HESI A2 A&P Exam Questions With Complete
Solutions
Which is an anterior muscle?
A. Gluteus maximus
B. Quadriceps femoris
C. Biceps femoris
D. Adductor magnus
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
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
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
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

A. Vitamin
B. Carbohydrate
C. Fat
D. Protein
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
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.
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
A. The symphathetic and parasympathetic systems
(choice C and D) are part of the autonomic nervous
system (choice B), which controls involuntary
