Extensor digitorum brevis muscle. The mucous sheaths of the tendons around the ankle. Lateral aspect. (Extensor dig. brevis labeled at upper right.) The extensor digitorum brevis muscle (sometimes EDB) is a muscle on the upper surface of the foot that helps extend digits 2 through 4.
The extensor digitorum muscle (also known as extensor digitorum communis) [ 2 ] is a muscle of the posterior forearm present in humans and other animals. It extends the medial four digits of the hand. Extensor digitorum is innervated by the posterior interosseous nerve, which is a branch of the radial nerve. [ 3 ]
Extensor digitorum brevis manus is an extra or accessory muscle on the backside (dorsum) of the hand. It was first described by Albinus in 1758. [1] The muscles lies in the fourth extensor compartment of the wrist, and is relatively rare. [2] It has a prevalence of 4% in the general population according to a meta-analysis. [3]
The extensor indicis proprius usually runs and inserts onto the ulnar side of the extensor digitorum communis of the index finger. [4] The fifth compartment is occupied by the extensor digiti minimi, the extensor of the little finger. The extensor carpi ulnaris passes through the sixth compartment to insert to the base of the fifth metacarpal bone.
The common extensor tendon serves as the upper attachment (in part) for the superficial muscles that are located on the posterior aspect of the forearm: The tendon of extensor carpi radialis brevis is usually the most major tendon to which the other tendons merge. [2]
Superficial. Deep. The extrinsic extensor muscles of the hand are located in the back of the forearm and have long tendons connecting them to bones in the hand, where they exert their action. Extrinsic denotes their location outside the hand. Extensor denotes their action which is to extend, or open flat, joints in the hand.
The muscles of the hand are the skeletal muscles responsible for the movement of the hand and fingers. The muscles of the hand can be subdivided into two groups: the extrinsic and intrinsic muscle groups. The extrinsic muscle groups are the long flexors and extensors. They are called extrinsic because the muscle belly is located on the forearm.
Extensor tendon compartments of the wrist are anatomical tunnels on the back of the wrist that contain tendons of muscles that extend (as opposed to flex) the wrist and the digits (fingers and thumb). The extensor tendons are held in place by the extensor retinaculum. As the tendons travel over the posterior (back) aspect of the wrist they are ...
