Answer:
All of the listed responses are correct.
Step-by-step explanation:
Stimuli in the environment activate specialized receptor cells in the peripheral nervous system. Different types of stimuli are sensed by various types of receptor cells. Receptor cells can be classified into types on three different criteria:
1.cell type
2.position,
3. function.
Receptors can be classified structurally on the basis of cell type and their position in relation to stimuli they sense. classification can be functionally on the basis of the transduction of stimuli, or how the mechanical stimulus, photo, or chemical changed the cell membrane potential. An exteroceptor is a receptor that is located near a stimulus in the surrounding environment, example is the somatosensory receptors that can be found in the dermis
