Neuroendocrine cells are specialized cells that have characteristics of both nerve cells and endocrine cells. They produce and release hormones in response to signals from the nervous system, playing a crucial role in regulating various bodily functions, such as metabolism and stress responses. These cells are found in various organs, including the lungs, gastrointestinal tract, and pancreas. These cells respond to neurotransmitters and can release hormones directly into the bloodstream. This unique function allows them to act as a bridge between the nervous system and the endocrine system, influencing processes like growth, mood, and digestion. Their proper functioning is essential for maintaining homeostasis in the body.
