Brushing against a doorway as you enter a room will trigger which type of sensory response?
A) Metabotropic
B) Chemoreceptor
C) Thermoreceptor
D) Mechanoreceptor
E) Second messenger cascade

Question

Quizplus · Accepted Answer

Brushing against a doorway as you enter a room would activate mechanoreceptors which are responsible for sensing mechanical stimuli such as pressure, stretching, and vibration. Metabotropic receptors and second messenger cascades are involved in cellular signaling pathways and would not be activated by physical contact. Chemoreceptors are responsible for sensing changes in chemical concentrations in the environment and thermoreceptors detect changes in temperature.
