Pinky finger

The pinky finger is the fifth digit of the hand and is the least often used of the five fingers. As the smallest digit, the pinky is located next to the ring finger. In comparison to other fingers, the pinky possesses the most diminished range of motion. The finger is controlled by a group of muscles that includes the fourth lumbrical and the extensor digiti minimi. Also, the muscles of the hypothenar eminence assist the pinky, and those muscles include the abductor minimi digiti, the opponens digiti minimi and the flexor digiti minimi. These muscles are supplied oxygenated blood by the ulnar artery and the ulnar nerve innervates them. The little finger's bones consist of the three types of phalanges. The pinky finger contains a proximal phalange jointed to a metacarpal. The proximal is jointed to the distal phalange at the end, which is the bone of the fingertip. The distal phalange is also the skeletal support for the pinky's fingernail, as well as the sensitive mass of tissue making up the fingertip.
