Most animals, including humans, can sense impulses via a particular sensory receptor.
Chemoreceptors, mechanoreceptors, and thermoreceptors are examples of sensory receptors.
In one, a neuron collaborates with a sensory receptor, which is a cell or cell process that is trained to engage with and recognize a certain stimulus.
Stimulation of the sensory receptor activates the accompanying afferent neuron, which transmits stimulus information to the central nervous system.
