It is Polysynaptic
I would call it an organic reflex.
Pupillary light reflex is autonomic.
Photopupillary reflex is pupillary constriction in response to light.
The receptor is the retina of the eye; smooth muscle of the iris is the effector. They both change simultaneously because the pupillary light reflex is contralateral.
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.

Pupillary light reflex is autonomic.
pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system

autonomic
The two are different because of what triggers the reflex. While the patella is triggered through the sense of touch, the pupillary is triggered through light.
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.
The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.
The patellar reflex is ipsilateral. If the stimulus is applied to left knee cap, the left knee responds. On the other hand, if the right knee were to respond to a left knee stimulus, the response would be considered contralateral.
You probably mean the pupillary reflex. It is the reflex responsible for your pupils constricting (becoming smaller) when exposed to light and dilating (becoming bigger) when you walk into a dark room.
Type your answer here... Constriction of the pupils is inability to adapt to changing light.
