What primarily distinguishes direct hormones from tropic hormones?
Understand the Problem
The question is asking about the key differences between direct hormones and tropic hormones, specifically what primarily sets them apart in their function and characteristics.
Answer
Tropic hormones stimulate other glands; direct hormones act on target tissues.
Tropic hormones stimulate endocrine glands to release other hormones, whereas direct hormones act directly on target tissues to elicit a response.
Answer for screen readers
Tropic hormones stimulate endocrine glands to release other hormones, whereas direct hormones act directly on target tissues to elicit a response.
More Information
Tropic hormones are crucial in hormone cascades as they help regulate the secretion of hormones from other glands, creating a cascade effect. Direct hormones, on the other hand, are involved in immediate physiological changes by acting directly on their specific target tissues.
Tips
A common mistake is confusing the target action site: Tropic hormones do not have direct physiological effects but work through other glands.
