When the muscles start atrophying, the sensory fibers have already been damaged for an extended period of time.Because the thumb is the most mobile of all the fingers, it is susceptible to repetitive movements and overuse.
These thenar mounds are called the thenar eminence and the hypothenar eminence. As its name suggests, it functions as an abductor of the thumb, or moves the thumb away from the hand.All three muscles are innervated by the recurrent branch of the median nerve. The thenar eminence is the fleshy mound at the base of the thumb. Supplies all muscles in anterior forearm except fcu and medial part of fdp; supplies thenar muscles (of thenar eminence - sometimes shared with ulnar nerve) Lumbricals take origin from fdp tendons, share nerve supply of tendon they arise from - medial two lumbricals supplied by ulnar nerve, lateral two supplied by median nerve. Carpal tunnel syndrome occurs when the median nerve, located in the hand, becomes squeezed. The job of this muscle is to flex the thumb, or bend it.The following three muscles are referred to as a group as the thenar eminence.A fourth muscle, called the adductor pollicis is also responsible for fine movements of the thumb, but is not part of the thenar group.
5. Pressure on the median nerve in the carpal tunnel syndrome results when the space within the tunnel decreases in size due to swollen tendon synovial sheaths and/or changes in the osteo-ligamentous elements bordering the tunnel. This nerve supplies finger sensation and muscle function to the thumb, index finger, middle finger, and half of the ring finger. This median nerve originates from a group of nerves called the brachial plexus.Click on the muscles of the thumb to see the opponens pollicis, abductor pollicis brevis, and flexor pollicis brevis.Repeat 10 to 15 times with the same hand and again with the other hand.The opponens pollicis is the largest of the muscles found in the thenar eminence.Pick up a tennis or similar-sized ball in one hand.
