Flashcards in Block 2 Autonomic Nervous System Deck (41):
1

ANS is solely blank

efferent

2

two ANS subdivisions

sympathetic, parasympathetic

3

emybronic origin of sympathetic and parasympathetic

neural crest

4

preganglionic neuron is in the blank

cns

5

postganglionic neuron is in the blank

pns

6

preganglionic sympathetic fibers travel in the blank root of the spinal nerve before entering sympathetic trunk via blank

ventral, white rami communicans

7

postganglionic sympathetic fibers are contained within ever spinal nerve and goes to where

all hair follics, blood vessels, sweat glands

8

preganglionic parasympathetic fibers leave the spinal nerve as the blank

pelvic splanchnic nerves

9

site of information exchange within nervous system

synapse

10

cell body and fiber originate in the brain and spinal cord

preganglionic

11

cell body and fiber originates in PNS within a ganglion

postganglionic

12

collection of cell bodies in cns

nucleus

13

collection of cell bodies in pns

ganglion

14

preganglionic neuron is always in the blank of the cns

lateral horn

15

sympathetic preganglionic neuron originates at one of these levels of the spinal cord

T1-L2 or L3

16

postganglionic neuron is always in the pns and can be located in the blank or blank

sympathetic trunk, prevertebral ganglia

17

paired chains of ganglia connected by nerve fibers, location of sympathetic ganglia

sympathetic trunk

18

sympathetic trunk location

paravertebral

19

two sides of sympathetic trunk unite in the coccygeal region as the blank

ganglion impar

20

prevertebral ganglia are associated with unpaired blank

visceral arteries (celiac, superior mesenteric, inferior mesenteric)

21

input to the sympathetic trunk is via 14 pairs of the blank

white rami communicantes

22

output from the sympathetic trunk is via 31 pairs of blank

gray rami communicantes

23

preganglionic neurotransmitter is blank

ach

24

postganglionic nt is usually blank

norepinephrine

25

postganglionic fibers to sweat glands are an exception and use blank as an nt instead of blank

ach, norepinephrine

26

four major groups of ganglia that preganglionic fibers can terminate in without synapsing

greater, lesser, least, lumbar splanchnics

27

greater splanchnic nerve synapses in blank and supplies blank

celiac ganglia, foregut

28

lesser and least splanchnic nerves synapse in the blank and supplies blank

aorticorenal ganglia, kidney

29

superior mesenteric ganglion supplies blank

midgut

30

no splanchnic nerve goes directly into the blank

superior mesenteric ganglion

31

lumbar splanchnic nerve synapses in blank and supplies blank

inferior mesenteric ganglion, hindgut

32

prevertebral ganglia are located blank to vertebral column

anterior

33

postganglionic sympathetic fibers from prevertebral ganglia are distributed to blank

abdominal organs

34

thoracolumbar contains blank

sympathetics

35

craniosacral contains blank

parasympathetics

36

CN3 innervates sphincter pupillae for the light response via blank

short ciliary nerves

37

postganglionic parasympathetic fibers innervate these

some cranial nerves, submandibular/sublingual glands

38

cn9 parasympathetic fibers travel with the blank and synapse in the blank

lesser superficial petrosal nerve, otic ganglia

39

preganglionic fibers of vagus nerve go all the way to the gut and these ganglia are called blank

terminal ganglia

40

parasympathetic nt

ach

41

sacral portion of parasympathetic preganglionic fibers control blank

reproductive organs, sexual response, micturition, defecation
