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
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 (choice C), and humerus (choice D) are arm bones.
The ovaries are part of the ___________.
A. skeletal system
B. nervous system
C. lymphatic system
D. reproductive system - correct answer -D.
The ovaries are the egg-producing reproductive organs.
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.
, 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.
Which parts of the heart are separated by the mitral valve?
A. Left atrium and right atrium
B. Right atrium and right extremities
C. Left ventricle and right ventricle
D. Left atrium and left ventricle - correct answer -D.
The mitral valve opens to allow oxygenated blood collected in the left atrium to flow into the left
ventricle
How might vitamin D deficiency present?
A. As bleeding gums
B. As swollen extremities
C. As red patches
D. As crooked bones - correct answer -D.
The disease known as rickets is a product of vitamin D deficiency and results in the softening and
bending of bones.
How does the lymphatic system work with the circulatory system?
A. The circulatory system produces red blood cells for the lymphatic system.
B. Lymph draws excess fluid from the cells and deposits it into the blood vessels.
C. The heart regulates the production of lymph in the lymph glands.
D. White cells from the lymphatic system eliminate excess red blood cells. - correct answer -B.
One of the jobs of the lymphatic system is to prevent excess fluid from accumulating in tissues by
collecting it and moving it into the circulatory system via the brachiocephalic veins.
