Completion
Fill in the line to complete each statement.
11. Nerves and blood vessels in the skin are located in the ____dermis_________________.
12. _____skeletal___________________ muscle is sometimes called striated muscle.
13. Smiling is an action controlled by ___voluntary_____________________ muscles, because it is an action
that a person can control.
14. The lower layer of the skin is called the ___dermis_____________________.
15. A(n) ___ligaments_____________________ is the strong connective tissue that holds the bones together
in movable joints.
16. Backward or forward type of motion is possible with a _____hinge______________ joint.
True or False
If the statement is true, write true. If it is false, change the underlined word or words to make the statement
true.
___true________ 17. Smooth muscles are involuntary muscles.
__contract__ 18. Muscle cells can only extend.
____less____ 19. An adult skeleton has more cartilage than a child’s skeleton.
____true___ 20. The backbone is made up of 26 small bones, or vertebrae.
____true___ 21. Exercise is important for muscles because it helps maintain strength and flexibility.
_ cartilage_ 22. Much of a newborn’s skeleton is made of bone.
_melanin__ 23. Halogen, a pigment in the skin, helps protect the skin from sunburn.
__sweat
24. Shivering helps to cool your body.
__true__ _ 25. The outermost layer of the skin is the epidermis.

26. Label the type of joint represented by each of the figures shown above.

27. Bones soaked in vinegar demonstrates the importance of:
having enough calcium in your diet
`
28. Your skeletal system is meant, in part, to protect. Explain using as many examples as you can think
of.
Skull - brain
ribs - lungs
vertebrae – spinal cord
29. How does the skin help the body maintain a constant body temperature?
When you get too warm, you sweat and the sweat evaporates cooling you off
30. Are bones alive? Explain.
Yes, they undergo growth and development. Bones make certain
blood cells and release certain minerals into the blood when needed.
31. Explain how skeletal muscles work in pairs?
They can contract but not extend. Each skeletal
muscle can only pull a bone in one direction. There’s another muscle attached to the bone that can pull
the bone in the opposite direction.
32. If smooth muscle had to be controlled consciously, what problems could you foresee in day-to-day living?
You’d have to think about breathing and digesting your food, etc. You couldn’t sleep or you
would die and you’d have too many things to think about at once.
33. How does skin protect your body?
It helps keep out infections and regulate temperature, it
also prevents the loss of fluids from the body.
Use the graph to answer questions 34-36.
The graph shows the effects of the temperature of the environment on
A boy’s skin temperature and on the temperature inside his body
34. As the temperature of the environment rises, what
happens to the boy’s internal body temperature?
The boy’s internal temperature stays constant as
the environmental temperature rises.
How does this demonstrate homeostasis?
This demonstrates the stability of his internal
temperature despite changes in the external temp.
35. What happens to the temperature of the boy’s skin?
His skin temperature rises as the external
temperature increases.
Why is this pattern different from the pattern shown by the boy’s internal body temperature?
His skin is in direct contact with the external environment (the air) so it warms as the
external temp. increases. Several processes combine to keep the internal body temp.
constant.
36. Suppose the boy went outdoors on a chilly fall morning. Predict what would happen to his
internal body temperature and his skin temperature. Explain.
His internal temperature would remain constant due to homeostasis, while his skin
temperature would decrease.
