ANSWERS
Which is an anterior muscle?
A. Gluteus maximus
B. Quadriceps femoris
C. Biceps femoris
D. Adductor magnus - correct answer- 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 - correct answer- 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 - correct answer- 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 - correct answer- 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

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 - correct answer- 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. - correct answer- 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
, 4 | Page
B. Autonomic
C. Sympathetic
D. Parasympathetic - correct answer- 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
D. Along the tibial nerve - correct answer- C. Damage to a disc
in the lower back will most likely cause pain radiating downward
along the sciatic nerve.
What is the name of the bone in the human thigh?
A. Ulna
B. Femur
C. Radius
D. Humerus - correct answer- B. The ulna (choice A), radius
