Where would you find the cholinergic recpetor nicotinic ? |
Neuromuscular junctions and adrenal medullary cells |
|
|
Where would you find the cholinergic recptor muscarinic? |
Effectors of the parasympathetic system (smooth muscle, cardiac muscle and glands) most sweat glands and skeleta muscle, blood vessels |
|
|
Name the four different andrenergic receptors ? |
a1 - alpha 1 a2 - alpha 2 B1 - Beta 1 B2 - Beta 2 |
|
|
Name the main location for alpha 1 receptors ? |
Smooth muscle in blood vessels, smooth muscle in iris |
|
|
Name the main location for alpha 2 receptors ? |
Platelets, smooth muscle in some blood vessels, sweat glands |
|
|
Name the main location for Beta 1 receptors ? |
Cardiac muscle, liver, uterus |
|

What is the main effect of stimulation of alpha 1 receptors ? |
Vasoconstriction of peripheral blood vessels and pupil dilation |
|
|
What is the main effect of stimulation of alpha 2 receptors ? |
Platelet aggregation, dilation of smooth muscle and increased sweating |
|
|
What is the main effect of stimulation of Beta 1 receptors ? |
Increased heart rate and increased contarctility of the heart |
|
|
What is the main effect of stimulation of the Beta 2 receptors ? |
Bronchodilation and glycogenolysis ( relation of uterus) |
|
|
Name the neurotransmitters that are involved with adrenergic receptors ? |
Adrenaline and noradrenaline |
|
|
What neurotransmitter is the target of anticholinergic drigs ? |
Acetylcholine |
|
|
Describe the effects of betablocker? |
Effects HR (decreases), decreases myocardial contractility, decreases BP bronchodilation |
|
|
Name the main location of receptors (Betablocker) ? |
Heart and lungs |
|
|
What effects would you expect to see if you administered an adrenoreceptor agonist ? |
↑ HR ,↑ BP, bronchodilation , pupillary dilation, ↓ GI motility, ↑ secretion of Adrenalin |
|
|
Give an example of an adrenorecpetor agonist medication ? |
Adrenalin , salbutamol |
|
|
Would anticholinergic drugs be considered agonist or antagonist ? Why ? Give an example |
Antagonist - they block receptors for ACh thus inhibiting the effect of ACh |
