The flexor carpi radialis is a muscle located in the forearm. It plays a crucial role in wrist movement, specifically in flexing the wrist and aiding in the abduction of the hand. This muscle originates from the medial epicondyle of the humerus and attaches to the base of the second and third metacarpal bones. This muscle is innervated by the median nerve, which is responsible for transmitting signals that control muscle movement. The flexor carpi radialis works in conjunction with other muscles in the forearm to facilitate various hand and wrist actions, making it essential for daily activities like gripping and lifting.
