Detailed explanation-1: -Sympathetic Nervous System SNS receptors include Alpha-1, Alpha-2, Beta-1, and Beta-2 receptors. Epinephrine and norepinephrine stimulate these receptors, causing the overall fight-or-flight response in various target organs.
Detailed explanation-2: -An agonist is a substance that binds to a receptor and triggers a response in the cell. An agonist is the opposite of an antagonist in the sense that while an antagonist also binds to the receptor, it fails to activate the receptor and actually blocks it from activation by agonists.
Detailed explanation-3: -An action potential occurs when a neuron sends information down an axon, away from the cell body. Neuroscientists use other words, such as a “spike” or an “impulse” for the action potential. The action potential is an explosion of electrical activity that is created by a depolarizing current.
