Слайд 3 5 Functions of the Skeletal System
1. Movement: Skeletal

5 Functions of the Skeletal System1. Movement: Skeletal system provides points

system provides points of attachment for muscles. Your legs

and arms move when the muscles pull on the bones.


2. Support: The backbone is the main support center for the upper body. It holds your head up and protects your spinal cord.

Muscle attached to bones!!

3. Protection: The

5 Functions of the Skeletal System3. Protection: The bones of your

bones of your skull protect your brain. Your ribs

protect your lungs and heart from injury.

4. Makes Blood: Red and white blood cells are formed by tissue called marrow, which is in the center of the bone.

5. Storage: Bones

5 Functions of the Skeletal System5. Storage: Bones store minerals, such

store minerals, such as calcium and phosphorus, for use

by the body



Слайд 6 Two Major Skeletal System Parts
Axial Skeleton: The axial

Two Major Skeletal System PartsAxial Skeleton: The axial skeleton includes the

skeleton includes the skull, spine, ribs and sternum.

Appendicular

Skeleton: The appendicular skeleton includes the appendages of the body, which are the shoulders, arms, hips, and legs.

Слайд 8 Bone Structure
Typical Four Layers:
Periosteum: Covers Bones
Compact Bone: Lies

Слайд 12 Clavicle or Collarbone
The clavicle, or collar bone, holds

Clavicle or CollarboneThe clavicle, or collar bone, holds the shoulder joint

the shoulder joint away from the rest of the

upper body and is only as thick as your little finger.



Слайд 13 Scapula
The scapula is located on the back side

ScapulaThe scapula is located on the back side of the ribcage

of the ribcage and helps provide part of the

shoulder joint and movement for the arms.
