Now let's talk about the kind of muscles that you think when you say the word "muscle" - those that show how strong you are and let you shoot on goal and score a goal.
They are the skeletal muscles, also called striated (striated is a word that means a little weird to strip) because the bright and dark bands that make up makes it look as though they are made to strip.
The skeletal muscles are voluntary, meaning that you can control their movement. Your leg did not shoot a ball unless you want to do it.
These muscles are part of the musculoskeletal system - which is composed of the striated muscles and skeleton, or bones. The skeletal muscles are working with the bones to give the body strength and power. In most cases, skeletal muscle of the end of a bone, which is united, covers the bone along its entire length, including the joint (the place where the spindle is joined to another bone) and ends at the end another bone.
The skeletal muscles are attached to bones via tendons. The tendons are a kind of rope made of a fabric resistant muscles and bones that connect with each other. The tendons are so well attached to the bones that, when contracting a muscle, tendon and bone move at a time.
There are skeletal muscles of many different shapes and sizes, allowing them to play many different roles. Some of the larger and more powerful muscles are the ones who got in the back near his spine. These muscles help you keep right and standing. They also give your body the strength it needs to lift and push things.
The muscles that you have in the neck and the upper back are not as great, but they are capable of doing some pretty strange things: try to rotate the head sideways, forward and backward and up and down to notice the strength of the muscles of the neck. These muscles also help you hold your head.
