How do sensory systems work?

well, sight works when the lens focuses light onto the retina where different colours are applied along the optic nerve where the image is flipped the right way up by the cerrablellum. you hear things when the vibrations that make up sound vibrate your eardrum which is connected to the cochlea which houses nerve ending to translate the vibrations back into sound. taste works when bits of food dissolved in saliva come into contact with taste bits that make up a profile of the taste and send it to the brain. smell works when tiny particles in the air reach the smell receptors. touch works when the nervous system contains nerves which send profiles of textures to the cerebral cortex.
