Fingers do not contain muscles, except for the adductor pollicis and abductor pollicis longus at the base of the thumb. The muscles that move the finger joints are in the palm and forearm. The long tendons that deliver motion from the forearm muscles may be observed to move under the skin at the wrist and on the back of the hand. The muscles that close your hand are known as flexors, and the ones that open your hand are called extensors.

There are no muscles in the fingers, except for the adductor pollicis and abductor pollicis longus at the base of the thumb
While there are no muscles in the fingers, there are two exceptions: the adductor pollicis and abductor pollicis longus, which are found at the base of the thumb. The muscles that move the finger joints are in the palm and forearm. Tendons deliver motion from the forearm muscles, and these can be observed moving under the skin at the wrist and on the back of the hand. Tendons generally connect muscle to bone, while ligaments connect bone to bone. The tendons that control the bones in the fingers are attached to 17 muscles in the palm of the hand and 18 in the forearm.
The muscles that close the hand are known as flexors, while the ones that open the hand are called extensors. Some are small and help control each individual finger. The average grip strength for men aged 20-75 is 104.3 pounds for the right hand and 93.1 pounds for the left. Women averaged 62.8 pounds and 53.9 pounds respectively.
The interosseous muscles are a network of muscles found on and in between the knuckles that enable us to bend the joints in the fingers. The dorsal muscles are used to spread the fingers, while the palmar muscles are used to bend them. There are four dorsal interosseous muscles in each hand. Palmar interossei consist of four muscles each that attach to the first, second, fourth, and fifth fingers.

There are about 30 muscles in the hand, most of which lead to the wrists and forearms. However, there are no muscles in the fingers themselves, except for the adductor pollicis and abductor pollicis longus at the base of the thumb.
