1
What is an adrenergic?
Refers to a drug stimulating a receptor for nor-epinephrine or epinephrine
2
What is an afferent signal?
Signal from peripheral to Brain and spinal cord.
Bottom-up signal
3
What is anti-adrenergic?
Drug blocking receptors for nor-epi and epi
4
What is anti-cholinergic?
Refers to drug blocking receptor for ACH
5
What is cholenergic?
Drugs that stimulate of a receptor for ACH
6
What is efferent?
Signals that come from brain/spinal cord to peripherals
top-down
7
What is norepinephrine?
Naturally occurring catecholamine neurotransmitter in the sympathetic terminal sites
8
What is parasympatholytic?
agents that inhibit or block effects in the parasympathetic nervous system
9
What is Parasympathomimetic?
Agents that cause stimulation of the parssympathetic nervous system
10
What is sympatholytic?
Agents that block or inhibit the effects of the sympathetic system
11
What is sympathomimetic?
Drugs that mimic the effects of the sympathetic system.
12
The sympathetic and parasympathetic system belong to what system?
The autonomic nervous system
13
What does parasympathetic system control?
-it control day to day bodily function.
CAUSES SLUD.
14
What is SLUD?
-salivation
-lacrimation
-urination
-defecation
15
What does stimulation of the sympathetic system do?
It is characterized as the flight or fight response.
16
What is the neuroeffector site?
The terminal nerve site for parasympathetic or sympathetic system.
-where ACH ends for muscarinic parasympathetic system
-epi and nor epi for sympathetic systems
17
What is another word for cholinergic?
Parasympathomimetic
18
What is another word for anti-cholinergic?
Parasympatholytic
19
What is another word for adrenergic?
Sympathomimetic
20
What is another word for anti-adrenergic?
Sympatholytic
21
Effects of Parasympathetic stimulation on heart
(SA node and contractility)
- SA NODE slowing of rate(decreased HR)
-decreased contractility (decreased atrial force)
22
Effects of Parasympathetic stimulation on lungs
(On muscle and on mucous glands)
-construction of smooth muscle
-increased mucous secretion
23
What is ACH?
Acetylcholine
The chemical used in nerve impulses at all pre ganglionic sites but only in post ganglionic sites of the parasympathetic system
24
Effects of Parasympathetic stimulation on blood vessels
Vasoconstriction,
-increased blood pressure due to loss of elasticity
25
Effects of sympathetic stimulation on heart
Increased heart rate, increased contractility
26
Effects of sympathetic stimulation on lungs
Bronchodilation
Beta 2 effect
27
Effects of sympathetic stimulation on blood vessels
Vasodilation
28
What is an M1 innervation do?
Increased secretion in nasal passages
29
What is an M3 innervation do?
Bronchoconstriction of the airways
