cuneiform bone

There are three cuneiform bones in the human foot:

Mere gliding movements are permitted between the navicular and cuneiform bones.

The dorsal ligaments are three small bundles, one attached to each of the cuneiform bones.

These include the three cuneiform bones, the cuboid bone, and the navicular bone.

The Cuneonavicular articulation is a joint formed between the navicular bone and the three cuneiform bones.

The intercuneiform articulations are articulations among the cuneiform bones.

The navicular and cuneiform bones is connected by dorsal and plantar ligaments.

The tibialis anterior and fibularis longus muscle inserts at the medial cuneiform bone.

It is on the outer side of the foot and is next to the calcaneus, navicular and lateral cuneiform bones.

The first metatarsal articulates (forms joints) with the medial cuneiform, and to a small extent to the intermediate cuneiform bone.

Flexor hallucis brevis muscle arises on the medial cuneiform bone and related ligaments and tendons.

The Plantar intercuneiform ligaments are fibrous bands that connect the plantar surfaces of adjacent cuneiform bones.

Under the foot it splits into a thick medial part attached to the navicular bone and a slightly weaker lateral part inserted to the three cuneiform bones.

The second metatarsal bone is the longest of the metatarsal bones, being prolonged backward and held firmly into the recess formed by the three cuneiform bones.

The five irregular bones of the midfoot, the cuboid, navicular, and three cuneiform bones, form the arches of the foot which serves as a shock absorber.

The Plantar cuneocuboid ligament is a fibrous band that connects the plantar surfaces of the cuboid to the lateral surface of the cuneiform bones.

Lateral to the abductor hallucis is the flexor hallucis brevis, which originates from the medial cuneiform bone and from the tendon of the tibialis posterior.

The lateral cuneiform (also known as third cuneiform or external cuneiform) intermediate in size between the other two cuneiform bones, is also wedge-shaped, the base being uppermost.

The bundle connecting the navicular with the medial cuneiform bone is continuous around the medial side of the articulation with the plantar ligament which unites these two bones.

The dorsal cuneonavicular ligaments consist of fibrous bands that join the dorsal surface of the navicular bone to the dorsal surfaces of the three cuneiform bones.

The bones of the tarsus are the rear most bones in the adjacent diagram: calcaneus, talus, navicular, cuboid, medial cuneiform, intermediate cuneiform and lateral cuneiform bones.

The lateral rays stretch over the cuboid bone to the heel bone and the medial rays over the three cuneiform bones and the navicular bone to the ankle bone.

The second metatarsal forms joints with the second proximal phalanx (a bone in the second toe) through the metacarpophalangeal joint, the cuneiform bones, third metatarsal and occasionally the first metatarsal bone.

The navicular bone in humans is located on the medial side of the foot, and articulates proximally with the talus, distally with the three cuneiform bones, and laterally with the cuboid.

It is situated between the other two cuneiform bones (the medial and lateral cuneiforms), and articulates with the navicular posteriorly, the second metatarsal anteriorly and with the other cuneiforms on either side.
