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]
The human foot has two longitudinal arches and a transverse arch maintained by the interlocking shapes of the foot bones, strong ligaments, and pulling muscles during activity. The slight mobility of these arches when weight is applied to and removed from the foot makes walking and running more economical in terms of energy.
The interosseous intercuneiform ligaments are short fibrous bands that connect the adjacent surfaces of the medial and intermediate, and the intermediate and lateral cuneiform bones. It is one of the 3 ligaments responsible for maintaining the transverse arch of the foot together with the interosseous ligaments of metatarsals and the transverse ...
The fibularis longus also tilts the sole of the foot away from the midline of the body . Because of the angle at which it crosses the sole of the foot, it plays an important role in maintaining the transverse arch of the foot. [2] Together, the fibularis muscles help to steady the leg upon the foot, especially in standing on one leg. [2]
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 ...

When the toes are dorsiflexed in the propulsive phase of gait, the plantar fascia becomes tense, resulting in elevation of the longitudinal arch and shortening of the foot (see 3A). One can liken this mechanism to a cable being wound around the drum of a windlass (see 3B); the plantar fascia being the cable, the metatarsal head the drum, and ...
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot (cuboid, medial, intermediate, and lateral cuneiform, and navicular) and hindfoot (talus and calcaneus).
