There are currently three known types of photoreceptor cells in mammalian eyes: rods, cones, and photosensitive retinal ganglion cells. The two classic photoreceptor cells are rods and cones, each contributing information used by the visual system to form a representation of the visual world, sight.
Many equilibrium receptors give signals of two typesâstatic ones, associated with body position, and dynamic ones, associated with acceleration. In vertebrates, including man, the organs of equilibrium are represented by the vestibular apparatus, whose receptor is located in the inner ear.any equilibrium receptors give signals of two typesâstatic ones, associated with body position, and dynamic ones, associated with acceleration.
