Q

what kinda of receptors are found in the sympathetic system

Study These Flashcards
A

adrenergic receptors

25
what do adrenergic receptors respond to
NE and E
26
which adrenergic receptors are more excited to NE than E
alpha 1 and 2
27
Location of alpha 1 adrenergic receptors
most receptors - salary glands - repro organs - urinary bladder
28
what adrenergic receptors used Ca 2nd messengers to excite receptors and G proteins
alpha 1
29
what does Alpha 2 adrenergic receptors use to cause inhibitory effects
- G proteins | - cAMP
30
location of alpha 2 receptors
- G1 tract (relaxes muscles) | - pancreatic secretions (decreased activity)
31
which adrenergic receptors love NE and E equally
Beta 1
32
function of beta 1 using g- proteins and cAMP
excitatory to increase heart rate or control kidneys to control BP
33
what causes kidneys to secrete renin
beta 1 adrenergic receptors
34
what adrenergic receptors love E more than NE
beta 2
35
what adrenergic receptors uses cAMP to inhibit
beta 2
36
function of beta 2
- inhibit respiratory airways controlled by B1 | - blood vessels
37
which is the newest adrenergic receptors
beta 3
38
function of beta 3
uses cAMP to excite, causes adipose tissues to break down
39
what does beta 3 love more
ME
40
how is NMJ formed
motor neuron meeting skeletal muscle cells
41
does the somatic ns have ganglions
no
42
what events take place at NMJ
ap in motor neurones arrives at axon terminal --> Ca2+ influx --> releases ACh --> binds with chemical receptors on motor end plate --> brings about an end plate potential --> full blown ap
43
what is motor end plate
area on skeletal muscle that has receptors
44
what is gp (similar to EPSP) that occurs at skeletal muscles
end plate potential (EPP)
45
what digested ACh after potential
ACh estrase
46
what does ACh get broken down to
acetic acid (waste) and choline (recycled)
47
what causes death with spider venom
too much ACh which keeps depolarizing which cuases respiratory system to seize
48
what causes decreased ACh release and causes flacid paralysis and then death
botulism toxins
49
no muscle contraction aka
placid paralysis
50
curare symptoms
- blocks ACh receptors at motor EPP which causes paralysis
51
when was curare used
during war times
52
organophosphates is found in
pesticides
53
what prevents breakdown of ACh cuz there's reduces AChE
organophosphates
54
what is great muscle weakness, is a autoimmune disease and ACh slowly destroyed
myasthenia gravis
55
when can't eyelids contract, diffculty walking, cuz muscles fall apart
myasthenia gravis
56
Polio cause
poliovirus (contain mined water and food)
57
what happens when one has polio
attacks motor neurons --> paralysis
58
what disease attacks neurofilaments
ALS aka lou-gehrigs
59
what happens to body stuff happens in ALS
- motor neuron disease - high glutamate levels (slow paralysis) - mitochondria dysfunction
