What is brachioradialis?
Brachioradialis Muscle: Anatomy, Function, and Clinical Relevance Introduction The brachioradialis is a prominent superficial muscle of the forearm that plays a crucial role in elbow flexion , especially when the forearm is in a neutral position . Although it's anatomically located in the posterior (extensor) compartment of the forearm, functionally it behaves like a flexor. Due to its distinct position and function, it is often referred to as the " beer-drinking muscle " because of its engagement in mid-pronated elbow flexion. Understanding the brachioradialis is important for clinicians, physiotherapists, and students involved in rehabilitation, injury prevention, and muscle performance evaluation. Anatomy of the Brachioradialis Origin Lateral supracondylar ridge of the humerus (proximal two-thirds) Insertion Styloid process of the radius Nerve Supply Radial nerve (C5, C6, C7) (Despite being a flexor, it is innervated by the radial nerve, which typically ...
