The pupillary light reflex (PLR) is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retinal ganglion cells of the eye, thereby assisting in adaptation to various levels of lightness/darkness.he pupillary reflex pathway begins with the photosensitive retinal ganglion cells, which convey information to the optic nerve (via the optic disc). The optic nerve connects to the pretectal nucleus of the upper midbrain, bypassing the lateral geniculate nucleus and the primary visual cortex.
A reflex is an inbuilt mechanism (in our DNA). An automatic reflex  is important to protect the body. For example if you accidentally  place your hand on a hot stove, the re â¦ flex pulls your hand from the  heatsource faster than your brain could have made the desicion.ne important aspect of reflex action is to help protect us without  having to think. Reflex actions are involuntary and quick. They are  done to meet an emergency and occur â¦ at the level of the spinal  cord.
