Group of answer choices

upper motor neuron

postganglionic neuron

preganglionic neuron

autonomic ganglion

somatic neuron

preganglionic neuron

The sympathetic nervous system of the ANS is also known as the

Group of answer choices

thoracolumbar division

craniosacral division

autonomic division

ganglionic division

somatic division

thoracolumbar division

All of the following are autonomic ganglia EXCEPT: 

Group of answer choices

dorsal root ganglia

prevertebral ganglia

ciliary ganglia

terminal ganglia

sympathetic trunk ganglia

dorsal root ganglia

Sympathetic fibers:

 

have short post-ganglionic

 

originate in the brain

 

originate in the spinal cord

 

are unmyelinated fibers

 

have long pre-ganglionic

originate in the spinal cord

In the autonomic nervous system, the number of neurons between the CNS and the visceral effector is:

 

4

 

5

 

3

 

1

 

2

2

The pre-ganglionic fibers of the autonomic nervous system (sympathetic and parasympathetic) release

 

epinephrine

 

glycine

 

GABA

 

acetylcholine

 

norepinephrine

acetylcholine

The sympathetic division of the ANS causes a / an

 

none of the above

 

decrease in the heart activity

 

increase in the heart activity

 

constriction of the pupils

 

increase in the digestive processes and motility

increase in the heart activity

All of the following are fight or flight responses EXCEPT

 

increase in the digestive secretions

 

dilation of the pupils

 

increase in heart rate

 

dilation of the bronchioles

 

increase in blood pressure

increase in the digestive secretions

The ganglia that lie along the either side of the anterior vertebral column are the:

 

superior mesentric ganglia

 

pervertebral ganglia

 

terminal ganglia

 

dorsal root ganglia
