located on smooth muscle cells.Heart
produce muscle contraction |
|
|
á2 receptors act on ...
|
the brain as a negative feedback causing less norepinephrine to be released.
|
|
|
â1 receptors act on...
|
the heart. Smooth muscle They cause the formation of cAMP, a second messenger. They increase heart rate and contractility.
|
|
|
â2 receptors are in
|
in the bronchi. They cause dilation.
|
|
|
Muscarinic receptors...
|
Excite or inhibit and increase Ca++ into the cell to initiate contraction of smooth muscle.
They increase secretion of exocrine glands. |

Norepinephrine receptor action
|
Alpha 2 adrenergic agonist

|
Albuterol acts on...
|
Beta2 agonist
|
causing bronchodilation
|
|
Clonidine
|
Classification: Adrenergic alpha 2 agonist
Use: Centrally acting to decrease blood pressure. Used in alcohol withdrawal to reduce blood pressure response. Decreases release of norepinephrine in the brain and decreases the effect of the sympathetic nervous system. |

Beta 1 receptors act on...
|
cardiac. Stimulation increases heart rate and contractility
|
|
|
Beta 2 receptors are
|
in the bronchi. They cause dilation

Used To maintain NSR after conversion. Ventricular ectopic beats and Ventricular tachycardia
|
Slows conduction velocity. Prolongs refractory period
