9. A patient presents with a loss of sensation to the skin over the shoulder. Injury to
which of the following nerve cells would most likely affect the conduction of sensory
information to the central nervous system?
(A) Multipolar neurons
(B) Bipolar neurons
(C) Unipolar or pseudounipolar neurons (D) Neurons in the ventral horn
(E) Neurons in sympathetic chain ganglia
Give this one a try later!
, 9. The answer is C. Sensation from the skin is carried by GSA fibers, and
their cells are uni- polar or pseudounipolar types located in the dorsal
root ganglia. Multipolar neurons and neurons in the ventral horn and in
sympathetic chain ganglia are motor neurons. Bipolar neurons are sensory
neurons, but they are not somatic sensory neurons.
4. A 16-year-old patient received a stab wound, and axons of the general somatic
efferent (GSE) neurons to the shoulder mus- cles were severed. The damaged axons:
(A) Would carry impulses toward the cell bodies
(B) Would carry impulses away from the cell bodies
(C) Would carry pain impulses
(D) Are several in numbers for multipolar
neurons
(E) Are found primarily in the gray matter
Give this one a try later!
4. The answer is B. The axons of the neurons carry impulses away from the
cell bodies, and dendrites carry impulses to the cell bodies. The axons
contain sensory or motor fibers. Multipolar neurons have several dendrites
and one axon. The GSE neurons do not carry sensory impulses. The gray
matter of the central nervous system consists largely of neuron cell bodies,
dendrites, and neuroglia, whereas the white matter consists largely of
axons and neuroglia
8. A 33-year-old male patient complains of feeling severe pain when he tries to turn
his neck. A physician realizes that the problem is in his pivot (trochoid) joint. Which of
the following joints would most likely be examined?
(A) Atlantooccipital joint
(B) Atlantoaxial joint
(C) Carpometacarpal joint
