Neurohumoral refers to the interplay between the nervous system and the endocrine system through chemical messengers. The nervous system communicates rapidly using electrical impulses and neurotransmitters, while the endocrine system uses hormones, which are released into the bloodstream and travel to target cells throughout the body. This communication system allows for complex regulation of physiological processes.

Neurohumoral mechanisms are involved in a wide range of bodily functions. For example, the stress response involves the nervous system activating the release of hormones like adrenaline and cortisol, which prepare the body for "fight or flight." The hypothalamus, a key brain region, plays a crucial role by bridging the nervous and endocrine systems. It receives neural signals and, in turn, releases hormones that control the pituitary gland, which then regulates other endocrine glands.

Examples of neurohumoral regulation include control of blood pressure, heart rate, metabolism, and reproductive functions. Neurotransmitters released at nerve endings can also act as hormones, diffusing into the bloodstream to exert systemic effects. Conversely, hormones can influence neuronal activity and brain function. This intricate feedback loop ensures that the body can adapt to changing internal and external conditions. Dysregulation of neurohumoral pathways can contribute to various diseases and disorders.
