Muscles are the tissues responsible for the movement of the living body. Many biological processes take place in muscles. based on that, we can answer the above questions as follows:
- The isometric contraction is a muscle tension that occurs in the muscle, even though this muscle does not need to be tensioned to move any load.
- Muscle tone occurs when the muscle is tense, even at rest. This happens through the control of the nervous system, due to the alternating motor units of a muscular organ.
- Tetanus is a muscle contraction that occurs through rapid muscle stimulation. This contraction is very mild and can occur without the individual's awareness.
- Isotonic contraction is a process of shortening the muscle. This process is not something positive, most of the time, and occurs when muscle tension is greater than the load that is stimulating the muscle.
- The multiple motor unit summation is the term used to explain how the increase in muscle strength occurs gradually.
