It flexes and adducts the thumb (brings it across the palm) and is controlled by the median nerve. The mechanics behind this (greatly simplified) relate to the different angles of attachment of the IR and SO; this is also the reason behind the IR and SO being restricted to depressing the eye during adbuction and adduction, respectively. Abdominal wall muscle. This is because your eyes are rotating in the opposite direction of head movement (i.e., the VOR) to maintain stability of the image in front of you.
