MULTIPLE CHOICE

 

1. The 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:  B

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 (CNs), the 31 pairs of spinal nerves, and all of their branches.

2. 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 very easily and becomes angry. The nurse recalls that the cerebral lobe responsible for these behaviors is the __________ lobe.

a.	Frontal
b.	Parietal
c.	Occipital
d.	Temporal

 

 

ANS:  A

The frontal lobe has areas responsible for personality, behavior, emotions, and intellectual function. The parietal lobe has areas responsible for sensation; the occipital lobe is responsible for visual reception; and the temporal lobe is responsible for hearing, taste, and smell.

3. Which statement concerning the 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:  B

The hypothalamus is a vital area with many important functions: body 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 in the thalamus.

4. 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:  C

The spinal cord is the main highway for ascending and descending fiber tracts that connect the brain to the spinal nerves; it is responsible for mediating reflexes.

5. 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?

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:  C

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 the sensations 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.
