Marrow – In the center of some
bones.
Joints – Points at which bones meet
Cartilage – Flexi able tissue that
provides cushioning at your joints
Ligaments – Tissue that hold bones in
place
Tendons – Tough bands of tissue that
attaches your muscle to bone
Skeleton system – Internal system
that make up of bones, joints, and
connective tissue
Bones
► There
are 206 bones in the human body.
► Bone do the following:
1. Allow movement.
2. Provide support
3. Protect other parts of your body.
4. Makes new blood cells.
5. Stores minerals
Connective
Tissues
Cartilage –Allows
joints to move
easily, cushions
bones, and supports
soft tissue
Ligament –Hold
bones in place at the
joints
Tendon –Joins
muscle to muscle or
muscle to bone
Types of Bones
Short Bone
As wide as they are long
Irregular Bone
Flat Bone
Provides Protection
bones which do not fall into any other
category

There are four different
joint in the human body.
Hinge – moves in one
direction.
Gliding – enable bones
to slide over one another
Pivot – move from side
to side.
Ball and Socket –
Moves in all direction,
allowing rotation.
Can you name the joint in
your thumb?
Problems with Skeletal System
► Fracture
– break in the bone
► Dislocation – bone is pushed out of the joint.
► Sprain – stretching of the ligament.
► Osteoarthritis – break down of cartilage.
► Scoliosis – Spine is in an sideways curvature.
► Osteoporosis – brittle bones (lack of vitamin D
and exercise.)
Care for the Skeleton system.
► Physically
active
► Eat health foods high in calcium, low in
phosphorus.
► Sit, stand with straight posture.
► Wear good shoes.

Types of Breaks
There are 6 different types
of breaks to the bones.
Closed fracture – Bone is not
sticking out of the body.
Open fracture – when the bone
is sticking out of the body.
Multiple fracture – a fracture
break that extends several fracture
lines in one bone, and the fracture
of several bones at one time or
from the same injury.
Greenstick fracture – Break in a
young bone . The bone bends.
Comminuted fracture - A
fracture in which the bone has
broken into a number of pieces
Spiral fracture – Break goes
around the bone.
WILT
► Finish
the following pages from the
workbook. Your head bones and Sticks
and stones may break your bones is
homework.
► Write a page on the bones in the human
body. Function, how they work, and why
we need bones.
► We will review next class.
