This type of muscle forms the wall of the heart.
What is cardiac muscle?
These two organs make up the central nervous system.
What are the brain and spinal cord?
A band of fibrous, slightly elastic connective tissue that attaches one bone to another.
What is a ligament?
A disease that causes progressive loss of bone tissue and makes bones brittle.
What is osteoporosis?
A hinge joint allows this kind of movement; give an example.
