agonists

Muscles that contract

Agonists are substances that bind to receptors and trigger a biological response—they activate rather than block.

In pharmacology, a drug may be an agonist for certain receptors: Morphine is an opioid receptor agonist.

The term extends to muscles that contract to produce movement, opposed by antagonists.

In narrative, agonists are the principal characters driving the action, from the Greek word for competitor or actor.
