Which specific nerve receptors do Beta blockers block in the involuntary nervous system?

I actually have to take beta blockers for my heart condition. Basically what they do is block the release of noradrenaline from stimulated nerves in all parts of the body.


Places in which nerves are stimulated are the muscles, blood vessels, and the heart. I'm not sure if there are specific nerves involved other than those that excrete noradrenaline.

Beta-blockers block beta-adrenergic substances, such as adrenaline in the involuntary nervous system.

They slow down the heart rate, decrease the force of contractions in the heart muscles, and reduce blood vessel contractions.
