Question

Which statement correctly describes tonic receptors and their role in the body's sensory system?

Options:

A) Tonic receptors provide a sustained response with little or no adaptation.
B) Phasic receptors provide a sustained response with little or no adaptation.
C) Nociceptors and most proprioceptors are phasic receptors.
D) Tonic receptors provide a brief response and quickly adapt to stimuli.

Answer 1

The correct statement about A.tonic receptors is that they provide a sustained response with little or no adaptation, allowing the body to maintain awareness of a stimulus over time.

Step-by-step explanation:

The statement that correctly describes tonic receptors and their role in the body's sensory system is A) Tonic receptors provide a sustained response with little or no adaptation. Tonic receptors are sensory receptors that deliver a continual response to a stimulus over a prolonged period of time and adapt very slowly if at all. This type of response allows the body to maintain awareness of a stimulus over time, such as the feeling of clothing on the skin or maintaining a muscle contraction to hold a posture.

Phasic receptors, on the other hand, are known to provide a brief response to a stimulus and quickly adapt. These receptors signal the onset or the change in a stimulus rather than providing a sustained response. An example of a phasic receptor is the Meissner's corpuscle, which is sensitive to changes in texture or slow vibrations but quickly adapts once the stimulus becomes constant.
