The term "nervus occipitalis minor" refers to the lesser occipital nerve, one of the branches of the greater occipital nerve. This nerve is responsible for providing sensory innervation to the skin in the lower part of the back of the head. While there are no direct synonyms for "nervus occipitalis minor", it is closely related to the greater occipital nerve, which is sometimes referred to as the "nervus occipitalis major". Both nerves are crucial in transmitting sensory information and any discomfort or dysfunction in these nerves can lead to head and neck pain.
