Chapter 18 Study Guide: The Endocrine System 1. Choose (place an X) whether the characteristic applies to the Nervous System or Endocrine System (or both) Characteristic Nervous Endocrine Action is generally brief (lasting milliseconds). Action generally lasts longer (seconds to days). Mediator molecules delivered to target by bloodstream. Action potentials trigger release of mediator molecules at synapse with target. Target cells require specific protein receptor for mediator molecule. Stimulates skeletal muscle contractions. Influence is much broader; will regulate virtually all types of body cells. Controls growth & development and regulates reproductive systems. Maintains internal environments (homeostasis) Mediator molecules include acetylcholine, glutamate, norepinephrine, serotonin Mediator molecules include aldosterone, melatonin, insulin, calcitonin
