Question

What kind of bones does the tarsus contain?

Answer 1

Seven articulating bones, two regular - A talus and calcaneus, and five irregular - a cuboid, navicular and three cuneiform bones.

Explanation:

The tarsus is the collection of bones which connect the metatarsal's to the tibia and fibular, while also providing strength and structure. They make up the the foot, and there are seven of them, as follows:

The talus - Known as the ankle bone, it connects with the fibular and tibia superiorly to form the ankle joint, and joins with the calcaneus inferiorly to form the heel bone and the hindfoot.
By also connecting with the naivcular, and that joint connecting with the calcaneocuboid joint to form the transverse tarsal joint, it forms most of the basis of movement in the foot.

Although irregular in shape, the talus is split up into three parts - the head, neck and body - which are regular in shape. Additionally, no muscle attatches to the talus, so its position relies entirely on the other bones.

The calcaneus - The largest bone, it articulates with the talus both anteriorly and posteriorly, and with the cuboid bone anteriorly. It forms the hindfoot with the talus, is regular in shape, and is commonly known as the heel bone.https://en.wikipedia.org/wiki/Calcaneus

The navicular - Named for its resemblance to a small boat, the navicular has three bone articulations in the foot - a proximal one with the talus, a lateral one with the cuboid, and a distal one with the three cuneiform bones.

The cuboid - Named for its cubic shape, the cuboid articulates with three bones - the navicular, the third cuneiform, and the calcaneus. It also makes a joint with the fourth and fifth metatarsals.

The medial, intermediate and lateral cuneiforms - The medial is the largest bone, and articulates with the navicular, intermediate cuneiform, and the first and second metatarsals.

The intermediate is the middle bone in terms of position, and connect to the other cueniform bones. It also connects posteriorly to the navicular, and anteriorly to the second metatarsal.

The lateral cuneiform is often called the external cuneiform, and it articulates with the navicular posteriorly, the cuboid laterally, the intermediate medially and the third metatarsal.
