What are the bones of the foot?
Bones of the Foot: Tarsals, Metatarsals and Phalanges. The bones of the foot provide mechanical support for the soft tissues; helping the foot withstand the weight of the body whilst standing and in motion. Tarsals – a set of seven irregularly shaped bones. They are situated proximally in the foot in the ankle area.
What joint is between the talus and the navicular?
Anteriorly – talonavicular joint – between the talus and the navicular.
Which aspect of the calcaneus is marked by calcaneal tuberosity?
It protrudes posteriorly and takes the weight of the body as the heel hits the ground when walking. The posterior aspect of the calcaneus is marked by calcaneal tuberosity, to which the Achilles tendon attaches.
Which bone is the most lateral in the distal row of tarsal bones?
The cuboid bone posteriorly articulates with the end of the calcaneus. It is the most lateral bone in distal row of tarsal bones. Anterior to the cuboid tuberosity, on the lateral and inferior surfaces of the bone is a groove which provides passage for a muscle tendon.
How many bones are there in the foot?
Introduction. The skeleton of the foot consists of 26 bones and these can be grouped into three groups: There are 7 tarsal bones, 5 metatarsal bones and 14 phalanges. Anatomically the foot can be divided into the forefoot (metatarsals and phalanges), the midfoot (cuboid, navicular and cuneiforms) and the hindfoot (calcaneus and talus).
What are the bones of the posterior aspect of the foot?
The tarsus. The tarsus consists of 7 bones which make the posterior aspect of the foot: talus, calcaneus, cuboid, navicular and three cuneiforms. The tarsal bones can be divided into the hindfoot (talus and calcaneus) and midfoot (cuboid and cuneiforms). The navicular is the intermediate bone between these two groups.
What bone articulates with the talus?
Anteriorly the talus articulates with the navicular bone. Medially the talus articulates with the intermediate bone of the talus. The talus has a body, head and neck.
What is the most superior bone of the tarsus?
Talus (Latin for ankle) talus is the most superior bone of the tarsus and rests on top of the calcaneus. Three areas of articulation form the ankle joint: The superomedial aspect of the talus articulates with the medial malleolus of the tibia.
Where is the navicular bone located?
The navicular is located between the head of the talus posteriorly and the three cuneiforms anteriorly. The navicular bone is on the medial aspect of the foot and articulates with the talus proximally, the three cuneiforms distally and the cuboid laterally.
How many bones are there in the anterior portion of the foot?
The anterior portion of the foot is formed by the 5 metatarsal bones which are numbered 1-5 starting from the medial aspect of the foot. The first metatarsal is shorter and thicker than the others. Each metatarsal has a base (proximally), a shaft, and a head (distally).
What are the bones of the foot called?
The metatarsus of the foot consists of five long bones, which are called the metatarsals. Like the metacarpals of the hand, the metatarsals are comprised of a proximal base, a shaft and a distal head.
Where is the fifth metatarsal?
The fifth metatarsal has a tuberosity lateral to the base, which can be both seen and felt on the lateral border of the foot. The base articulates with the cuboid proximally by a triangular surface and medially with the fourth metatarsal. Its head also articulates with the 5th proximal phalanx.
What are the main functions of the metatarsals?
Function. Along with the calcaneus, the metatarsals are involved in supporting the weight of the body. The metatarsus has 5 main points of contact with the ground: The 1st metatarsal head and two sesamoid bones. The 2nd metatarsal head.
Which metatarsal is smaller than the third?
The fourth metatarsal is smaller than the third and has 3 articular facets at its base. Proximally, it has a quadrilateral facet, which articulates with the cuboid. There is an oval facet medially which articulates with the third metatarsal and there is another single facet on the lateral surface for articulation of the fifth metatarsal. Distally, the head articulates with the 4th proximal phalanx.
Which metatarsal has a triangular base?
The third metatarsal has a triangular base, which articulates proximally with the lateral cuneiform.

Anatomy
- The tarsal bones articulate (attached by joints) with the bones of the metatarsus, a group of five long bones located between the tarsal bones and the phalanges (toe bones). The tarsus meets the ankle joint above, which connects to the tibia and fibula bones of the leg.2
Movement
- Movements that involve the tarsal bones include: 1. Inversion: The foot is tilted towards the body so that the sole of the foot faces inward toward the middle line of the body. 2. Eversion:The foot is tilted away from the body so that the sole of the foot faces outward, away from the middle line of the body. 3. Plantar Flexion: The toes of the foot point down. 4. Dorsiflexion: The foot tilts upwar…
Pronation and Supination
- Supination and pronation are movements that your foot makes while it strikes the ground during active motion, such as while running. 1. Pronation:This movement describes landing on the outer side of the heel and the inward rolling and flatting of the foot. This is a normal and necessary movement of the foot while walking or running. Abnormal conditions can occur in which the pron…
Tarsal Fractures
- A tarsal fracture is a fracture of any of the tarsal bones of the foot. They are rare and can occur from impact injuries or due to force from repetitive actions. Stress fractures or hairline fractures most often affect the calcaneus or navicular bones.5
A Word from Verywell
- At any age and activity level, taking care of your feet is important. This means staying active, avoiding banging on hard surfaces or excessively repetitive activities, and wearing footwear that gives you the support and cushioning you need.
