Neurology | Cranial Nerves: Overview

Official Ninja Nerd Website: https://ninjanerd.org Ninja Nerds! Join us in this lecture where Professor Zach Murphy will be providing a comprehensive overview of the cranial nerves. We begin by identifying the twelve cranial nerves (CN I–XII) in order, detailing their names, general functions, and whether they are sensory, motor, or mixed. We also review their anatomical origins from the brain or brainstem and their major pathways. This section lays the groundwork for understanding how these nerves control sensory perception, motor coordination, and parasympathetic activity in the head, neck, and beyond. We then explore the key sensory functions of the cranial nerves, including vision, smell, hearing, balance, taste, and general facial sensation. Each sensory role is paired with its corresponding nerve and central connections, emphasizing how the brain processes these inputs. This is followed by a breakdown of the motor functions, covering voluntary movements such as eye tracking, facial expression, mastication, swallowing, tongue movement, and involuntary reflexes like the corneal reflex and pupillary light reflex. Finally, we integrate the cranial nerves into a functional perspective, explaining how they work together in complex reflex arcs and coordinated behaviors. We connect their roles to clinical relevance by describing how lesions at different anatomical levels can produce distinct neurological deficits. This overview will prepare you for more in-depth, nerve-specific discussions in upcoming lectures. Enjoy the lecture and support us below!
