The Flexor Carpi Ulnaris is a muscle located in the forearm. It plays a crucial role in wrist movement, specifically in flexing and adducting the wrist. This muscle originates from the medial epicondyle of the humerus and the olecranon of the ulna, and it inserts into the pisiform bone and the base of the fifth metacarpal. This muscle is innervated by the ulnar nerve, which is responsible for controlling its movements. The Flexor Carpi Ulnaris works alongside other muscles in the forearm to facilitate various hand and wrist actions, making it essential for tasks that require grip and wrist stability.
