Fingers don't contain muscles to facilitate movement, but they can still move thanks to the tendons and muscles in our palms and forearms. When we want to flex or extend our fingers, the tendons connected to the muscles pull on the bones in our fingers, causing them to move. The two major actions of fingers – flexing and extending – are carried out by flexor and extensor muscles, respectively.

Tendons, bones and muscles in the palms of our hands work together to move our fingers
Although fingers don't contain muscles, they are still able to move due to the tendons, bones and muscles in the palms of our hands working together. Tendons connect muscles to bones, and when a muscle contracts, it pulls on a tendon. Tendons are connected to muscles on one end and bones on the other, so when a tendon is pulled, it causes a bone to move. The two major actions of fingers – flexing and extending – are carried out by flexor and extensor muscles, respectively. These muscles are present in the palm and forearm, and they control the movement of our fingers. When we want to flex or extend our fingers, the tendons connected to the muscles pull on the bones in our fingers, causing them to move.

Tendons are connected to muscles on one end and bones on the other
Although fingers don't contain muscles, they are able to move because of the tendons that are connected to the muscles in the palms and forearms. Tendons are connected to muscles on one end and bones on the other, so when a muscle contracts, it pulls on a tendon, which in turn pulls on a bone, causing it to move. This is how the movement of the fingers is controlled. The two major actions of fingers – flexing and extending – are carried out by flexor and extensor muscles, respectively.
Tendons are essential for the movement of fingers, as they transmit the force generated by muscles to the bones. When a muscle contracts, it pulls on the tendon, which then pulls on the bone, causing it to move. This process is known as muscle contraction and is responsible for the movement of all body parts, not just the fingers.
The human hand is a complex structure, containing a total of 27 bones, which is almost one-quarter of all the bones in the human body. The fingers themselves contain no muscles that control movement, but the tendons, bones and muscles in the palms and forearms work together to allow the fingers to move.
The tendons that help in the movement of fingers are attached to 17 muscles in the palm and 18 muscles in the forearm. These muscles and tendons work together to allow the fingers to perform a wide range of actions, such as gripping an object, lifting a weight or pointing at something.

The two major actions of fingers are flexing and extending
Fingers do not contain muscles to facilitate movement. However, it is important to note that muscles are still involved in the movement of fingers. The movement of fingers is made possible by the concerted actions of tendons, bones, and muscles present in the palms of our hands.

Fingers don't contain muscles that control movement
The human hand is a very complex structure. It contains a total of 27 bones, which means that almost one-quarter of all the bones in the human body are found in our two hands. The only muscles fingers have are tiny arrector pili muscles that help make the hair on your fingers stand out.

The muscles in our palms and forearms control the movement of our fingers
It's a common misconception that fingers don't contain any muscles. In fact, fingers do have muscles, but they are completely unrelated to motion. Instead, the muscles in our palms and forearms control the movement of our fingers. When we want to flex or extend our fingers, the tendons connected to the muscles pull on the bones in our fingers, causing them to move.

The two major actions of fingers – flexing and extending – are carried out by flexor and extensor muscles, respectively.
When a muscle contracts, a tendon is pulled. Tendons are connected to muscles on one end and bones on the other, so a pulled tendon causes a bone to move and perform specific actions. For example, when you want to point a finger at something, the tendons pull on the bones in the index finger, which become taut. Every kind of possible action that fingers perform is controlled or regulated by muscles present in the palm and forearm. This is why you can so strongly ''feel' those muscles when you grip something tightly or lift something heavy.
Fingers may not have muscles of their own, but thanks to the pudgy palm and the firm forearm, they certainly never feel the pang of their absence.
