Answer
The foot has three arches: the medial longitudinal arch, the lateral longitudinal arch and the transverse arch. Thet function to to absorb stress and to distribute the bod's weight between the heel and the heads of the metacarpal bones.
The medial longitudinal (MLA) extends from the heel to the hallux (big toe). Its components are the calcaneus , the talus, the navicular, three cuneiforms and metatarsals I-III.
The lateral longitudinal arch extends from heel to little toe (fifth pedal digit). It includes the the calcaneus, the cuboid, and metatarsals IV and V.
The third arch is the transverse arch --sometimes called the metatarsal arch. It is composed of the following bones cuboid the metatarsals (proximal ends/heads), and the three cuneiforms; unlike the longitudinal arches, its trajectory/course is from side to side
Work Step by Step
The arches of the foot are held in place and supported by ligaments.
