Question 1

what does the ANS system include

Answer 1

• the sympathetic division
• the parasympathetic division

Question 2

what does the ANS system do

Answer 2

• involved in maintaining many homeostatic set points
• ex. BP, body temperature, respiratory airflow

Question 3

what are the purpose of feedback techniques

Answer 3

• to calm the body down
• ex. purge, don’t move, drop resting heart rate

Question 4

what are the effectors in the brain

Answer 4

glands, and smooth or cardiac muscles

Question 5

what are baroreceptors

Answer 5

• they deal with pressure
• send stimulus to brain saying there’s too much or not enough blood flow it then alters the heart

Question 6

sympathetic division

Answer 6

• fight or flight
• prepares body for physical activity
  increases heart rate, BP, airflow, ect..

Question 7

parasympathetic division

Answer 7

• rest and digest
• calms body functions and helps bodily maintenance

Question 8

somatic pathway

Answer 8

one axon

Question 9

autonomic pathway

Answer 9

two axons

Question 10

what are the 2 types of autonomic pathways

Answer 10

sympathetic and parasympathetic

Question 11

are parasympathetic and sympathetic pathways opposites

Answer 11

no they are teammates because the work together in order to maintain set points

Question 12

what takes 2 synapses

Answer 12

a visceral involuntary response

Question 13

parasympathetic synapses

Answer 13

1. ACh and nicotinic
2. ACh and muscerinic

Question 14

sympathetic synapses

Answer 14

1. ACh and nicotinic
2. ACh or adrendric

Question 15

muscerenic receptors

Answer 15

• can be alpha or beta
• only bind to NE

Question 16

alpha is

Answer 16

excitatory

Question 18

adrenal glands belong to

Answer 18

sympathetic

Question 19

beta is

Answer 19

inhibitory

Question 20

what is dual intervention

Answer 20

• when 2 nerves go to one source
• typically one is sympathetic and one is parasympathetic ex. pupils

Question 21

without dual intervention

Answer 21

• some blood vessels only have one nerve path
• rare

Question 22

Answer 22

• problems with their parasympathetic nerve responses

ex. digestion ; may have feeding tube

Question 23

Answer 23

• short pre and long post
• result : widespread and overlapping branches (ramus and plexus)

Question 24

parasympathetic anatomy

Answer 24

• long pre and short post
• result : specific and low chance of overlapping
