  2. Muscles of the thumb - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_the_thumb

    Passing through the first tendon compartment together with the abductor pollicis longus, it is attached to the base of the proximal phalanx of the thumb. It extends the thumb and, because of its close relationship to the long abductor, also abducts the thumb. It is innervated by the deep branch of the radial nerve (C8-T1). [4]

  3. Abductor pollicis brevis muscle - Wikipedia

    en.wikipedia.org/wiki/Abductor_pollicis_brevis...

    The abductor pollicis brevis is a flat, thin muscle located just under the skin. It is a thenar muscle , and therefore contributes to the bulk of the palm's thenar eminence . It originates from the flexor retinaculum of the hand , the tubercle of the scaphoid bone, and additionally sometimes from the tubercle of the trapezium .

  4. Thenar eminence - Wikipedia

    en.wikipedia.org/wiki/Thenar_eminence

    Abductor pollicis brevis abducts the thumb. This muscle is the most superficial of the thenar group. Flexor pollicis brevis, which lies next to the abductor, will flex the thumb, curling it up in the palm. (The flexor pollicis longus, which is inserted into the distal phalanx of the thumb, is not considered part of the thenar eminence.)

  5. Abductor pollicis longus muscle - Wikipedia

    An accessory abductor pollicis longus (AAPL) tendon is present in more than 80% of people, and a separate muscle belly is present in 20% of people. In one study, the accessory tendon was inserted into the trapezium (41%); proximally on the abductor pollicis brevis (22%) and opponens pollicis brevis (5%); had a double insertion on the trapezium and thenar muscles (15%); or the base of the first ...

  6. Muscles of the hand - Wikipedia

    en.wikipedia.org/wiki/Muscles_of_the_hand

    The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...

  7. Recurrent branch of the median nerve - Wikipedia

    en.wikipedia.org/wiki/Recurrent_branch_of_the...

    In the thenar eminence, the recurrent branch of the median nerve provides motor innervation to: [4] opponens pollicis muscle; abductor pollicis brevis muscle; superficial part of flexor pollicis brevis muscle; A separate, more proximal branch of the median nerve additionally provides motor innervation to the 1st and 2nd lumbricals of the hand.

  8. Abductor digiti minimi muscle of the hand - Wikipedia

    en.wikipedia.org/wiki/Abductor_digiti_minimi...

    In human anatomy, the abductor digiti minimi (abductor minimi digiti, abductor digiti quinti, ADM) is a skeletal muscle situated on the ulnar border of the palm of the hand. It forms the ulnar border of the palm and its spindle-like shape defines the hypothenar eminence of the palm together with the skin, connective tissue, and fat surrounding it.

  9. Proper palmar digital nerves of median nerve - Wikipedia

    en.wikipedia.org/wiki/Proper_palmar_digital...

    The lateral portion supplies a short, stout branch to certain of the muscles of the ball of the thumb, viz., the abductor pollicis brevis, the opponens pollicis, and the superficial head of the flexor brevis, and then divides into three proper palmar digital nerves of median nerve (proper volar digital nerves): two of these supply the sides of ...
