We Have No Muscles in Our Fingers! So How Does It Move?

It seems weird that we don’t have muscles in our fingers, doesn’t it? of this situation There is plenty of scientific evidence that it stems from our evolution. And when you learn why this is the case, it will make perfect sense to you.

Let’s see Our fingers, one of the most important parts of our body equipped with muscles, What is the reason for not having muscle?

Our ancestors were tree-dwelling primates.

As you know, ancient primates lived in trees. That’s why it had long fingers to move from place to place. Because he had tendons in his fingers back then Considering their movements in living spaces this was necessary.

12,000 years ago people; As they transitioned to a sedentary lifestyle, they used their hands for agriculture, hunting, or other activities from ancient primates. in more different ways They started using it. The lack of muscles in their fingers allowed them to perform more delicate and fine tasks more easily.

In short, the fact that we do not have muscles in our fingers, like many other features, stems from our evolutionary past.

So, if our fingers don’t have muscles, how do they move?

There are no muscles in our fingers other than the APM muscle, which is connected to the hair follicles and causes the hair to stand upright when contracted. Instead of; tendons, bones and muscles in our palms harmonious movements there is.

For example, when we point our finger in a direction, the brain sends a message/electrical impulse through the nerves connecting to the muscles in the palm and forearm. This impulse affects certain muscles command to relax and others to stretch/squeeze gives. When the muscle contracts, the tendon pulls.

Since tendons are connected to muscles at one end and bones at the other end, the pulled tendon; allowing the bone to move. In short, the movements we make with our fingers; It is controlled by the muscles in the palm and forearm. Thus, we can feel the muscles when we hold something tightly or lift something heavy.
