The anterior nasal spine plays a vital role in supporting the nasal septum, which is the structure that divides the nasal cavity into two nostrils. This bony projection is located at the base of the nose and serves as an anchoring point for the cartilage and bony elements of the nasal septum. A strong support system is essential for maintaining the structural integrity of the nasal passage and ensuring proper airflow and function of the nasal cavity.

While other options discuss various anatomical features of the facial structure, such as attachments for muscles or connections to sinuses, the primary and most critical function of the anterior nasal spine specifically relates to its support of the nasal septum. This is crucial in preserving the shape and alignment of the nose, which directly impacts respiratory health and overall appearance. The other functions, although relevant in the context of facial anatomy, do not underscore the primary importance of the anterior nasal spine as effectively as its role in supporting the nasal septum.
