Introduction
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintain posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (Such as the cardiac muscle) can be completely autonomous. We have 600 ~ 700 muscles in our body. Muscles help our body to move.

The Muscular System
There are three types of muscles
Smooth
muscles
Cardiac muscle
s
Skeletal muscle
s
Smooth muscles:We can’t control these muscles. They are divided into two groups:
single-unit muscle and multi-unit muscle. They are
found within the walls of the blood vessel
Cardiac muscles: We can’t control these mus-cles. They are found in the walls and the foun-
dation of the heart, specifically the my-
ocardium.Skeletal muscles: We can control
these muscles. It exists under con-
trol of the somatic nervous system,
that it is voluntary controlled. It is made up of indi-
vidual components known as my-
ocatyes, or "mus-cle cells", some-
times called "mus-cle fibers".
The Muscular System
There are five types of muscles
Pectoral
Triceps
Bicep
Deltoid
Abdominal
Deltoids: in your shouldersPectorals: in your upper chestAbdominals: Near your abdomine(stomach)Biceps: In your upper armsTriceps: In your upper legs
Location of five muscles
Connection of muscles and other body system
How does muscle connect with other body systems???
Muscul-ar system
Skeletal system
Digesti-ve system
Nervous system
Circulat-orysystem
Respira-tory System
Connection of muscles and other body system(2)
Skeletal system
connects with
Muscular system to provide skeletal
movement
Digestive system
connects with
muscular system to
control entrances
and exits of digestive
tracts moves of the food
control digestion of
the food.
Nervous system
connects with
muscular system to
sense things and
produces reflexes
Respiratory system
connects with
Muscular system toAllow the
diaphragm to expend.
Circulatory system
connects with
muscular system to provide
circulation.
Some diseases of problems of muscles
Sometimes, if we exercised too much, muscles become exhausted. There are some problems. Strains and sprains are some when we exercised too much. Strains and sprains are happen when muscles are been stretch too far. It usually happens at your back, neck or legs. We can make our muscles by putting an ice pack. Strains and sprains are different. Strains happen after 5~6 hours. But sprains happen right away.
How we can care our muscular system???
We have to take care our muscles. For our muscles to be healthy, we have to;
-Exercise regularly-Eat healthy food with enough protein-Drink a lot of water-get enough rest or sleep
Muscles grow more and more. When we become adults, we will have strong muscles!!!
Fun facts of muscles
When we write our name, we use about 20mus-cles. When we smile we use about 17muscles. When we frown, we use about 43muscles. We use muscles all the time.
The smallest muscles are in the middle of the ear.
Muscles can account for about 40% your body weight. Muscles can only pull, they cannot, as some people assume, push.
There are 640 individual names for muscles. Muscles need oxygen and food to function prop-erly. The hardest working muscles in the body are the muscles in the eye.
