5

what is the main input of the ANS

from autonomic (visceral) sensory neurons

6

10

where does the autonomic nervous system get their input and output from?

get and give to cardiac and smooth muscle in two forms: sympathetic and parasympathetic

11

sympathetic and parasympathetic are sensory or motor

motor

12

two neuron chain

15

more neuron, more synapse =

more control

16

why does the autonomic nervous system have a two neuron chain

body has more control with more neurons and it has to have more control over the autonomic system bc you're not thinking about it

26

what nervous system prepares the body for emergencies

sympathetic division

27

another name for parasympathetic division is

craniosacral division

28

why is the parasympathetic division also called the craniosacral division

function cervical portion

comes out of brain, goes down thoracic, and synapses in SCG and get back to head

44

in sympathetic, do all synapse in a ganglia?

no

45

in sympathetic, the ones that go up to the head and heart, do they go into ganglia? where do they synapse?

they don't into ganglia, they synapse in the chain

46

in sympathetic, the lower portion that goes to your abdomen, does it go through ganglia? where does it synapse

it goes through ganglia, it goes through the chain but it doesn't synapse there. it synapses in ganglia

47

everything from the lungs up synapses where

in the sympathetic chain of ganglia

48

what is one difference between the sympathetic and parasympathetic autonomic system?

sympathetic: has sympathetic chain ganglia

parasympathetic: no chain

49

what response deals with flight or flight

sympathetic

50

where does the cervical portion of the sympathetic synapse

in the sympathetic chain of ganglia

51

what does the sympathetic nervous system do to your body to get it ready for it's response

flight or fight response:
increase heart rate
decrease digestion

52

glycogenolysis

when we need more glucose in the blood bc we used it, we have to pull it out

53

where do we get the glycogen to restore glucose levels after fight or flight respons

the live by glycogenolysis

54

lipolysis

getting glucose out of adipose tissue to restore after fight or flight, but it's not as easy as glycogenolysis

55

what is the enzyme that performs glycogenolysis and lipolysis and where is it made?

glycogon made in pancreas

56

you have just done a sympathetic response and have burned up all the glucose in your blood. you're out of the window of homeostasis. you have to fix it. what system is gonna fix it?

parasympathetic system bc it is going to release enzymes to break down glycogen that is stored in certain places in body

57

when you run out of glycogen in the liver and skeletal muscle, then where do you get glycogen

adipose tissue through lipolysis

58

how do you achieve lipolysis

get the sympathetic system WORKING

59

autonomic nervous comes out of what horn in the spinal cord

lateral horn

60

rami communicantes

leads to sympathetic chain of ganglia

61

if the ganglia is in the body, it is called

ganglia

62

if the ganglia runs alongside vertebral column and connected, it is called a

chain of ganglia

67

adrenal medulla pathway

sympathoadrenal
