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.
Are beta receptors adrenergic and do they bind to norepinephrine and epinephrine?
Cholinergic
What are some examples of beta-adrenergic blocking agents?
Beta-adrenergic blocking agents include propranolol (Inderal), atenolol (Tenormin), and pindolol (Visken).
What are beta-1 receptors found?
There are at lest 3 types of beta receptors and they are found in different organs. Beta-1 (β1) receptors are found in the heart, eye, and kidneys while beta (β2) receptors are found in the lungs, gastrointestinal tract, liver, uterus, blood vessels, and skeletal muscle. The third type, beta (β3) receptors are found in fat cells.
How a beta receptor antagonist causes a decrease in blood pressure?
To understand how beta adrenergic blockade lowers blood pressure, you need to understand a little physiology. Beta receptors are present in many different places in the body: the heart, the blood vessels, the kidneys, the lungs, the muscles, etc. They perform different tasks in each different place as well, and there are different classes of receptors. For instance, in the heart, the receptors are called beta-1 receptors and they increase the rate of firing of the SA node (chronotropy), increases cardiac conduction velocity (dromotropy) and increase the strength with which the heart beats (inotropy). In the arterioles, the receptors cause dilatation of the vessels and are called beta-2 receptors. In the kidneys, beta-1 receptors increase renin output from the juxtamedullary cells when stimulated. Renin is an enzyme that produces a potent vasocontrictor when it activates the angiotensin cascade. Now, how does beta antagonism lower blood pressure. First, in the heart, beta blockade causes a slowing of the heart rate and stroke volume, effectively decreasing cardiac output. In the kidneys, beta blockade decreases renin release, which decreases the amount of systemic vasoconstrictors in the body. These two effects cause the blood pressure to decrease over time.
What adrenergic receptors increase cAMP levels?
beta receptors
How do alpha and beta receptors differ?

Are beta receptors adrenergic and do they bind to norepinephrine and epinephrine?
Cholinergic
Beta adrenergic blocking agents are used to?
Beta adrenergic agents serve as inhibitors that prevent beta adrenergic substances (neurotransmitters) such as epinephrine from binding to beta adrenergic receptors (beta 1, beta 2 and beta 3). This prevents the effects of the neurotransmitters thereby reducing blood pressure and heart rate.
What are the 4 types of adrenergic receptors?
alpha 1, alpha 2, beta 1, beta 2
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.
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 does propranolol work?
Propranolol acts on the beta-adrenergic receptors anywhere in the body, and has been used as a treatment for emotional anxiety and rapid heart beat.
Dilation and relaxation of the bronchioles are possible bcause of the presence of?
Beta 2 adrenergic receptors in lung tissue cause dilation of bronchioles via sympathetic stimulation.
What is Tenoretic?
It is a beta-adrenergic blocking drug
What are some examples of beta-adrenergic blocking agents?
Beta-adrenergic blocking agents include propranolol (Inderal), atenolol (Tenormin), and pindolol (Visken).
What is another name for beta blockers?
Beta blockers, also known as beta-adrenergic blockers
