Difference between agonist and antagonist?

Agonist works with the muscles, and the antagonist is the muscle working against it in a contraction. i.e. Bicep curl, the agonist is the Biceps brachii and the antagonist muscle is the triceps brachii.The word agonist means "producing an action" - an antagonist opposes that action. In medicine, an agonist binds to a receptor site and causes a response, often imitating the natural body reaction. An antagonist acts against this drug and blocks the response. for examples ramiels small balls and pubic hair
