Olfactory Nerve pathway 2. - Axons of olfactory bulb neurons extend posteriorly and form olfactory tracts. - Some axons of olfactory tract project to the primary olfactory area of the cerebral cortex (where awareness of smell begins). - Other axons project to the limbic system and hypothalamus. Provide physical support, nourisment and electrical insulation for olfactory receptors. - Help detoxify chemicals that come into contact with olfactory epithelium. - Innervated by autonomic neurons within branches of facial (VII) nerve which is stimulated by specific chemicals.
