The posterior compartment of the forearm (or extensor compartment) contains twelve muscles which primarily extend the wrist and digits. [2] It is separated from the anterior compartment by the interosseous membrane between the radius and ulna .
The anterior compartment of the forearm (or flexor compartment) [1] contains the following muscles: [2] ... Posterior compartment of the forearm; References
Ultimately, the forearm is covered by skin, the anterior surface usually being less hairy than the posterior surface. The forearm contains many muscles, including the flexors and extensors of the wrist, flexors and extensors of the digits, a flexor of the elbow (brachioradialis), and pronators and supinators that turn the hand to face down or ...
The term "anterior", while anatomically correct, can be confusing when describing the palm of the hand; Similarly is "posterior", used to describe the back of the hand and arm. This confusion can arise because the forearm can pronate and supinate and flip the location of the hand.
Anterior (at top) and posterior (at bottom) compartments. The anterior compartment of the arm is also known as the flexor compartment of the arm as its main action is that of flexion. The anterior compartment is one of the two anatomic compartments of the upper arm, the other being the posterior compartment.
the brachial region encompassing the upper arm, the olecranal region encompassing the back of the elbow, the antebrachial region encompasses the forearm, front and back; and the manual or manus region encompassing the back of the hand. The posterior regions of the legs, from superior to inferior, include the gluteal region encompassing the ...
Despite the bulk of the muscle body being visible from the anterior aspect of the forearm, the brachioradialis is a posterior compartment muscle and consequently is innervated by the radial nerve. [5] Of the muscles that receive innervation from the radial nerve, it is one of only four that receive input directly from the radial nerve.
The fascial compartments of the forearm are the posterior compartment of the forearm and the anterior compartment of the forearm. [1 References. This page ...
