Muscles
• Many of these are attached to bones and help you to move.
Cardiac
• The heart is this kind of muscle.
• This muscle never gets tired or sore like your leg muscles do.
• It is an involuntary muscle that controls the heart.
Voluntary Muscles
• You can contract and relax this in order to move body parts.
• Another name for Skeletal Muscles
• Flexing your biceps, chewing, running, and jumping are examples of this.
Skeletal
• This system is made up of over 22 bones!
• This system provides the framework for your body.
• We are born with 300 bones.
What is the Skeletal System?
• The Skeletal System is all of our bones
• It is the frame of our body
• Without bones, we would be floppy
• Some bones protect our fragile insides. Our skull protects our brain and our ribs protect our lungs, heart, and other insides
How Many Bones Do Humans Have?
• Humans are born with 300 bones
• As we grow our bones fuse, or grow together
• Adults have 206 bones
Are Bones Alive?
• Yes!
• Bones are made of hard stuff for strength and living cells to help them grow and repair themselves
How Do Bones Move?• Bones need muscles to help them move
• Joints are the place where two bones meet allowing them to move
• Our elbows, shoulders, knees, neck, and hips are joints
Cranium
• This is the part of the skull that protects your brain.
• It is the top part of your skull.
Bone Marrow
• This is where red blood cells are made.
• This is a soft jelly-like material that fills the inside of our bones.
Involuntary Muscles
• These are muscles that we do not control.
• Breathing
• This kind of muscle is also called a smooth muscle.
Compact Bone
• This is the hard outer part of the bone.
Spongy Bone
• The inner part of the bone
Ligaments
• These connect bones to other bones
• These connect one vertebrae to another
Tendon
• This connects muscles to bones
• This is the part that is named after Achilles
Cartilage• This is like a shock absorber for our bones
• This is what cushions the bones in your spinal column
• This is what the tip of your nose is made of
Vertebrae• There are 24
stacked on top of one another to make up the spinal column
• They are smaller in your neck than in your back
• There is one fused together in your spinal column called your tail bone
The Brain
• The brain is made up of the cerebrum, cerebellum, and medulla.
• The largest part of the brain is the cerebrum.
• The medulla is connected to our spinal cord. It controls blood circulation and breathing.
• The cerebellum controls our balance and posture.
X-Rays
• X-rays are special pictures of our skeletal system.
• These pictures help us to see the inside frame of our bodies.
