Question 11

Are the sympathetic and parasypathetic nervous systems autonomic or somatic?

Answer 11

autonomic

Question 12

Which neurotransmitter is released by the somatic nervous system and the autonomic nervous system?

Answer 12

somatic: acetylcholine

autonomic: acetylcholine and norepinephrine

Question 13

Viscera definition

Answer 13

internal organs

Question 14

Differences between somatic and autonomic nervous systems

Answer 14

somatic: voluntary, movement functions, single neuron pathway

autonomic: involuntary, internal homeostasis function, two neuron pathway

Question 15

Which neurons release acetylcholine, norepinephrine, and epinephrine

Answer 15

acetylcholine: pre and postganglionic neurons
norepinephrine: almost all sympathetic postganglionic neurons
epinephrine: adrenal medulla

mass of cell bodies in the peripheral nervous system

Answer 18

pre: neuron before the ganglion

post: neuron after the ganglion

Question 19

How do autonomic neurons have contrasting effects on organs?

Answer 19

different receptors can produce different effects

Question 22

Preganglionic neurons

Answer 22

neurons coming from the central nervous system to the ganglia

Question 23

Postganglionic neurons

Answer 23

neurons coming from the ganglia to the effectors
