Brachioradialis Muscle
The Brachioradialis muscle (pronunciation: bray-key-oh-ray-dee-ah-lis) is a muscle of the forearm that flexes the forearm at the elbow. It is also capable of both pronation and supination, depending on the position of the forearm. It is attached to the distal styloid process of the radius and along the midshaft of the humerus.
Etymology
The term "Brachioradialis" comes from the Latin brachium meaning "arm", and radius meaning "ray". In this context, it refers to the radius bone of the forearm.
Function
The primary function of the Brachioradialis muscle is to flex the forearm at the elbow. It is also capable of mid-pronation and mid-supination, which means it can rotate the forearm to an intermediate position.
Clinical Significance
The Brachioradialis muscle is often used as a landmark for healthcare professionals during procedures such as intravenous therapy. It is also the muscle tested by the Brachioradialis reflex test, a common test used in neurological examinations.
