What is the muscular system?

It includes muscles and tendons that connect muscle to bones. It allows you to move.

18

Skeletal Muscle

  • Support and move the body

  • voluntary muscles - you control them.

  • Ex: Leg muscles

media

19

Involuntary Muscles

(You Can't Control Them)

  • smooth muscle - makes up most of the walls of the body’s organs,

    including blood vessels and digestive organs.

  • cardiac muscle - makes up the walls of the heart.

Bones & Muscles

Your skeleton helps your body move. Bones can’t stretch or bend on their own. The parts around them help them move a little bit, though. Your bones are covered by muscles. Muscles are attached to your bones by tendons. Tendons are like elastic bands. They let your

muscles move away from your bones and then back again. Flexible bands called joints connect each bone. Joints let your bones move back and forth.


FAST FACT: When you break a bone, your body can rebuild it. Bones are made of cells. When a bone is broken, extra cells are made. The extra cells cover each end of the broken bone. Eventually, the bone will close back up.

Types of Bones

There are four types of bones. Long bones make up bigger body parts. Your arms and legs are long bones. Short bones are found in places like your hands and feet. Flat bones are flat. They make up body parts like your skull and ribs. Sesamoid bones cover strangely shaped places. Your kneecap and the ball of your foot are two examples of this type of bone.

Bones Have a Job!

Your skull, your spine, and your rib cage are three very important bones. They protect important organs. Your skull protects your brain. It also shapes your face. Your spine has 26 bones. It lets you stand, sit, and turn your body. Your rib cage protects your lungs, heart, and other organs. Your rib cage is made up of twelve ribs. Your ribs attach to your spine.


FAST FACT: The smallest bone in your body is the stirrup bone. It is located inside your ear. The longest bone in your body is the femur. It is a leg bone that connects your hip to your knee.

How Muscles Work

Muscles work by expanding and contracting. Expanding means to stretch out.  Contracting means to shrink back in. When muscles expand or relax, the fiber bundles slide  apart. This makes the muscle longer. When muscles contract, the fibers slide together. They form a stacked shape. Every muscle works in a pair with a partner. When one muscle contracts, the other will relax.

Types of Muscles

There are three types of muscles. Skeletal muscles allow your body to move, and they  also give you power and strength. Skeletal muscles cover bones all over your body. They help  you control your movements. Smooth muscles are layered muscles that are totally controlled  by your brain. They control organs in your body like your lungs. Cardiac muscles are in your heart. They work to pump blood around your body.  Smooth and cardiac muscles are  called involuntary muscles. Your body keeps  them moving without you having to tell it to. For example, involuntary muscles control your  

breathing and heart beating. Skeletal muscles are called voluntary muscles. You have to tell  them what to do. For example, voluntary muscles allow you to run and jump.
