The key difference between positive and negative feedback is their response to change: positive feedback amplifies change while negative feedback reduces change. This means that positive feedback will result in more of a product: more apples, more contractions, or more clotting platelets
The anterior pituitary receives signalling molecules from the hypothalamus, and in response, synthesizes and secretes seven hormones.
The posterior pituitary does not produce any hormones of its own; instead, it stores and secretes two hormones made in the hypothalamus.
the endocrine system uses chemical signaling (hormones, produced by glands) while the nervous system uses electrical signaling (neural impulses).
The primary reproductive organs, or gonads, consist of the ovaries and testes. These organs are responsible for producing the egg and sperm cells gametes), and hormones.
