Brachioradials

The brachioradialis muscle is a superficial muscle that occupies the lateral region of the forearm and is clearly visible in normal-weight people.

It originates on the lateral supracondylar ridge of the humerus (under the groove of the radial nerve) and on the lateral intermuscular septum.

It fits into the radial face of the radium styloid process. It is a monoarticular muscle that brings the forearm into an intermediate position between pronation and supination. In this position he is a powerful flexor of the elbow. Therefore it intervenes in movements such as the curl with a "hammer" grip to train the forearms and in lifting for the handle of a mug of beer (with the hand parallel to the median plane). Its flexor action is instead weak if the forearm is in supination. Excluding from a purely anatomical context, this muscle is particularly developed in the comic book character called Popeye and known in Italy as Braccio di ferro (ops ... forearm)!

It is innervated by the radial nerve (C5-C6).
