What are the properties of the alpha adrenergic receptors?
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.
Which type or receptors are located everywhere in the body except for the brain?
The alpha- and beta-adrenergic receptors are found throughout the body, including the cardiovascular system, smooth muscle, and glands. However, they are not typically located in the brain.
If a cell has alpha adrenergic receptors is it sensitive to norepinephrine?
Yes, a cell with alpha adrenergic receptors is sensitive to norepinephrine. Activation of alpha adrenergic receptors by norepinephrine can lead to various physiological responses, such as vasoconstriction, pupil dilation, and increased glycogen breakdown.
Where are pheromone receptors in humans located?
Pheromone receptors in humans are located in the nose, specifically in the olfactory epithelium.
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).
What are the types of alpha receptors?
There are two main types of alpha receptors: alpha-1 and alpha-2. Alpha-1 receptors are located in smooth muscle cells of blood vessels, causing vasoconstriction when activated. Alpha-2 receptors are located both presynaptically and postsynaptically in the central and peripheral nervous systems, regulating the release of neurotransmitters.
What are the properties of the alpha adrenergic receptors?
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.
What are the 4 types of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2

Where are most alpha-receptors sites?
kidney
Does clonidine bind to mu receptors?
Clonidine acts on alpha-2 receptors - I have never read that it has activity on mu receptors.
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.
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 kind of receptors are located in your taste buds?
Taste receptors type 1 (sweet), and type 2 (bitter).
What are the effects of alpha-1 receptor stimulation?
Stimulation of alpha-1 receptors causes vasoconstriction, leading to an increase in blood pressure and pupil dilation. It can also result in smooth muscle contraction in organs such as the bladder and intestine.
Stimulation of alpha-adrenergic receptors results in?
constriction of the blood vessels
