Where is the greater occipital nerve located?

The greater occipital nerve is primarily located at the back of the head. This nerve is a branch of the second cervical nerve (C2) and is responsible for supplying the scalp at the posterior part of the head. It emerges from the spinal column and ascends to innervate areas on the back of the skull, providing sensation to the scalp extending from the occipital bone to the upper regions of the head. Understanding the anatomical position of the greater occipital nerve is essential for various medical and cosmetological practices, especially when addressing conditions related to headaches or scalp treatments.
