Medial Foot Anatomy

Note that plantar muscles can also be studied as four layers but here they are presented as groups. This may sound like overkill for a flat structure that supports your weight but you may not realize how much work your foot does.

Applied Surgical Anatomy Of The Approaches To The Ankle

The muscles lying within the medial group form a bulge referred to as the ball of the big toe.

Medial foot anatomy. It contributes to the surface anatomy of the medial sole of the foot and is easy to palpate. For example in a human imagine a line down the center of the body from the head though the navel and going between the legs the medial side of the foot would be the big toe side. The forefoot contains the five toes phalanges and the five longer bones metatarsals.

The foot contains 26 bones 33 joints and over 100 tendons muscles and ligaments. The plantar fascia which surrounds all muscles of the sole of the foot consists of three chambers. This branch of the tibial nerve runs between the abductor hallucis and flexor digitorum brevis in the foot.

The foot is responsible for balancing the bodys weight on two legs a feat which modern roboticists are still trying to replicate. A wedge shaped bone that makes up the joints of the middle foot. It innervates the skin of the medial side of the sole of the foot and its the nerve supply for the some of the foot muscles.

This gives the human foot an everted or relatively outward facing appearance compared. Lateral central and medial. The term medial from latin medius meaning middle is used to refer to structures close to the centre of an organism called the median plane.

Two longitudinal medial and lateral arches and one anterior transverse arch. It is located on the inside of the foot behind the first metatarsal a bone of the big toe and in front of the navicular. The midfoot is a pyramid like collection of bones that form the.

The feet are divided into three sections. The largest of the cuneiform bones it anchors several ligaments in the foot. The plantar foot muscles are divided into three groups of muscles by the deep fasciae of the foot.

The lateral plantar muscles act upon the fifth toe. They are formed by the tarsal and metatarsal bones and supported by ligaments and tendons in the foot. The foot has three arches.

However human feet and the human medial longitudinal arch differ in that the anterior part of the foot is medially twisted on the posterior part of the foot so that all the toes may contact the ground at the same time and the twisting is so marked that the most medial toe the big toe or hallux in some individuals the second toe tends to exert the greatest propulsive force in walking and running. This image shows the topographical anatomy of the medial aspect of the foot and ankle. The medial side of the knee would be the side adjacent to the other knee.
