MICROANATOMY

Detailed explanation-1: -A positive feedback loop in the endocrine system is when release of a hormone initiates actions that lead to an additional release of that hormone. Unlike a negative feedback loop, a positive one is not looking to reach homeostasis (stability).

Detailed explanation-2: -Oxytocin is one of a few hormones that have a positive feedback loop. This means that the release of oxytocin leads to actions that stimulate your pituitary gland to release even more of it.

Detailed explanation-3: -In positive feedback, rising levels of hormones feedback to increase hormone production. During most of the menstrual cycle, estrogen and progesterone provide negative feedback to the hypothalamus and pituitary gland. This keeps their levels more or less constant.

Detailed explanation-4: -Negative feedback keeps the concentration of a hormone within a relatively narrow range and maintains homeostasis. Very few endocrine hormones are regulated by positive feedback loops. Positive feedback causes the concentration of a hormone to become increasingly higher.
