Skeleton Basics
This is the main function of the skeleton that gives the body shape
Support
The skull protects this organ.
Brain
This softer tissue reduces friction at joints. Has a glossy appearance.
Cartilage
Muscles attached to bones are called this type.
skeletal muscles
A joint is where this happens.
where two bones meet
The skeleton has these two main divisions.
Axial and Appendicular skeleton
These fixed joints join skull bones together
Sutures
Strong fibres that join muscle to bone.
Tendons
Muscles work in these pairs to move bones.
antagonistic pairs
The shoulder is what type of joint
ball and socket
This mineral stored in bones helps keep them strong.
Calcium

33
Elastic bands joining bone to bone.
Ligaments
When the biceps contract, this muscle relaxes.
Triceps
The elbow is what type of joint
hinge joint
The skeleton made blood cells in this part of the bone.
Red bone marrow
These discs between vertebrae absorb shock and are made from ______.
Cartilage
This type of bone makes bones strong and dense.
compact bone
This type of muscle never tires and is found in the heart.
cardiac muscle
This girdle supports the legs and protects lower organs.
Pelvic Girdle
This part of the skeleton includes the skull, ribs, and vertebral column.
Axial skeleton
These ribs do not attach to the sternum.
Floating Ribs
This marrow stores fat instead of producing blood cells.
Yellow marrow.
Movement happens because muscles can only do this action to bones.
pull (contract)
This fluid lubricates movable joints.
Synovial fluid
