Endocrine System: The endocrine system is a network of glands that release hormones into the bloodstream to regulate processes like metabolism, growth, reproduction, and homeostasis.
The Hypothalamus Pituitary Complex: The hypothalamus and pituitary gland form a key regulatory complex that controls endocrine function via releasing and inhibiting hormones that act on the anterior and posterior pituitary.
The Anterior Pituitary Complex: The anterior pituitary produces hormones including ACTH, TSH, GH, FSH, LH, and prolactin, regulated by hypothalamic signals and responsible for growth, metabolism, and reproductive function.
