MULTIPLE CHOICE

 

1. The autonomic nervous system coordinates which of the following?

a.	High-level cognitive function
b.	Balance and affect
c.	Internal organs of the body
d.	Balance and equilibrium

 

 

ANS:  C

The autonomic nervous system coordinates the internal environment of the body by the sympathetic and parasympathetic nervous systems. The other options are associated with the cerebral cortex; its function consists of determining intelligence, personality, and motor function.

2. The major function of the sympathetic nervous system is to:

a.	orchestrate the stress response.
b.	coordinate fine motor movement.
c.	determine proprioception.
d.	perceive stereognosis.

 

 

ANS:  A

Stimulation of the sympathetic branch of the autonomic nervous system prepares the body for emergencies for fight or flight (stress response). The cerebellum plays a key role in the coordination of fine motor movements. Recognition of body parts and awareness of body position (proprioception) are dependent on the parietal lobe. Stereognosis is the ability to perceive the weight and form of solid objects by touch and is not under sympathetic control.

3. The parasympathetic nervous system maintains the day-to-day function of:

a.	digestion.
b.	response to stress.
c.	lymphatic supply to the brain.
d.	lymphatic drainage of the brain.

 

 

ANS:  A

The parasympathetic division functions in a complementary and counterbalancing manner to conserve body resources and maintain day to day body functions, such as digestion and elimination.

4. Cerebrospinal fluid serves as a:

a.	nerve impulse transmitter.
b.	red blood cell conveyer.
c.	shock absorber.
d.	mediator of voluntary skeletal movement.

 

 

ANS:  C

Cerebrospinal fluid circulates between an interconnecting system of ventricles in the brain and around the brain and spinal cord, serving as a shock absorber.

5. Diabetic peripheral neuropathy will likely produce:

a.	hyperactive ankle reflexes.
b.	diminished pain sensation.
c.	exaggerated vibratory sense.
d.	hypersensitive temperature perception.

 

 

ANS:  B

Peripheral neuropathy is a disorder of the peripheral nervous system that results in motor and sensory loss in the distribution of one or more nerves, usually in the hands and feet. Patients may have sensations of numbness, tingling, burning, and cramping. In moderate to severe diabetic neuropathy, there is wasting of the foot muscles, absent ankle and knee reflexes, decreased or no vibratory sensation below the knees, and/or loss of pain or sharp touch sensation to the midcalf level.
