The neuroendocrine system is a complex network that combines the functions of the nervous system and the endocrine system. It involves the release of hormones from glands in response to signals from the brain, particularly the hypothalamus. These hormones help regulate various bodily functions, including growth, metabolism, and stress responses. Key components of the neuroendocrine system include pituitary gland, adrenal glands, and thyroid gland. The system plays a crucial role in maintaining homeostasis, which is the body's ability to maintain a stable internal environment. By coordinating hormonal signals and neural activity, the neuroendocrine system ensures that the body responds appropriately to changes in its environment.
