receptor desensitization

Receptor desensitization is a process where cells become less responsive to a stimulus after prolonged exposure to a signal, such as a hormone or neurotransmitter. Imagine a light switch that eventually dims after being on for too long. This adaptation helps prevent overreaction and maintains balance in bodily functions. It ensures that cells don’t get overwhelmed and can still respond appropriately to changes in their environment. This mechanism is crucial for regulating processes like mood, pain perception, and immune responses.
