D) receptor potentials

Quizplus · Accepted Answer

Encapsulated nerve endings are sensory receptors that respond to mechanical forces. When a mechanical force (such as pressure or vibration) is applied to the receptor, it deforms the receptor membrane and opens ion channels, which leads to a local change in membrane potential called receptor potential. This type of signal occurs in the dendrites of the encapsulated nerve endings. The other options (action potentials, neurotransmitter exocytosis, and postsynaptic potentials) are not applicable to this situation.
