Which nerve runs from the base of the skull into the eyes and scalp?

The occipital nerve is the correct answer because it plays a crucial role in the sensory innervation of the scalp as well as the rear of the head and neck. It originates from the spinal nerves in the cervical region and extends upward, traveling from the base of the skull to the areas surrounding the eyes and scalp.

This nerve is significant in providing sensation to the scalp and may also be involved in headaches or certain pain syndromes experienced in that region. Understanding the function and pathways of the occipital nerve is essential in the context of chiropractic care, as well as in diagnosing and treating conditions that may involve cervical nerve root irritation.

The other options listed do not relate to the specified area of innervation. The sciatic nerve primarily serves the lower body, while the median and ulnar nerves are largely associated with the arm and hand. This distinction highlights the importance of recognizing which nerves correspond to specific anatomical regions and functions.
