Neuroendocrine cells are specialized cells that play a crucial role in the body's communication system. They combine features of both the nervous system and the endocrine system, meaning they can send signals through neurotransmitters and hormones. These cells are found in various organs, including the lungs, pancreas, and gastrointestinal tract, where they help regulate important functions like digestion and metabolism. When stimulated, neuroendocrine cells release hormones directly into the bloodstream, allowing them to influence distant organs. For example, they can help control the body's response to stress or regulate appetite. Their unique ability to bridge the nervous and endocrine systems makes them essential for maintaining overall health.
