The alpha adrenergic receptors are located in the effector organs of sympathetic nervous system. They are the most common type of alpha adrenergic receptor. Alpha adrenergic receptors tend to be excitatory. They have a greater affinity for nonepinephrine than epinephrine.

If a cell has alpha adrenergic receptors is it sensitive to norepinephrine?
If a cell has α-adrenergic receptors, it is sensitive to
Does epinephrine affect the muscarinic receptors?
No. Muscarinic receptors are affected by acetylcholinergic neurotransmitters (ie. muscarine, atropine). Only the parasympathetic nervous system have muscarinic receptors. Epinephrine affects adrenergic receptors (symapthetic nervous system).
Which neurotransmitter receptor is present on the sarcolemma?
End of the muscle fiber I think it is the motor end plate
A term that means pertaining to mimicking or copying the effect of the sympathetic nervous system?
Drugs called 'sympathomimetics'. Their mechanism of action is primarily on adrenergic receptors (i.e., the receptors that normally bind adrenalin).
Where are alpha 1 receptors located?
peripheral blood vesels
If a cell has alpha adrenergic receptors is it sensitive to norepinephrine?
If a cell has α-adrenergic receptors, it is sensitive to
Stimulation of alpha-adrenergic receptors results in?
constriction of the blood vessels
How do alpha and beta receptors differ?
Affinity for different agonists, their locations throughout the body, the effects produced from their activation and supression. Presuming your talking about adrenergic receptorsAlpha adrenergic receptors & beta adrenergic receptors produce vasoconstriction and vasodilation respectively.
What are the 4 types of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2
Neurotransmittor for the sympathetic nervous system?
The neurotransmitter for sympathetic nervous system is norepinephrine (or also called noradrenaline) that acts on adrenergic receptors of the effector organ (alpha 1, beta 1, beta 2 receptors). The adrenergic receptors are G-protein coupled.
What is an alpha-blocker?
An alpha-blocker is a drug which blocks a1-adrenergic receptors in arteries and smooth muscles, and is used to treat benign prostatic hyperplasia and prostatitis.
Why is epinpherine a vasoconstrictor and bronchodilator?
coz it works on alpha 1 adrenergic receptors in small blood vessels causing vasoconstriction and hence increase blood pressure (contrary to its action on skeletal muscles) it is also working on B2 adrenergic receptors causing bronchodilation
What adrenergic receptors are present on the rabbit ileum?
B2 receptors
What adrenergic receptors increase cAMP levels?
beta receptors
Do epinephrine use g-protein linked receptors?
Epinephrine or more commonly known as adrenaline bind to adrenergic receptors. These adrenergic receptors are a type of G-protein coupled receptors
B adrenergic receptors are the only receptors found on the heart true or false?
False
What receptors bind norepinephrine and epinephrine?
adrenergic receptor
