Hormones: Current Scientific Definition
How does the current scientific definition of a 'hormone' differ from the classical definition?
How does the current scientific definition of a 'hormone' differ from the classical definition?
- Classical Definition: A chemical produced by an endocrine gland, released into the blood, and transported to a distantly located target organ.
- Current Scientific Definition: Hormones are strictly non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts.

Neural vs. Endocrine Coordination
What is the fundamental physiological difference between neural coordination and endocrine coordination?
What is the fundamental physiological difference between neural coordination and endocrine coordination?
- Neural Coordination: Provides a point-to-point, rapid coordination among organs. The response is fast but strictly short-lived.
- Endocrine Coordination: Carried out by hormones. It provides continuous, long-lasting regulation and integration of cellular functions across the body.
