Controls the superior oblique muscle of the eye (downward and inward movement). Trigeminal
Responsible for transmitting visual information from the eyes to the brain. Oculomotor your12 nervesblogspotcom
To truly understand what platforms like your12nerves.blogspot.com help students study, we must look at the layout of these 12 critical structures. Unlike spinal nerves that emerge from the spinal cord, cranial nerves emerge directly from the brain and exit through various foramina (holes) in the cranium. They are numbered using Roman numerals (I through XII) based on their location from the front of the brain to the back. Primary Function Olfactory Governs your sense of smell. CN II Optic
