General senses often contribute to the sense of touch, as described above, or to proprioception (body position) and kinesthesia (body movement), or to a visceral sense, which is most important to autonomic functions. This occurs when a stimulus is detected by a receptor which generates a graded potential in a sensory neuron. photoreceptor: A specialized neuron able to detect and react to light. THE GENERAL SENSES RECEPTORS 1. Receptor cells can be further categorized on the basis of the type of stimuli they transduce. Sensory information from the body that is conveyed through spinal nerves will project to the opposite side of the brain to be processed by the cerebral cortex.
