Cranial Nerve ll:Optic n. Arises from the retina of the eye Optic nerves pass through the optic canals and converge at the optic chiasm They continue to the thalamus where they synapse (lateral geniculate bodies From there,the optic radiation fibers run to the visual cortex Carrying afferent impulses for vision (special somatic afferents fiber) • Arises from the retina of the eye • Optic nerves pass through the optic canals and converge at the optic chiasm • They continue to the thalamus where they synapse (lateral geniculate bodies ) • From there, the optic radiation fibers run to the visual cortex • Carrying afferent impulses for vision (special somatic afferents fiber) Cranial Nerve II: Optic n
