WebThe rods, containing rhodopsin photoreceptors, are substantially more light-sensitive than the cones and are therefore used for vision at low light levels, e.g. at night with a minimum amount of illumination, where the cones hardly deliver any usable signals. WebFigure 13.1.1 – Receptor Classification by Cell Type: Receptor cell types can be classified on the basis of their structure. Sensory neurons can have either (a) free nerve endings or (b) encapsulated endings. Photoreceptors in the eyes, such as rod cells, are examples of (c) specialized receptor cells. These cells release neurotransmitters ...
