Autonomic Nervous System

Question 1

autonomic NS

Answer 1

smooth + cardiac muscle, glands, sensory info from organs

Question 2

somatic efferent pathway

Answer 2

one neuron system

Question 3

somatic neurotransmitter and response

Answer 3

acetylcholine, excitatory

Question 4

autonomic efferent pathway

Answer 4

two neuron system (pre + postsynaptic)

Question 5

autonomic neurotransmitter and response (presynaptic)

Answer 5

acetylcholine, excitatory

Question 6

autonomic neurotransmitter and response (postsynaptic)

Answer 6

varies between sympathetic and parasympathetic, excitatory or inhibitory

Question 7

sympathetic innervation origin

Answer 7

thoracolumbar

Question 8

parasympathetic innervation origin

Answer 8

CN 3, 7, 9, 10 and sacral

Question 9

sympathetic fiber length

Answer 9

presynaptic-short, postsynaptic-long

Question 10

parasympathetic fiber length

Answer 10

presynaptic-long, postsynaptic-short

Question 11

sympathetic location of ganglia

Answer 11

close to spinal cord

Question 12

parasympathetic location of ganglia

Answer 12

near effector organs

Question 13

parasympathetic nervous system function

Answer 13

inhibits or slows down body functions, except for digestion

Question 14

parasympathetic nervous system cranial outflow

Answer 14

oculomotor, facial, glossopharyngeal, vagus

Question 15

parasympathetic NS sacral outflow

Answer 15

exits ventral rami as pelvic splanchnic n

Question 16

sympathetic nervous system function

Answer 16

speeds up or stimulates body function, except digestion

Question 17

sympathetic NS location

Answer 17

thoracolumbar region - lateral horn

Question 18

sympathetic NS outflow

Answer 18

1. synapse at paravertebral ganglia at the same level
2. synapse at paravertebral ganglia at different level
3. does not synapse on chain (splanchnic n) and synapse at prevertebral ganglia
