Name the 2 types of cholinergic receptors
Muscanaric Nicotonic
State the main locations for muscanaric receptors
sweat glands skeletal blood vessels
State the main location for nicotonic receptors
cells of adrenal medulla neuromuscular end plates of skeletal muscles
Name the neurotransmitter that is affiliated with cholinergic receptors
Acetylcholine
state the section of the ANS that would be affected by medications that either stimulate or inhibit these receptors
parasympathetic
Describe the effect of administering an agonist medication on muscanaric receptors
stimulates parasympathetic response
Describe the effect of administering an antagonist medication on muscanaric receptors
block paraysympathetic response
name the four adregenic receptors
a1, a2, b1, b2
state the main location for a1 receptors
vascular smooth muscle, pupils, heart
state the main location for a2 receptors
smooth muscle, presynaptic adregenic and choligernic nerve terminals
state the main location for b1 receptors
heart
state the main location for b2 receptors
liver, bronchiole smooth muscle, uterus
Name the two hormones that activate adrenergic receptors
noradrenaline, adrenaline
State the section of the ANS that would be affected by medications that either stimulate or inhibit these receptors
sympathetic nervous system
Describe the effect of administering an agonist medication on these receptors
mimic the effects of stimulation by the sympathetic nervous system
Give an example of an agonist medication in adrenergic receptors
salbutamol
state the specific effects adrenaline would have on a and b
• increased cardiac contractility • increased heart rate • increased blood pressure • bronchodilation
State the specific effects noradrenaline would have on a receptors
increase bp
describe the effect of administering an antagonist medication on adrenergic receptors
compete at receptor site to inhibit adrenergic sympathetic stimulation
