The flexor carpi radialis is the most lateral forearm flexor muscle, innervated by the median nerve, and it abducts and flexes the wrist.

Step-by-step explanation:

The muscle described in the question is the flexor carpi radialis. This muscle is the most lateral of the flexor muscles in the forearm, originating at the medial epicondyle of the humerus and inserting on the bases of the second and third metacarpals. It is innervated by the median nerve and is responsible for abducting and flexing the wrist. The flexor carpi radialis muscle is crucial for movements such as gripping and wrist manipulation, contributing to various hand functions necessary for everyday activities and specialized tasks like typing or playing instruments.
