<prompt> Which of the following nuclei is involved in both light reflex and accomodation reflex?Pretectal nucleusEdinger - Westphal nucleusSuprachiasmatic nucleusSupraoptic nucleus  <response>: Explanation: - Pupillary light reflex: Visual pathway - pretectal nucleus - Edinger Westphal nucleus - constriction of the pupil. NOTE: Pretectal nucleus is connected to E-W nucleus bilaterally, causing contralateral pupil to also constrict indirect light reflex. Accommodation reaction: Visual pathway - visual coex blurred image of a near object - E-W nucleus - changes of accommodation.
