Objective:
To learn the
structure and function of the
Skeletal System
Bell Work: Put the terms in
the correct order from most
simple to most complex:
MARROW
SKULL
SKELETAL SYSTEM
OSTEOCYTE

All the bones in your body make up your
skeletal system - has five major functions
1. Shapes and supports body
2. Protects organs
3. Movement
4. Blood cells are made in bone marrow
5. Stores calcium and phosphorus

Bone Structure
1. Periostium: soft thin substance that covers and protects
the bone
2. Compact bone: tough, hard bone that can heal itself
when broken
3. Spongy bone: contains red marrow which makes red
blood cells that carry oxygen and carbon dioxide
throughout the day
4. Marrow: soft, inner center of bones containing blood
vessels and fat cells. Manufactures blood cells

The structure of bones allows for them to
be strong, yet flexible…

Your skeleton begins
as cartilage, which is
gradually broken
down and replaced
with bone which is
why babies have
more bones (300)
than adults (which
have 206).

Joint: any place where two or more bones come
together
Cartilage: rubbery tissue that cushions
bones; located at joints
Ligament: attaches bone to bone

Types of Joints
1. Fixed joint
Allows little movement:
Ex. joints of the bones in
your skull
2. Pivot Joint
One bone rotates around
another bone:
Ex. turning your head;
rotating your wrist

3. Ball-and-socket joint
The ball end of one bone
fits into a cuplike cavity
on another bone.
Ex: Shoulder or hip joint
4. Hinge joint
Back and forth
Ex: knee or elbow joint

5. Sliding joint
One part of a bone
slides over another
bone.
Ex: Bones of wrist or
ankle
