Olfactory Nerves I Primary function Special sensory smell Olfactory Epithelium Visceral ResponseDuring breathing air molecules attach to the olfactory mucosa and stimulate the olfactory receptors of cranial nerve I and electrical activity is transduced into the olfactory bulb Olfactory bulb cells then transmit electrical activity to other parts of the central nervous system via the olfactory tract which helps us to smell the surroundings Optic Nerves II Primary function Special sensory vision Retina of eye Somatic ResponseLight strikes the rod and cone cells and electrical impulses are transduced and transmitted to the bipolar cells The bipolar cells in turn transmit electrical activity to the central nervous system through the optic nerve which helps to see different colors Oculomotor Nerves III Primary function Motor eye movements Intrinsic eye muscles Somatic motor function These nerve axons will arise from the oculomotor nucleus and innervate skeletal muscles associated with the eye There are seven extrinsic eye muscles muscles that lay outside of the eye itself that move the superior eyelid and the eyeball Five of them are innervated by the oculomotor nerve Visceral motor function See Answer
