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.
Awarded 0.0 points out of 1.0 possible points.
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.

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.
5. 5.ID: 793023922
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.

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.

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.
