Q

autonomic nervous system

A
  • visceral motor (invaluntary)
  • conducts inpulses from the CNS to the cardiac muscles, smooth muscles and glands
  • maintains homeostasis: by including body temperature and ergulating the activity of internal organs and vasculature

Q

hypothalamus do

A
  • activates the adrenal cortical system by releasing CRF (corticotropin releasing factor) which activates ACTH to release 30 hormones into the blood
  • activates the sympathetic NS releases norepinephrine and epinepherine into blood stream and activate glands and muscles

A

salivary

18
Q

what does CN 9 go to

A

salivary

19
Q

what does CN 10 go to

A

heart, lungs, stomach, liver and kidney

20
Q

what does the pelvic splanchnic n go to

A

repro and bladder

21
Q

what ganglia does CN 10 go to

A

intramural ganglia

22
Q

what does pelvic nerves go to

A

intramural ganglia

23
Q

where are autonomic pressure receptors found

A

in the aortic baroreceptors, carotid sinuses, and lungs

24
Q

where are the autonomic stretch receptors respond to

A
  • distention of the veins, bladder or intestines
25
Q

what are chemoreceptors sensitive to

A

chemical concentrations in the blood that are located in the carotid and aortic bodies (respond to O2) and medulla that respond to Hydrogen and CO2

26
Q

what does the baroreceptors send information about

A
  • stretch in the arch of the aorta and carotid sinus
  • gets sent to the medulla via the CN 9 and 10
  • parasympathetic trunk
27
Q

efferent to spinal cord - sympathetic trunk

A

accelerates HR

28
Q

efferent parasympathetic direct to the SA node

A

slows HR

29
Q

neurotransmitters in the sympathetic nervous system

A
  • uses ACH and norepinephrine in CNS
  • ACH and Nicotinic receptor in ganglion
  • Norepinephrine at target tissue
30
Q

neurotransmitter in the parasympathetic NS

A
  • ACH in CNS
  • ACH and nicotinic receptor in ganglion
  • ACH at target cell
31
Q

Anticholinergic

A

lowering ACH

32
Q

Cholinergic

A

increase ACH

33
Q

Diaphragmatic breathing

A

reduces cortisol and increase attention

34
Q

Spinal core injury above T6

A

Autonomic dysreflexia

35
Q

PD

A

dysaytonimia, GI system issure, temperature dysregulation, pupillary issues, blood pressure drops

36
Q

POTS

A
  • cardiac instability, fainting, postural hypotension and weakness
