Adrenergic receptors

Adrenergic receptors: These are nerve endings of effector tissues, most of which can be excited by norepinephrine and/or epinephrine and adrenergic drugs.

Adrenergic nerve activity

Adrenergic nerve activity: Sympathomimetic amine activity

Adrenergic amines

Adrenergic amines: Those agents which have similar activity as that induced by adrenergic nerve activity for example epinephrine and ephedrine.

Adrenergic

Adrenergic: Those fibers or neurons that produce or activate norepinephrine and related agents.

Adipose tissue

Adipose tissue: It refers to the connective tissues that stores fat.

Adenylyl cyclase

Adenylyl cyclase: It is enzyme acting on ATP to form 3, 5-cyclic AMP plus pyrophosphate. It is an important step in the regulation and formation of second messengers. Adenylyl cyclase is the former name for adenylate cyclase.

Action potential

Action potential: It is a temporary difference of electrical potential between inside and outside of membrane of a cell during activity i.e. during transmission of nerve impulse.
