Questions
1. 1.ID: 793023914
Which structure is part of the central nervous system (CNS)?
A. Brain Correct
B. Somatic nervous system
C. Peripheral nerve pathways
D. Cranial nerves
The brain is part of the CNS. The peripheral nervous system (PNS)
consists of the cranial nerves and the spinal nerves. The PNS can be
divided into the somatic nervous system and the autonomic nervous
system.
Awarded 0.0 points out of 1.0 possible points.
2. 2.ID: 793023937
Which of the following is an insulating substance for the neuron?
A. Schwann sheath
B. Myelin Correct
C. Neurilemma
D. Node of Ranvier
Myelin is an insulating substance. The neurilemma is the same as a
Schwann sheath; it is the delicate tissue that surrounds each axon. The
nodes of Ranvier are interruptions at regular intervals that occur in the
myelin.

3. 3.ID: 793023902
Which neurons transmit impulses from neuron to neuron?
A. Unipolar neurons
B. Sensory neurons
C. Motor neurons
D. Interneurons Correct
Interneurons, or associational neurons, transmit impulses from neuron to
neuron. Motor neurons transmit impulses away from the CNS. Sensory
neurons carry impulses from the peripheral sensory receptors to the CNS.
Unipolar neurons have one process that branches shortly after leaving the
cell body.
Awarded 0.0 points out of 1.0 possible points.
4. 4.ID: 793023904
Which term describes successive, rapid impulses received from a single
neuron on the same synapse?
A. Temporal summation Correct
B. Spatial summation
C. Actuation
D. Facilitation
Temporal summation refers to the effects of successive, rapid impulses
received from a single neuron on the same synapse. Spatial summation
refers to the combined effect of
impulses from a number of neurons on a single synapse at the same time.
Facilitation refers to the effects of excitatory postsynaptic potential (EPSP)
on the plasma membrane potential.
Awarded 0.0 points out of 1.0 possible points.

Which of the following is an arterial bleed from the blood vessels that
lie within the grooves of the skull?
A. Subdural
B. Epidural Correct
C. Subarachnoid
D. Lumbar cisterna
An epidural hematoma develops from an arterial bleed of blood vessels
that lie within the grooves in the skull.
Awarded 0.0 points out of 1.0 possible points

6. 6.ID: 793023920
Which part of the brain contains all cell bodies and dendrites of the
neurons?
A. Gyri
B. Sulci
C. White matter
D. Gray matter Correct
The gray matter contains the cell bodies and dendrites of the neurons. The
gyri are the convolutions of the cerebrum. The sulci are the grooves
between adjacent gyri. The white matter contains myelinated nerve fibers.
Awarded 0.0 points out of 1.0 possible points.
7. 7.ID: 793023912
Which statement is true regarding Broca’s area?
A. Is responsible for receptive speech.
B. Is responsible for motor speech. Correct
C. Results in the inability to hear.

D. Is located in the right cerebral hemisphere.
Broca’s area is found on the left and is responsible for motor speech.
Deficits in this area result in the inability to form words, which is also
called expressive aphasia.
Awarded 0.0 points out of 1.0 possible points.
8. 8.ID: 793023924
Which statement is true regarding the cerebellum?
A. Makes up fibers of the corticospinal tract.
B. Maintains balance or posture. Correct
C. Controls respiration.
D. Is the location of cranial nerves V through VIII.
The cerebellum is responsible for balance and posture and is also
responsible for both conscious and unconscious muscle synergy. The
pons controls respirations and is the location of cranial nerves V through
VIII. The fibers of the corticospinal tract are made up in the basis
pedunculi.
Awarded 0.0 points out of 1.0 possible points.
9. 9.ID: 793023908
Which of the following is involved in pain transmission?
A. Posterior horn
B. Substantia gelatinosa Correct
C. Anterior horn
D. Dorsal root ganglia
The substantia gelatinosa is a structure involved in pain transmission. The
posterior horn (dorsal horn) is primarily composed of interneurons and
axons from sensory neurons. The anterior or ventral horn contains nerve
cell bodies for efferent pathways leaving the spinal cord. The dorsal root
