One major difference between the stretch receptor cells of muscle fibers and the chemoreceptors found in the nasal cavity is that only stretch receptors contain A) stretch-gated Na⁺ channels on their dendrites. B) stretch-gated Na⁺ channels on their axon hillocks. C) receptor proteins that generate action potentials. D) many different types of G protein-linked receptors. E) G protein-linked receptors that activate a second messenger.

Question

Quizplus · Accepted Answer

Stretch receptors contain stretch-gated Na⁺ channels on their dendrites, which are activated by mechanical deformation, unlike chemoreceptors in the nasal cavity.
