Tonic Function
Tonic function refers to a continuous, baseline level of activity in the nervous system that helps maintain stability and readiness. It provides ongoing support to muscles, organs, or neural pathways, ensuring they stay at a certain level of alertness or tension. For example, in the nervous system, tonic activity keeps muscles slightly contracted to maintain posture, while in brain function, it sustains alertness and focus. This steady activity allows the system to respond promptly to changes or stimuli, maintaining balance and overall function without significant fluctuations.
