1

signal enters cord as what type of input?

afferent sensory input

2

afferent sensory input synpases in what location?

dorsal horn at tract of lissauer

3

what sorts between pain and temperature information?

tract of lissauer

4

after synpasing in the dorsal horn at tract of lissauer, where is the next synpase location?

from gray matter to white matter to become the lateral spinothalamic tract

5

lateral spinothalamic tract ascends into what region?

brain

6

lateral spinothalamic tract carries what type of information?

cutaneous message

7

lateral spinothalamic tract terminates at the

ventral posterolateral nucleus of thalamus

8

thalamus synapses to...

brodmann area 3, 1, 2 and insular cortex

9

brodmann area 3, 1, 2 is known as...

primary somatosensory cortex

10

insular cortex is also known as...

insula or isle of reil

11

anterior portion of insular cortex regulates what type of function?

visceroautonomic function

12

insula will forward message to what region of the brain?

hypothalamus (adenohypophysis/anterior hypothalamic nucleus)

13

hypothalamus regulates what function?

regulation of autonomic function

14

anterior hypothalamic nucleus becomes what tract?

descending autonomic tract

15

the descending autonomic tract passes through which structure?

brainstem

16

descending autonomic tract travels to...

original site of dermatomal thermoregulation

17

preganglionic sympathetic fibers synapse with...

sympathetic paravertebral ganglionic chain

18

what are the three synpase outcomes of preganglionic sympathetic fibers?

ascend to ganglion at a higher cord level, descend to ganglion at a lower cord level and stay at same ganglionic level

19

what is the most likely outcome for dermatomal thermoregulation?

staying at same ganglion level

20

preganglionic sympathetic fibers will neurotransmit...

AcH

21

AcH stimulates...

nicotinic postganglionic fiber

22

nicotinic postganglionic fiber transmits...

epinephrine

23

nicotinic postganglionic fibers transmit epinephrine which will terminate where and cause what effect?

tunica media and constrict vasculature

24

what cord levels make up the sympathetic nervous system?

T1-L3

25

sympathetic chain extends in what direction?

upward, which is a reflection of "core activity below" (supports pattern analysis)

26

are warmth receptors myelinated or unmyelinated?

unmyelinated

27

are cold receptors myelinated or unmyelinated?

myelinated - saltatory

28

ambient control is...

dermatome specific
