The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. [1] [2] It is also capable of both pronation and supination, depending on the position of the forearm. [2] It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and to the lateral supracondylar ridge of the humerus.
Meaning Origin language and etymology Example(s) quadr(i)-four Latin quattuor: quadriceps: radi-radiation Latin radiō, I radiate, emit beams; from radius, ray of light, spoke of a wheel radiowave: radic-referring to the beginning, or the root, of a structure, usually a nerve or a vein Latin rādīx, root radiculopathy: re-again, back Latin re ...
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
The root of a term often refers to an organ or tissue. For example, the Latin name musculus biceps brachii can be broken down: musculus meaning muscle, biceps meaning "two-headed", and brachii referring to the arm (brachial region). The first term identifies the structure, the second indicates the type or instance of the structure, and the ...
This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes. The meaning of terms that are used can change depending on whether an organism is bipedal or quadrupedal.
It presents an anterior lip for the origin of forearm extensors, including the brachioradialis muscle above, and the extensor carpi radialis longus muscle below. [1] It also presents a posterior lip for the triceps brachii , and an intermediate ridge for the attachment of the lateral intermuscular septum .
The posterior muscular branch, of large size, arises from the nerve in the groove between the triceps brachii and the humerus. It divides into filaments, which supply the medial and lateral heads of the triceps brachii and the anconæus muscles.
One of the three muscles of the radial forearm group, it initially lies beside the brachioradialis, but becomes mostly tendon early on. Passing between the brachioradialis and the extensor carpi radialis brevis, this tendon continues into the second tendon compartment together with the latter muscle. [2]
