- Short for "beta-adrenergic receptor blocker."

- Beta-adrenergic receptors are in the walls of smooth muscles around blood
- vessels and cardiac muscle. They receive neurotransmitter molecules from
- nerves of the sympathetic nervous system. This part of the nervous system
- controls *increases* in blood pressure, as well as other things. Blocking
- these receptors blocks the blood-pressure-increasing signals.
