What are all tendons in the human hand?
The following are the tendons found in the human hand:
Flexor tendons:
* Flexor carpi radialis tendon: This tendon originates from the flexor carpi radialis muscle in the forearm and inserts into the base of the second metacarpal bone in the hand. It helps to flex the wrist and the hand.
* Flexor carpi ulnaris tendon: This tendon originates from the flexor carpi ulnaris muscle in the forearm and inserts into the pisiform bone and the base of the fifth metacarpal bone in the hand. It helps to flex the wrist and the hand.
* Flexor digitorum superficialis tendons: These tendons originate from the flexor digitorum superficialis muscle in the forearm and insert into the middle phalanges of the fingers. They help to flex the fingers.
* Flexor digitorum profundus tendons: These tendons originate from the flexor digitorum profundus muscle in the forearm and insert into the distal phalanges of the fingers. They help to flex the fingers.
* Flexor pollicis longus tendon: This tendon originates from the flexor pollicis longus muscle in the forearm and inserts into the base of the distal phalanx of the thumb. It helps to flex the thumb.
Extensor tendons:
* Extensor carpi radialis longus tendon: This tendon originates from the extensor carpi radialis longus muscle in the forearm and inserts into the base of the second metacarpal bone in the hand. It helps to extend the wrist and the hand.
* Extensor carpi radialis brevis tendon: This tendon originates from the extensor carpi radialis brevis muscle in the forearm and inserts into the base of the third metacarpal bone in the hand. It helps to extend the wrist and the hand.
* Extensor carpi ulnaris tendon: This tendon originates from the extensor carpi ulnaris muscle in the forearm and inserts into the base of the fifth metacarpal bone in the hand. It helps to extend the wrist and the hand.
* Extensor digitorum tendons: These tendons originate from the extensor digitorum muscle in the forearm and insert into the bases of the distal phalanges of the fingers. They help to extend the fingers.
* Extensor pollicis longus tendon: This tendon originates from the extensor pollicis longus muscle in the forearm and inserts into the base of the distal phalanx of the thumb. It helps to extend the thumb.
In addition to these main tendons, there are also a number of smaller tendons that help to control the movement of the fingers and the thumb.
