Types Of Muscles In The Human Body

Our today topic is types of muscles in the human body.Muscle is a kind of tissue that has the ability to break and relax. The muscles are composed of fibers floating on each other. These fibers are bridged to each other. When these bridging fibers move, the muscles contract and this contraction also affects the actual movement. Muscles do not grow unless they are pulled by an opposing muscle or an external force.

There are 600 muscles separated from each other in the human body and these muscles are 3 varieties. The heart forms the heart, the smooth muscle is found in the internal organs and around the blood vessels, and the striated muscle is responsible for voluntary movements.

Heart Rate 1.
The heart is a structure that activates its own electrical system, which creates the basic structure of the heart, which allows it to fall independently of the heart. The right upper ear is located at the right ear, and the Sinoatrial node (SA) is located at the right ear. There is a nerve bundle that allows the release of the electrical charge that provides the contraction of the heart. When this electrical impulse is released, it primarily moves around the atria to provide muscle contraction and eventually pumping blood from the ventricles.

In the right ventricle there is the atrioventricular node (AV), which collects the impulses from the SA and another nerve bundle that holds it for a very short time (depending on the heart rate).

As the left ventricle is squeezed, blood is directed towards the aorta (the largest artery in the body), which carries oxygenated blood to the whole body. Right ventricle blood pushes oxygen-free blood through the right pulmonary artery vessels carrying the lungs.

There are atrioventricular valves that prevent blood from flowing back when ventricles contract between the ventricle and the atria. If these valves do not close properly, a problem called heartburn occurs. In some serious cases, a surgical operation is performed to correct the valve or to replace it with an artificial one.

There are also pulmonary and aortic valves that block the blood flow back.

Electrocardiogram (ECG) is a measure of the electrical activity of the heart.

Cardiac output is the amount of blood pumped from the heart in a minute. For an adult at rest, this amount is an average of 5 liters per minute, but for an athlete this may exceed 9.25 liters during running. The cardiac output is determined by the heart rate and the volume of blood that fills the heart chambers. The cardiac output increases as the heart rate increases. However, if the velocity is too high, the cardiac output is reduced because in this case the blood has a very limited time to fill the cardiac atria, so the volume of shot is reduced.

As the carotid arteries exit the left ventricle, they branch off from the aorta. Carotid arteries are responsible for bringing oxygenated blood to the heart muscle. In this way the heart is fed and regular and effective working is ensured. During a heart attack, if one of these carotid arteries is blocked or torn, a certain region of the heart muscle can not get oxygen. This part of the muscle is immediately irreversibly dead, and even a larger area can result in death.

Ischemia (regional anemia) refers to the lack of blood in a specific region of the heart muscle, which in turn leads to the death of touch.

The vital events mentioned above depend on the healthy functioning of your heart muscles. Any problem in the heart muscle can produce serious consequences, which can even lead to death in man.

2- Striped Muscles
Striated muscles have many tasks such as protecting organs and providing movement. These muscles work directly by receiving a signal from the brain. In stressful situations such as weight gain, striped muscles become stronger and larger. But when they are used less, they become weaker and smaller.

Unlike other cells in the body, the ability of cells to divide and regenerate is very limited. But the satellite cells embedded in the fibers may break up to form new cells in some cases, but they can not restore the heavily damaged part and can not contribute to the increase in muscle strength during exercise.

Muscle work does not create more cells, but these cells grow over time. There are 3 types of striated muscles:

Slow Oxidative Fibers

These muscles are the most durable and the smallest in volume. These muscles are the slowest, but the longest is the longest.

Fast Oxidative Fibers

These muscles are medium strength and large.

Fast Glycolytic Fibers

These muscles are the thickest and strongest, but the fastest tired muscles. These muscles contract very quickly, but it can not last a long time.

For example, one that is dominant in slow oxidative fibers is a runner in high endurance. One that is dominant in fast glycolytic fibers can be a very good short distance runner. But training is an important influence.

Muscles are metabolically active and require high amounts of energy even at rest. Unconscious people who lose weight increase muscle loss as you burn calories.

Muscles are very flexible and connect to bones with very strong and inflexible tissues called tendons.

3- Plain Muscles
Smooth muscles work completely inadvertently and contractions can not be controlled. Smooth muscles are found around the internal organs (such as the stomach and urine bag) and allow these organs to contract. For example, the muscles in the intestines and in the food pipe allow the food to progress.

Smooth muscles have the ability to divide unlike striped muscles. It also has more flexibility.
