Receptor fits in at least three different disciplines, including:
- "Sensory receptor, in physiology, any structure which, on receiving environmental stimuli, produces an informative nerve impulse
- "Receptor (biochemistry), in biochemistry, a protein molecule that receives and responds to a neurotransmitter, or other substance
- "Immune receptor, a special case of biochemical receptor that occurs on the surface of immunocytes and binds to antigens."

What else can I help you with?
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.
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.
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).
The adrenergic receptor that causes bronchodilation when stimulated is?
The beta2 adrenergic receptor is primarily responsible for bronchodilation when stimulated by agonists such as beta2-adrenergic agonists like albuterol. Stimulation of these receptors leads to smooth muscle relaxation in the airways, resulting in increased airflow and improved breathing.
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.
B adrenergic receptors are the only receptors found on the heart true or false?
False. While beta-adrenergic receptors are commonly found in the heart, there are also other types of receptors present, such as alpha-adrenergic receptors and muscarinic receptors, that play a role in regulating heart function.
What receptors bind norepinephrine and epinephrine?
Norepinephrine and epinephrine primarily bind to adrenergic receptors in the body, specifically alpha and beta adrenergic receptors. These receptors are part of the sympathetic nervous system and facilitate the body's "fight or flight" response.
Epinephrine has an affinity to what recepotor?
Epinephrine has an affinity for adrenergic receptors, particularly alpha and beta adrenergic receptors in the sympathetic nervous system.
Is epinephrine an adrenergic agonist?
Yes, epinephrine is an adrenergic agonist. It acts on adrenergic receptors in the body, particularly on alpha and beta adrenergic receptors, to increase heart rate, dilate airways, and constrict blood vessels.
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.
Do epinephrine use g-protein linked receptors?
Yes, epinephrine binds to G-protein coupled receptors, specifically the α and β adrenergic receptors. Activation of these receptors leads to various physiological responses such as increased heart rate, bronchodilation, and vasoconstriction.
What adrenergic receptors are present on the rabbit ileum?
The rabbit ileum primarily possesses α1-adrenergic receptors, which are responsible for mediating smooth muscle contraction. Stimulation of these receptors by adrenaline or noradrenaline can lead to increased motility in the rabbit ileum.
Which receptor sites epinephrine stimulate?
Epinephrine stimulates adrenergic receptors, specifically alpha and beta adrenergic receptors. These receptors are found on various tissues and organs throughout the body, leading to effects such as increased heart rate, bronchodilation, and vasoconstriction.
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).
Are beta receptors adrenergic and do they bind to norepinephrine and epinephrine?
Yes, beta receptors are adrenergic receptors, meaning they bind to adrenaline (epinephrine) and norepinephrine. There are three subtypes of beta receptors: Beta-1, Beta-2, and Beta-3, each with different functions and tissue distributions.
Stimulation of alpha-adrenergic receptors results in?
constriction of the blood vessels
