The dorsal talonavicular ligament is a broad, thin band, which connects the neck of the talus to the dorsal surface of the navicular bone; it is covered by the Extensor tendons.
The talus, talus bone, astragalus, or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint through its articulations with the lateral and medial malleoli of the two bones of the lower leg, the tibia and fibula. Within the tarsus, it articulates with the calcaneus below and navicular in front within the talocalcaneonavicular joint. Through these articulations, it transmits the entire weight of the body to the foot.
The navicular bone is a small bone found in the feet of most mammals.
The plantar calcaneonavicular supplies the place of a plantar ligament for this joint.
In the human body, the cuboid bone is one of the seven tarsal bones of the foot.
In human anatomy, the dorsal interossei of the foot are four muscles situated between the metatarsal bones.
The medial plantar nerve is the larger of the two terminal divisions of the tibial nerve, which accompanies the medial plantar artery.
The long plantar ligament is a long ligament on the underside of the foot that connects the calcaneus with the cuboid bone.
The cuneonavicular joint is a joint (articulation) in the human foot. It is formed between the navicular bone and the three cuneiform bones. The navicular and cuneiform bones are connected by dorsal and plantar ligaments.
The cuboideonavicular joint is a joint (articulation) in the foot formed between the navicular bone and cuboid bone. The navicular bone is connected with the cuboid bone by the dorsal, plantar, and interosseous cuboideonavicular ligaments.
The talocalcaneonavicular joint is a ball and socket joint: the rounded head of the talus being received into the concavity formed by the posterior surface of the navicular, the anterior articular surface of the calcaneus, and the upper surface of the plantar calcaneonavicular ligament.
The calcaneocuboid joint is the joint between the calcaneus and the cuboid bone.
The plantar calcaneocuboid ligament is a ligament on the bottom of the foot that connects the calcaneus to the cuboid bone. It lies deep to the long plantar ligament.
The plantar calcaneonavicular ligament is a complex of three ligaments on the underside of the foot that connect the calcaneus with the navicular bone.
The tarsometatarsal joints are arthrodial joints in the foot. The tarsometatarsal joints involve the first, second and third cuneiform bones, the cuboid bone and the metatarsal bones. The eponym Lisfranc joint is named after 18th-19th century surgeon and gynecologist, Jacques Lisfranc de St. Martin.
Intermetatarsal joints - The base of the first metatarsal is not connected with that of the second by any ligaments; in this respect the great toe resembles the thumb.
The interphalangeal joints of the foot are between the phalanges (bones) of the toes. Since the great toe only has two phalanx bones, it only has one interphalangeal joint, which is often abbreviated as the "IP joint." The rest of the toes each have three phalanx bones, so they have two interphalangeal joints: the proximal interphalangeal joint between the proximal and middle phalanges and the distal interphalangeal joint between the middle and distal phalanges. All interphalangeal joints are ginglymoid (hinge) joints, and each has a plantar (underside) and two collateral ligaments. In the arrangement of these ligaments, extensor tendons supply the places of dorsal ligaments, which is similar to that in the metatarsophalangeal articulations.
The intercuneiform joints are the joints the cuneiform bones.
The fifth metatarsal bone is a long bone in the foot, and is palpable along the distal outer edges of the feet. It is the second smallest of the five metatarsal bones. The fifth metatarsal is analogous to the fifth metacarpal bone in the hand
The fourth metatarsal bone is a long bone in the foot. It is smaller in size than the third metatarsal bone and is the third longest of the five metatarsal bones. The fourth metatarsal is analogous to the fourth metacarpal bone in the hand
The third metatarsal bone is a long bone in the foot. It is the second longest metatarsal. The longest being the second metatarsal. The third metatarsal is analogous to the third metacarpal bone in the hand
The first metatarsal bone is the bone in the foot just behind the big toe. The first metatarsal bone is the shortest of the metatarsal bones and by far the thickest and strongest of them.
The plantar tarsometatarsal ligaments consist of longitudinal and oblique bands, disposed with less regularity than the dorsal ligaments.
In the human foot, the plantar or volar plates are fibrocartilaginous structures found in the metatarsophalangeal (MTP) and interphalangeal (IP) joints. The anatomy and composition of the plantar plates are similar to the palmar plates in the metacarpophalangeal (MCP) and interphalangeal joints in the hand; the proximal origin is thin but the distal insertion is stout. Due to the weight-bearing nature of the human foot, the plantar plates are exposed to extension forces not present in the human hand.

Gray's Anatomy is an English language textbook of human anatomy originally written by Henry Gray and illustrated by Henry Vandyke Carter. Earlier editions were called Anatomy: Descriptive and Surgical, Anatomy of the Human Body and Gray's Anatomy: Descriptive and Applied, but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy. The book is widely regarded as an extremely influential work on the subject, and has continued to be revised and republished from its initial publication in 1858 to the present day. The latest edition of the book, the 41st, was published in September 2015.
