The Foot : The foot contains the proximal tarsals that form the ankle and heel; intermediate metatarsals; and the distal phalanges that form the toes.
The tarsal bones of the foot are organized into three rows: proximal, intermediate, and distal. The proximal row contains the talus, which is the most superior of the tarsals and articulates with the tibia and fibula to form the ankle joint. The talus is responsible for transmitting forces from the tibia to the heel and acts as an attachment point for numerous ligaments that strengthen the ankle joint. The calcaneus is the thickest tarsal and forms the heel of the foot.
It articulates with the talus superiorly and anteriorly with the cuboid of the distal group. Posteriorly the calcaneal tuberosity is the attachment point for the Achilles tendon. The intermediate group contains only the navicular bone, which articulates with all of the tarsals—with the exception of the calcaneus. The navicular bone plays a key role in maintaining the medial longitudinal arch of the foot. There are four distal tarsals: the lateral cuboid and the three cuneiforms, located medially.
The distal tarsals articulate with the metatarsals and also maintain the transverse arch of the foot. The foot contains five metatarsals that are numbered I—V, moving medial to lateral, big toe to little toe.
Each metatarsal consists of a head, shaft, and base. The proximal base articulates with the cuboid bones, and distally with the proximal phalanges, and each metatarsal also articulates laterally with adjacent metatarsals. These bones are found between the phalanges of the toes and the tarsal bones. The metatarsal bones are connected to the bones of the toe, or phalanges, at the knuckle of the toe, or metatarsophalangeal joint. Metatarsals are convex in shape arch upward , are long bones, and give the foot its arch.
They work with connective tissues, ligaments and tendons, to provide movement in the foot. These bones can become fractured, strained, or inflamed from misuse or overuse. Immobilization of the foot e. The cuboid bone is one of the seven tarsal bones located on the lateral outer side of the foot. This bone is cube-shaped and connects the foot and…. The flexor digitorum brevis muscle is located in the foot. Its precise location is within the sole of the foot, directly above the plantar aponeurosis,.
The dorsal calcaneocuboid ligament is part of a group of muscular fibers in the foot. As it is fasciculus, the ligament is both small and broad. The dorsal tarsometatarsal ligament is located in the foot. It provides connections among the bones of the feet. The metatarsals are the long bones of…. The distal phalanges foot are located at the end of each toe.
Three phalangeal bones make up each digit, articulating with each other at bending…. In the foot, there are three cuneiform bones. They are the intermediate, lateral, and mediate cuneiforms. The flexor digiti minimi brevis foot is a muscle that is located on the outer edge of the foot bones.
It begins at the fifth metatarsal the bone…. The middle phalanges foot are some of the smaller long bones that form the toes of the feet.
