Bony anatomy of the foot

Cuboid bone Author. Medial malleolus A pyramidal projection which is found on the distal end of the tibia on the medial side of the ankle.

The foot is a firm platform that support the weight of the body.

Bony anatomy of the foot. Below is a diagram demonstrating the bony anatomy of the foot. Identifiable below is the Medial Longitudinal Arch MLA of the foot. This consists of the calcaneus talus navicular medialintermedial cuneiform and 1 st metatarsal.

This however is not the only arch within the foot. In the foot there are two sesamoid bones located directly underneath the first metatarsal head embedded in the medial tibial side and lateral fibular aspect of the flexor hallucis brevis tendon. Common Ossicles of the Foot.

Some feet contain accessory ossicles or accessory bones Figure 9. These extra bones are developmental variants. The hindfoot is composed of 2 of the 7 tarsal bones the talus and the calcaneus.

The midfoot contains the rest of the tarsal bones. And the forefoot contains the metatarsals and the phalanges. The images below depict the bones of the foot.

Bones of the foot dorsal and ventral views. Besides the ankle joint which connects the foot with the leg the bones of the foot articulate among themselves through many synovial joints. There are four groups of foot joints.

Intertarsal tarsometatarsal metatarsophalangeal and interphalangeal. The intertarsal joints are between the tarsal bones. These joints are the subtalar talocalcaneal talocalcaneonavicular calcaneocuboid.

The anatomy of the foot. The foot contains a lot of moving parts - 26 bones 33 joints and over 100 ligaments. The foot is divided into three sections - the forefoot the midfoot and the hindfoot.

This consists of five long metatarsal bones and five shorter bones that form the toes phalanges. The tarsal bones of the foot are organised into three rows. Proximal intermediate and distal.

Proximal Group Hindfoot The proximal tarsal bones are the talus and the calcaneus. These comprise the hindfoot forming the bony framework around the proximal ankle and heel. The talus is the most superior of the tarsal bones.

It transmits the weight of the entire body to the foot. There are thirty three foot bones in humans making the foot and ankle a complex structure. The bones are arranged to be strong stable and yet flexible enough for movement.

The foot itself can be divided into three sections. The hindfoot midfoot and forefoot and the foot bones can be grouped into three sets. The tarsal bones the metatarsals and the phalanges.

Medial malleolus A pyramidal projection which is found on the distal end of the tibia on the medial side of the ankle. It articulates with the medial surface of the talus. Lateral malleolus A pryramidal projection which is found on the distal fibula.

Talus - A tarsal bone which articulates with the tibia fibula calcaneus. Bones of the foot as seen from the medial arch side. The foot is a firm platform that support the weight of the body.

It is made up of many bones including the tarsal bones the metatarsal bones and the phalanges described in more detail below. The Foot Lets identify the bones of the foot. Notice that the great toe only has a proximal and distal phalange.

There are also 2 sesamoid bones not shown located under the 1st MTP joint. Middle phalange metatarsal middle cuneiform distal phalange proximal phalange lateral cuneiform medial cuneiform navicular talus cuboid calcaneous. The calcaneus heel bone is the largest bone in the foot.

Muscles tendons and ligaments run along the surfaces of the feet allowing the complex movements needed for motion and balance. The primary bones in the foot are the tarsals bones connecting the lower leg to the foot metatarsals long bones of the foot and phalanges five bones in the toes 2. This section of the foot is made up of five irregularly shaped bones called the tarsals.

The clinical names for these bones are the navicular cuboid and medial intermediate and lateral cuneiforms. Together they form the arch of the foot. The arch of the foot plays a key role in weight-bearing and stability.

The fascia in the foot is composed of fibrous connective tissue that serves to separate support and attach muscles. It can be divided into the superficial fascia and the deep fascia. The superficial fascia is located just beneath the skin and.

October 28 2021 Reading time. 5 minutes The cuboid bone is a short bone in the lateral part of the foot located on the distal row of the tarsal bonesIt is square shaped hence the name and is the main bone of the mid foot due to the several articular surfaces it possesses. The flexor hallucis brevis muscle is located on the medial side of the foot.

It originates from two places on the sole of the foot. Originates from the plantar surfaces of the cuboid and lateral cuneiforms and from the tendon of the posterior tibialis tendon. Attaches to the base of the proximal phalanx of the great toe.

The bony ligamentous and muscular structures of the ankle and foot are presented with respect to their mobility and stability functions. Innervation and vascular supply are discussed. Normal anatomy provides a basis and a reference point for discussion of dysfunction of the ankle and foot.

In this article well discuss the different components of the basic anatomy of the human foot including its major bones muscles tendons nerves and blood vessels. Bones of the human foot. The bones of the foot begin with the two bones that make up the lower leg the tibia and fibula.

These join with the talus bone to form the ankle. The bones of the feet are. Talus the bone on top of the foot that forms a joint with the two bones of the lower leg the tibia and fibula.

Calcaneus the largest bone of the foot which lies beneath the talus to form the heel bone. Tarsals five irregularly shaped bones of the midfoot that form the foots arch. The foot contains 26 bones 33 joints and over 100 tendons muscles and ligaments.

This may sound like overkill for a flat structure that supports your weight but you may not realize how much work your foot does. The foot is responsible for balancing the bodys weight on two legs a feat which modern roboticists are still trying to replicate. Fifth Metatarsal Head This is the bony prominence on the lateral side of your foot and its a really important muscular attachment point.

Proximal Medial and Distal Phalanges On from your metatarsals are your phalanges. 46833 foot anatomy stock photos vectors and illustrations are available royalty-free. See foot anatomy stock video clips.
