How do adrenergic agonists affect heart rate and the bronchial muscles?
Adrenergic agonists speed up the heart rate and relax the bronchial muscles.
Which neurotransmitters speed up or slow down the heart rate?
The chemical neurotransmitter, Acetylcholine attaches to what is known as a muscarinic receptor. This brings the body back to "rest and digest", and relaxes it from the "fight or flight" response.
Activation of which kind of receptor causes heart rate to increase?
beta-one receptor
Does the electrical activity of the heart precede mechanical activity?
Yes. It is the electrical activity that stimulates the mechanical activity.
Which is the neurotransmitter for the sympathetic nervous sytem that increases the heart rate to prepare for exercise of the fight or flight response?
epinephrine

How beta adrenergic drugs cause diabetes?
increase bp and heart rate
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.
Activation of which kind of receptor causes heart rate to increase?
beta-one receptor
B adrenergic receptors are the only receptors found on the heart true or false?
False
What neurotransmitter dercreases heart rate?
acetylcholine~ACh
Which type of receptor is common in the heart?
beta
What neurotransmitter causes low blood pressure?
The neurotransmitter epinephrine can cause the blood pressure to become low. This neurotransmitter also regulated the heart rate. It is often controlled by stress.
How do doctors treat angina?
Anti anginal medications include nitrates such as nitroglycerin and beta adrenergic receptor blockers (beta blockers). Nitrates work by causing dilation of the arteries of the heart so more blood can flow through to bring oxygen to the heart. B blockers work by decreasing the work-load of your heart and decreasing the amount of oxygen required by your heart to do the same amount of work
What neurotransmitter causes the heart rate to increase?
Beta 1 receptors
