Learning objective
Distinguish drug origin, psychoactive action, and naming without treating origin as a safety judgment.
Drug and psychoactive
The course uses drug for an exogenous chemical that affects bodily processes. Exogenous means introduced from outside the body; endogenous refers to chemicals produced within it, such as neurotransmitters and hormones. In this course framing, a psychoactive drug acts directly on the brain and can change mood, behavior, or consciousness.

Origin and names
Natural and synthesized describe origin, not whether a substance is safe. A brand name identifies a marketed product; a generic name identifies the drug chemical. The deck pairs Prozac with fluoxetine as a naming example. Keep origin, brain action, and naming as separate questions.
Supplemental visual
Origin asks whether something comes from outside the body or is produced within it. Brain action asks whether it is psychoactive in the course framing. Naming distinguishes a generic chemical name from a marketed brand. None of these labels alone establishes safety.
