The primary function of neuroendocrine granules is to store and secrete hormones and neurotransmitters in a regulated manner. Upon receiving a specific stimulus, such as a neural signal or a change in the cellular environment, the granules fuse with the plasma membrane and release their contents into the extracellular space. This process, known as exocytosis, allows the granules to deliver their bioactive substances to target cells, thereby influencing various physiological functions such as metabolism, growth, and stress responses.
