Do fingers have tendons or ligaments?
Fingers are constructed of ligaments (strong supportive tissue connecting bone to bone), tendons (attachment tissue from muscle to bone), and three phalanges (bones). There are no muscles in the fingers; and fingers move by the pull of forearm muscles on the tendons. The thumb does not have a middle phalange.
