Cranial nerve pathways are really important for how we sense things and move our bodies. Let’s break it down simply:

Sensory Functions:

• These pathways help us take in information, like what we smell and taste.
• For example, the olfactory nerve (which is CN I) helps us smell things. The optic nerve (CN II) is responsible for our vision.

Motor Functions:

• They also help control movements, like making facial expressions and moving our eyes.
• For instance, the facial nerve (CN VII) is what helps us move our face. The trochlear nerve (CN IV) helps us move our eyes.

Thanks to these pathways, we can do everyday activities easily!
