Agonist




An agonist is a muscle that is contracting during a movement and which is primarily responsible for the movement of a certain body part. More specifically, it is a muscle capable of increasing torque in the direction of a limb's movement, and thus produce a concentric action. Opposed by another body part, the antagonist. Also see Muscle Roles: What is an Agonist, Antagonist, Stabilizer, Fixator or Neutralizer Muscle?

Also, in physiology and pharmacology, an agonist is a substance that binds to a neurotransmitter's receptors and so mimics the neurotransmitter's response. Drugs that are agonists are meant to mimic the body's own regulatory system.
