400

The tissue connective tissue that connects bones to bones. 

Ligament

500

Name the five functions of the bones.

provide shape and support, enables you to move, protects organs, produces blood cells, stores minerals

Muscles

100

What is the connective tissue between bones and muscles?

tendon

200

Muscle tissue ________________ to make body parts move.

contracts

300

How do pairs of muscles work together? Explain how this works in the arm.

While one muscle in the pair contracts, the other relaxes. The biceps contracts and bends the arm, while the triceps relaxes. The triceps contracts and straightens the arm while the biceps relaxes.

400

Which type of muscle tires quickly during exercise? Name the other two types of muscle, and give examples of where the muscles exist in the body.

skeletal - attached to bones, cardiac - heart, smooth - inside of organs like intestines

500

Explain the difference between voluntary and involuntary muscles. What type of muscle belongs to each.

Muscles under our conscious control are voluntary. Those not under our conscious control are involuntary. Voluntary - skeletal. Involuntary - smooth, cardiac

Skin

100

True or False: Most of your surface skin are actually dead skin cells. 

True

200

How does the skin help regulate body temperature? a. by removing wastes from the body b. by blocking information about the environment c. by enabling excess heat to escape from the body d. by allowing body temperature to change when the weather becomes warmer or cooler

c

300

How does the skin protect the body from disease? a. by keeping disease-causing microorganisms from entering the body b. by gathering information about the environment c. by increasing body temperature when it is cold d. by supplying water to the body through the pores

b

400

Describe the structure of the layers of the skin.

epidermis is where new skin cells form and move toward the surface, hair and pores come through this layer. Dermis contains blood vessels, sweat and oil glands, fat, and nerves.

500

List the five functions of the skin.

protects the body, regulate body temperature, eliminate wastes, gathers information, produce vitamin D.

Misc.

200

When you write with a pencil, which type of muscle moves your finger?

skeletal

300

True or False. Bones are dead structures.

False

400

Describe how the muscles and bones work together to facilitate movement in our body. 

Paired muscles work by one contract while the other relaxes to move in one direction, then the other muscle contracts while the other relaxes to move in the other direction. 

500

Describe how the skeletal system works directly with another body system to maintain homeostasis in the body. 

Skeletal and muscle = facilitate movement 

Skeletal and circulatory= skeletal makes blood cells, circulatory circulates blood
