Neurohormones are chemical messengers produced by the hypothalamus and released into the bloodstream. They play a crucial role in regulating various bodily functions, including stress response, growth, and metabolism. Unlike traditional hormones, which are secreted by glands, neurohormones are released directly from nerve cells, allowing for rapid communication between the nervous system and the endocrine system. Examples of neurohormones include oxytocin, which influences social bonding and childbirth, and vasopressin, which helps regulate water balance in the body. These substances are essential for maintaining homeostasis and responding to environmental changes, highlighting the interconnectedness of the nervous and endocrine systems.
