Chapter 24 JARVIS neuro (QUESTIONS--
exam 3) questions with actual answers.
Two parts of the *nervous system* are the: a.
Motor and sensory.
b.
Central and peripheral.
c.
Peripheral and autonomic.
d.
Hypothalamus and cerebral. ANS -ANS: central and peripheral.
The nervous system can be divided into two parts—central and peripheral. The central nervous system
includes the brain and spinal cord. The peripheral nervous system includes the 12 pairs of cranial nerves,
the 31 pairs of spinal nerves, and all their branches.
The wife of a 65-year-old man tells the nurse that she is concerned because she has noticed a *change in
her husband's personality and ability to understand. He also cries and becomes angry very easily*. The
nurse recalls that the cerebral lobe responsible for these behaviors is the _____ lobe.
a.
Frontal
b.
Parietal
c.
Occipital
d.
Temporal ANS -ANS: frontal
,The frontal lobe has areas concerned with personality, behavior, emotions, and intellectual function.
The parietal lobe has areas concerned with sensation; the occipital lobe is responsible for visual
reception; and the temporal lobe is concerned with hearing, taste and smell.
Which of these statements *concerning areas of the brain* is true?
a.
The cerebellum is the center for speech and emotions.
b.
The hypothalamus controls body temperature and regulates sleep.
c.
The basal ganglia are responsible for controlling voluntary movements.
d.
Motor pathways of the spinal cord and brainstem synapse in the thalamus. ANS -ANS: The
hypothalamus controls temperature and regulates sleep.
The hypothalamus is a vital area with many important functions: temperature controller, sleep center,
anterior and posterior pituitary gland regulator, and coordinator of autonomic nervous system activity
and emotional status. The cerebellum controls motor coordination, equilibrium, and balance. The basal
ganglia control autonomic movements of the body. The motor pathways of the spinal cord synapse in
various areas of the spinal cord, not the thalamus.
The area of the nervous system that is responsible for *mediating reflexes* is the:
a.
Medulla.
b.
Cerebellum.
c.
Spinal cord.
d.
Cerebral cortex. ANS -ANS: spinal cord.
, The spinal cord is the main highway for ascending and descending fiber tracts that connect the brain to
the spinal nerves, and it mediates reflexes.
While gathering equipment after an injection, *a nurse accidentally received a prick* from an
improperly capped needle. To interpret this sensation, which of these areas must be intact?
Not on powerpoint
a.
Corticospinal tract, medulla, and basal ganglia
b.
Pyramidal tract, hypothalamus, and sensory cortex
c.
Lateral spinothalamic tract, thalamus, and sensory cortex
d.
Anterior spinothalamic tract, basal ganglia, and sensory cortex ANS -ANS: Lateral spinothalamic tract,
thalamus, and sensory cortex
The spinothalamic tract contains sensory fibers that transmit the sensations of pain, temperature, and
crude or light touch. Fibers carrying pain and temperature sensations ascend the lateral spinothalamic
tract, whereas those of crude touch form the anterior spinothalamic tract. At the thalamus, the fibers
synapse with another sensory neuron, which carries the message to the sensory cortex for full
interpretation. The other options are not correct.
A patient with *lack of oxygen to his heart will have pain in his chest and possibly the shoulder, arms, or
jaw*. The nurse knows that the statement that best explains why this occurs is which of these?
a.
A problem exists with the sensory cortex and its ability to discriminate the location.
b.
The lack of oxygen in his heart has resulted in decreased amount of oxygen to the areas experiencing
the pain.
c.
