the ground at the same time, and the twisting is so marked that the most medial toe, the big toe or hallux, (in some individuals the second toe ...
Skeletons of a human and an elephant. Comparative foot morphology involves comparing the form of distal limb structures of a variety of terrestrial vertebrates.Understanding the role that the foot plays for each type of organism must take account of the differences in body type, foot shape, arrangement of structures, loading conditions and other variables.
Hallux varus is a clinical condition characterized by medial deviation of the great toe at the metatarsophalangeal joint. [2] This condition, when acquired by adults, is usually caused by sports injury, surgical overcorrection of hallux valgus, or underlying causes such as arthritides.
The leg of an unguligrade mammal also includes the phalanges, the finger and toe bones. Among extinct animals, most early mammals such as pantodonts were plantigrade. A plantigrade foot is the primitive condition for mammals; digitigrade and unguligrade locomotion evolved later.
Calluses (plantar in right foot and medial in left foot) A callus (pl.: calluses) is an area of thickened and sometimes hardened skin that forms as a response to repeated friction, pressure, or other irritation. Since repeated contact is required, calluses are most often found on the feet and hands, but they may occur anywhere on the skin.
These kicks, built for “right-out-of-the-box comfort,’ have a secret weapon you won’t find in many other fashion-forward footwear: memory foam from heel to toe.
Functional motion during the gait cycle is 10-15 degrees (the heel strikes the ground in slight inversion followed by quick eversion). [ 2 ] The talonavicular and calcaneocuboid joints (i.e. between the talus and navicular bones, and the calcaneus and cuboid bones) form the so-called transverse tarsal joint or Chopart's joint.
