Explanation:
Tendons are fibrous, thick, stiff and flexible structures, with a whitish color, present in different parts of the human body.
They are part of the striated muscle being made up of connective tissue (composed of collagen).
The main function of the tendons is to connect the muscles to the bones. In this way, it helps in the balance of the body and in the development of movements, distributing the forces in the muscles.
As it pulls the connecting bone with the muscle, the tendon creates the movement in order to transmit the force of the contraction to the bone.
In addition, the tendon provides stability to the joints (meeting point between two bones) of the body's joints.
