2. smooth muscle
3. cardiac muscle
This is the outer layer of the skin, made up of cells that live for about 2 weeks.

True or False: muscle cells can both extend and contract.
False - muscle cells can only contract.
This substance is a pigment produced in the epidermis and gives skin its color.
What is melanin?
Describe how the muscles and bones work together to facilitate movement in our body.
What is: paired muscles work together when one contracts while the other relaxes to move in one direction, then the other muscle contracts while the other relaxes to move in the other direction.
Name the five functions of the skeleton.
What are:
1. provide shape and support
2. enables you to move
3. protects organs
4. produces blood cells
5. stores minerals
Name two ways to prevent skeletal injuries.
What are:
1. warming up before exercising
2. wearing appropriate protective equipment
3. exercising in safe places
Give an example of a voluntary muscle and an involuntary muscle.
voluntary: leg muscles, face muscles, arm muscles, any skeletal muscle
involuntary: heart muscle, muscles in digestion
Give 4 of the 7 functions of the skin.
What are:
1. provides covering
2. prevents loss of water
3. protects from injury and infection
4. regulates body temperature
5. eliminates wastes
6. gathers information about the environment
7. produces vitamin D
Name 4 habits to help you keep your skin healthy.
