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]
Additionally, the Ottawa ankle rules indicate whether a foot X-ray series is required. It states that it is indicated if: There is any pain in the midfoot zone; and, Any one of the following: Bone tenderness at the base of the fifth metatarsal (for foot injuries), OR; Bone tenderness at the navicular bone (for foot injuries), OR
Lateral X-ray of a flat foot with C-sign, which is a bony bridge between the talar dome and sustentaculum tali, in combination with a prominent inferior border of the sustentaculum tali. This represents a talocalcaneal coalition, which is an abnormal connection between the talus and calcaneus and is thought to cause the flat foot deformity in ...
Pes cavus, also known as high arch, is an orthopedic condition that presents as a hollow arch underneath the foot with a pronounced high ridge at the top when weight bearing. This foot type is typically characterized with cavus—the elevation of the longitudinal plantar arch (e.g., the bottom arch of a foot), plantar flexion of the foot ...
The hind limb and foot of the elephant are oriented semi-plantigrade, and closely resemble the structure and function of the human foot. The tarsals and metapodials are arranged so as to form an arch, similarly to the human foot. The six toes of each foot of the elephant are enclosed in a flexible sheath of skin.
The navicular bone is a keystone of the foot: it is part of the coxa pedis and articulates with the talus, first, second and third cuneiform, cuboid and calcaneus. It plays an important role in the biomechanics of the foot, helping in inversion, eversion, and motion; it is a structural link between midfoot and forefoot and it is part of the ...

The plantar arch is a circulatory anastomosis formed from: deep plantar artery, from the dorsalis pedis - a.k.a. dorsal artery of the foot; lateral plantar artery; The plantar arch supplies the underside, or sole, of the foot. The plantar arch runs from the 5th metatarsal and extends medially to the 1st metatarsal (of the big toe).
