Tonic Receptors: The Significance of Constant Sensory Information for the Central Nervous System

___ receptors adapt slowly, constantly alerting the CNS of the stimulus with action potentials

Tonic

The receptors that adapt slowly are known as tonic receptors. These types of receptors are constantly alerting the central nervous system of the stimulus with action potentials. Tonic receptors maintain the firing of action potentials for the duration of the stimulus, thus providing the CNS with a continuous stream of sensory information.

Tonic receptors are important in providing us with information about the state of our bodies and the environment around us. Examples of tonic receptors include muscle spindles that detect changes in muscle length and vestibular hair cells that detect changes in head position and movement.

Overall, tonic receptors play a critical role in maintaining sensory homeostasis and keeping the CNS informed of continuous changes in the environment.
