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.
Thus the elbow is distal to a wound on the upper arm, but proximal to a wound on the lower arm. [30] The terms are also applied to internal anatomy, such as to the reproductive tract of snails. Unfortunately, different authors use the terms in opposite senses.
The deep muscles arise from the distal part of the ulna and the surrounding interosseous membrane. The brachioradialis , flexor of the elbow , is unusual in that it is located in the posterior compartment, but it is actually a muscle of flexor / anterior compartment of the forearm.
The distal part of the upper limb between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand. By anatomical definitions, the bones , ligaments and skeletal muscles of the shoulder girdle , as well as the axilla between them, are considered parts of the upper ...
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 ...
The distal end of the radius forms two palpable points, radially the styloid process and Lister's tubercle on the ulnar side. Along with the proximal and distal radioulnar articulations , an interosseous membrane originates medially along the length of the body of the radius to attach the radius to the ulna.
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 distal radioulnar articulation [1] (also known as the distal radioulnar joint, [2] or inferior radioulnar joint [1] [3]) is a synovial pivot joint between the two bones in the forearm; the radius and ulna. It is one of two joints between the radius and ulna, the other being the proximal radioulnar articulation.
