AP PSYCHOLOGY

Detailed explanation-1: -Hormone production and release are primarily controlled by negative feedback. In negative feedback systems, a stimulus causes the release of a substance whose effects then inhibit further release. In this way, the concentration of hormones in blood is maintained within a narrow range.

Detailed explanation-2: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released.

Detailed explanation-3: -Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.

Detailed explanation-4: -Positive and negative feedback mechanisms are two different types of feedback mechanisms. Positive feedback stimulates and increases hormone secretion. Negative feedback stops and inhibits the hormone from being produced.

Detailed explanation-5: -A humoral stimulus refers to the control of hormone release in response to changes in extracellular fluids such as blood or the ion concentration in the blood.
