Explain the term Light reflex - Neuronal pathways

The neuronal pathway for light reflex can be afferent and efferent. In the afferent pathway, the pupillary fibres begin in the retina and follow to the pretectal area where synapse takes place. From that location, the fibres are projected to the Edinger- Westphal nucleus. In the efferent pathway, the iris is innervated by the Edinger Westphal nucleus. From the Edinger-Westphal nucleus in the midbrain, the fibres go to the 111 cranial nerve and then to the sphincter pupillae.
