Answers | 100% Correct Answers |
Grade A+
Which is an anterior muscle?
A. Gluteus maximus
B. Quadriceps femoris
C. Biceps femoris
D. Adductor magnus
Ans: B. An anterior muscle is located near the front of the body. Of those listed, the
quadriceps( frontal thigh muscle) is the most anterior.
How might the headrest on a car prevent traumatic injury?
A. By limiting hyperflexion of the neck
B. By limiting hyperextension of the neck
C. By reducing vertebral compression
D. By preventing disc degeneration
Ans: B. The headrest prevents the head from moving too far backward, or hyperextending
the neck beyond its normal range.
,Which might you expect to see in a whiplash injury?
A. Cardiopulmonary problems
B. Side-to-side spinal curvature
C. Eventual herniation of discs
D. Traumatic injury to ligaments
Ans: D. Because of the hyperflexion and hyperextension caused by such a collision, it is not
uncommon to find tears or stretching of the ligaments of the spine. The injury is front-to-
back, making choice B unlikely, and a herniated disc (choice C) is more of a compression
injury.
Muscle contractions that normally move food along the human digestive system are known as
________.
A. defecation
B. osmosis
C. peristalsis
D. circulation
Ans: C. Defecation(choice A) is the elimination of waste. Osmosis (choice B) is the
movement of molecules across a membrane. Circulation (choice D) is the movement of blood
through the body. Peristalsis (choice C) is the involuntary, wavelike movement of muscles in
the intestine and elsewhere that pushes food along.
,Which type of nutrient does not provide the body with energy?
A. Vitamin
B. Carbohydrate
C. Fat
D. Protein
Ans: A. Some nutrients supply energy, and others support metabolism. Nutrients in the first
set include carbohydrates, proteins, and fats. Those in the secound set include vitamins,
minerals, and water.
Where would you be likely to find a Schwann cell?
A. In the digestive system
B. In the nervous system
C. In the skeletal system
D. In the muscular system
Ans: B. Schwann cells wrap around the nerve fibers and form the myelin sheath in the
peripheral nervous system.
How does the nervous system work with the muscular system?
A. The muscles of the body produce chemicals that feed the nerves.
, B. The nervous system tells the muscles how to respond to the environment.
C. The nervous system releases chemicals that remove excess waste from the muscles.
D. The muscular system provides input that allows the nerves to make decisions.
Ans: B. The nervous system is made up of the brain, spinal cord, and nerves. It receives and
transmits signals from the environment that regulate voluntary and involuntary movement.
Which part of the nervous system includes the femoral , radial, and ulnar nerves?
A. Somatic
B. Autonomic
C. Sympathetic
D. Parasympathetic
Ans: A. The symphathetic and parasympathetic systems (choice C and D) are part of the
autonomic nervous system (choice B), which controls involuntary actions of the smooth
muscles, glands, and heart. The somatic nervous system (choice A) has to do with reception
of external stimuli and voluntary control of the muscles.
Where might a herniated lumbar disc be most likely to create pain?
A. Along the radial nerve
B. Within the spinal cord
C. Along the sciatic nerve
