AP PSYCHOLOGY

Detailed explanation-1: -Olfactory nerve fibers travel a short distance to an area in the upper part of your nose (olfactory bulb). Before reaching your olfactory bulb, the nerve fibers pass through your cribriform plate. This spongy, lightweight skull bone separates your nasal area from your brain.

Detailed explanation-2: -The olfactory nerve is the first cranial nerve (CN I). It is a sensory nerve that functions for the sense of smell.

Detailed explanation-3: -The olfactory nerve is sensory in nature and originates on the olfactory mucosa in the upper part of the nasal cavity. From the olfactory mucosa, the nerve (actually many small nerve fascicles) travels up through the cribriform plate of the ethmoid bone to reach the surface of the brain.

Detailed explanation-4: -The olfactory nerves are the only cranial nerves that are directly attached to the cerebrum without stopping at the thalamus. The other cranial nerves synapse at the thalamus.

Detailed explanation-5: -The olfactory nerve is the first cranial nerve and is instrumental in our sense of smell. The olfactory nerve contains only afferent sensory nerve fibers and, like all cranial nerves, is paired.
