The forearm is the region of the upper limb between the elbow and the wrist. [1] The term forearm is used in anatomy to distinguish it from the arm, a word which is used to describe the entire appendage of the upper limb, but which in anatomy, technically, means only the region of the upper arm, whereas the lower "arm" is called the forearm.
There are generally twelve muscles in the posterior compartment of the forearm, which can be further divided into superficial, intermediate, and deep. Most of the muscles in the superficial and the intermediate layers share a common origin which is the outer part of the elbow, the lateral epicondyle of humerus.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
Forearm anatomy. Forearm exercises strengthen the muscles that cross over your elbows, wrists and hands and help improve your ability to perform daily tasks. There are two bones in the forearm ...
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 compartment contains three muscles; the biceps brachii, the brachialis and the ...
The mobile wad (or mobile wad of Henry) is a group of the following three muscles found in the lateral compartment of the forearm: [1] brachioradialis; extensor carpi radialis brevis; extensor carpi radialis longus; It is also sometimes known as the "wad of three", [2] "lateral compartment", [3] or "radial group" [4] of the forearm.
The muscles are largely involved with flexion and supination. [2] The superficial muscles have their origin on the common flexor tendon. [2] The ulnar nerve and artery are also contained within this compartment. [2] The flexor digitorum superficialis lies in between the other four muscles of the superficial group and the three muscles of the ...
Most of the large number of muscles in the forearm are divided into the wrist, hand, and finger extensors on the dorsal side (back of hand) and the ditto flexors in the superficial layers on the ventral side (side of palm). These muscles are attached to either the lateral or medial epicondyle of the humerus. They thus act on the elbow, but ...
