Are There muscles in your fingers? If You were curious about this question, We are glad you at the right page.

Extreme sports professionals are often recommended to practice exercises to “strengthen their fingers.”

As everyone already knows, the common idea of strengthening is to exercise and watch your muscles grow.

However, in human hands, this is not quite how the process works.

Amazingly, the fingers of the human hand have no muscles. None of the ten fingers in hands have strengths but are made up solely of bones, ligaments, and tendons, as shown in the figure below.

So, How Do We Move Our Fingers? Are there muscles in your fingers or is it in somewhere else?

If you look at a person’s arm, you may have seen their muscles. Without muscles, human beings cannot freely move the bones of the hands, feet, and other parts.

Well, what about the fingers? Have you ever seen a person’s fingers have muscles?

No! so how do the fingers move is the question that might arise in your mind.

For sure, the fingers have no muscles, but they can still work well. There are no muscles in the fingers, and there are 34 muscles in the palms and forearms from the elbows to the wrists that make the fingers work correctly.

These muscles make the fingers do several things. For example, they are opening a door, clapping, pointing with your fingers, shaking hands, holding a purse, touching your cell phone, and several others.

The fingers and palms have a very complicated structure. Each hand has 27 bones and several joints.

The total amount of bones in the hands makes up almost a quarter of the total number of bones in the human body.

How can humans type, play the piano and do things with their fingers? Everything centers on the brain.

Muscles in the palms and forearms only work when the brain tells them to do so.

About a quarter of the brain controls the hand muscles’ movement to move the fingers.

Ligaments connect the different bones of the finger and the joints between them, while tendons connect these structures of bones and ligaments with the forearm’s muscles (fingers) and with forces of the palm and back of the hand.

These forearm muscles and the palms are responsible for the fingers’ movement; their contraction and distention pull and loosen the tendons that attach to the fingers’ bones and thus produce a signal.

The brain sends messages to the nerves that are connected to the muscles in the palms and forearms.

Therefore, the brain commands the nerves in the palm to move the fingers’ tendons and bones.

The muscles that move the fingers can classify into two large groups:

Short muscles of the hand connected fingers (or foot):

They insert and originate in the hand or foot and provide very high precision to the fingers’ movements.

They are also referring to as “intrinsic muscles of the hand.” 

For example, in hand, we have the opposing muscle of the little finger, the Flexor Digitorum Brevis muscle of the little finger, the opposing power of the thumb, or the palmar cutaneous muscle. 

Long muscles in fingers

They do not originate in the hand or foot but insert into them.

Those provide more abrupt, general, and less precise movements. They are located on the forearm, for the fingers, or on the calf, for the toes.

Those also known as “extrinsic muscles of the hand”—for example, the fingers’ deep joint flexor muscle.

Which nerves are connected to your hand to move the fingers?


There are two primary nerves for moving the fingers, the median nerve and the ulnar nerve.

The median nerve points to the thumb, index finger, middle finger, and part of the ring finger.

In contrast, the ulnar nerve is the nerve that carries messages from the brain to move the little finger and half of the ring finger.

Moreover, the radial nerve provides sensation to the backside of the thumb. Here is a picture of the hand and the nerves responsible for transmitting the message.

Nerves In The Hand

For example, to move your little finger, your brain will send a message to the ulnar nerve, and the ulnar nerve will cause the palm muscles to contract so that the tendons move the little finger.

How do your fingers’ joints move?

Each finger of yours can move, even if it does not move widely in all directions. Each finger has three bones, except the thumb, which has only two bones.

Between these bones, there are joints. This joint makes the fingers move, and it can do so only in one way, namely, flexion and extension. It means that the fingers can only move to bend and straighten again.

If you move your finger, you can bend it in one direction and return it straight, right? Now, this is what it means to bend and straighten.

More facts about fingers

  • For each hand, there are a total of 19 muscles that provide movement to the fingers, including intrinsic and extrinsic muscles.
  • The skin on the fingertips has many more nerve endings than any other part of the body, making it the area where the sense of touch is most sensitive.
  • On average, women have longer index fingers, and men have ring fingers.


In conclusion, Are there muscles in your fingers?

we can say that the fingers have no muscles; thereby, your fingers’ movement works by tendons and ligaments.

The tendons that control your fingers’ bones connect to no less than 34 muscles present in the palm and forearm.

These muscles are responsible for the movement of fingers with the help of tendons and ligaments. In the human body, the hand is one of the most intricate and beautiful natural engineering pieces
