<h3><u>Connective tissue:</u></h3>

It is the layer under the epithelial tissue in the body. It is stronger than epithelial tissue and is found in many organs. It provides protection.

<h3><u>Epithelial tissue:</u></h3>

It covers the outside of the body like a veil. located in the outermost part of the body. Protects the body against microbes and infections.

<h3><u>Muscle tissue:</u></h3>

It is located in the joint areas and forms the support and movement system. It allows us to make bodily movements.

<h3><u>Nervous tissue:</u></h3>

It is the fastest communication tissue. It allows us to feel pain and the sense of touch. It is impossible to repair this tissue after it is damaged. It causes paralysis. It is very important as it plays a role in the activity of neural transmission.

In order to predict how much tension a muscle can produce when contracting, it is important to consider the ______ relationship

serg [7]

The muscles are composed inside mainly of fibers, filaments and proteins, where it is important to consider the <u>length-tension</u> relationship of the thick and thin filaments to know the tension.

<h3>What is muscle contraction?</h3>

It is an organized and natural event that takes place at the level of the muscles when the fibers and proteins inside them come together, and tension is produced in the area.

<h3>Characteristics of muscle contraction</h3>

In a muscle contraction, a tension is generated that depends on the length-tension relationship, which causes a displacement of the muscle filaments.

The proteins actin and myosin join together, and a force is generated so that the final movement is achieved.

To know the tension, the muscle changes length and measurable external work is produced from the force and distance traveled.

Therefore, we can conclude that the contraction allows us to make movements to reach and carry our extremities to different places.
