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.
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 lateral supracondylar ridge is a prominent, rough margin on the lower part of the lateral border of the humerus.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]
The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow.It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit).
The coracobrachialis muscle muscle in the upper medial part of the arm. It is located within the anterior compartment of the arm.It originates from the coracoid process of the scapula; it inserts onto the middle of the medial aspect of the body of the humerus.
The radial nerve is a nerve in the human body that supplies the posterior portion of the upper limb.It innervates the medial and lateral heads of the triceps brachii muscle of the arm, as well as all 12 muscles in the posterior osteofascial compartment of the forearm and the associated joints and overlying skin.
The radial artery lies superficially in front of the distal end of the radius, between the tendons of the brachioradialis and flexor carpi radialis; it is here that clinician takes the radial pulse. (where it is commonly used to assess the heart rate and cardiac rhythm).
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 anconeus , assisting in extension of the elbow joint, is by some considered part of the posterior compartment of the arm.
