Trace the olfactory pathway, beginning at the olfactory epithelium
A) Axons from the olfactory epithelium bundle together and travel along the olfactory tract. Axons from the tract then synapse at the olfactory bulb. Axons from the olfactory bulb travel to the olfactory cortex, thalamus, and portions of the limbic system.
B) Axons from the olfactory epithelium bundle together and travel along the olfactory tract. Axons from the olfactory tract go to the olfactory cortex, hypothalamus, and portions of the ventricles. Then the axons from those regions synapse again at the olfactory bulb.
C) Axons from the olfactory epithelium bundle together and synapse at the olfactory bulb. Axons from the olfactory bulb travel directly to the olfactory cortex, olfactory association area, and the epithalamus.
D) Axons from the olfactory epithelium bundle together and synapse at the olfactory bulb. Axons from the olfactory bulb travel along the olfactory tract to the olfactory cortex, hypothalamus, and portions of the limbic system.
E) Axons from the olfactory epithelium bundle together and synapse at the olfactory bulb. Axons from the olfactory bulb travel along the olfactory tract to the olfactory cortex, basal nuclei, and portions of the reticular formation.
