Janet Baity
The 5 Functions:
1. Skeleton gives us structure and support
2. Skeleton protects the internal organs
3. Skeleton provides a place for muscles to attach
4. Red blood cells are made inside bones in
tissue called marrow
5. Skeleton stores compounds such as calcium
and phosphorus
Structure and Support
Protection
Parts of Bone
1. Periosteum
2. Compact (hard bone)
3.Cancellous (spongy) bone
4. Bone marrow

Draw the bone and label the
parts
206 bones make up your
skeleton system. Bones
contain minerals such as
calcium and phosphorus.
These help give bones their
strength.
Muscles attach to the skeleton
The_Muscular_System.asf
Muscle Action in the Skeletal System
Working in opposing pairs,
muscles serve to move the bones.
Bones are connected to muscles by
thick bands of connective tissue,
known as tendons. When muscles
contract (become shorter) and
relax ( become longer), they pull
on the bones making movement
occur.
