Topics Covered

This Section Test deals with the muscular skeletal system. The structure of bones, how joints function, and the various ways in which muscles drive the body's motor abilities are all covered. How the nervous system interacts with this system to produce voluntary movement and reflexes are also covered.

Section Test

1. Which of the following types of muscle tissues is found in the walls of the stomach, intestines, and blood vessels?

cardiac muscle
smooth muscle
skeletal muscle
voluntary muscle

2. Which of the following types of muscle tissues is responsible for moving most parts of the body?

cardiac muscle
smooth muscle
skeletal muscle
involuntary muscle

3. The contraction of a muscle is terminated by the action of

calcium ions
axon terminals
acetylcholine
acetylcholinesterase

4. The sliding filament theory is used to explain the

production of melanin pigment
ossification of bone
growth of hair cells
contraction of muscle

5. Muscles cells that contract without nervous stimulation are found in

skeletal and smooth muscles
smooth and cardiac muscles
skeletal and cardiac muscles
skeletal muscles only

6. The muscles of the digestion system consists of

cardiac muscle
smooth muscle
skeletal muscle
connective tissue

7. Muscles that cause a joint to bend are called

flexors
origins
extensors
insertions

8. A sarcomere

is the functional unit of muscle contraction
uses ATP
consists of myofibrils
all of the above

9. Muscles move bones by

puling them
pushing them
stretching back and forth
relaxing

10. Which of the following occurs when skeleton muscles contracts?

the myosin heads remain attached to actin filaments
the myosin filaments overlap
the myosin heads bend outward
the sarcomeres shorten

Your score is 0 / 0
