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.
Question 2
,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.
Question 3
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.
Question 4
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.
Question 5
Which type of nutrient does not provide the body with energy?
A. Vitamin
B. Carbohydrate
C. Fat
D. Protein
Correct Answer
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.
,Question 6
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.
Question 7
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.
Question 8
Which part of the nervous system includes the femoral , radial, and ulnar nerves?
A. Somatic
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.
Question 9
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.
, Question 10
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 (choice C), and humerus (choice D) are arm bones.

Of the following processes, which one is a different level of defense from the others?
A. A low pH in the stomach
B. Cilia present in the trachea
C. Body cells recognizing a pathogen
D. Mucus present in the nasal cavity
Correct Answer
C. A low pH in the stomach (choice A), cilia in the trachea (choice B), and mucus (D) are primary
defenses. Cells recognizing a pathogen (choice C) is a third line of defense.
Question 13
Which organ system is primarily responsible for regulating muscle growth?
A. The skeletal system
B. The endocrine system
C. The nervous system
D. The reproductive system
Correct Answer
B. Hormones from the endocrine system, particularly from the pituitary gland, regulate growth.
Question 14
Which parts of the heart are separated by the mitral valve?
A. Left atrium and right atrium
