The movements of the human nose are controlled by groups of facial and neck muscles that are set deep to the skin; they are in four (4) functional groups that are interconnected by the nasal superficial aponeurosis — the superficial musculoaponeurotic system (SMAS) — which is a sheet of dense, fibrous, collagenous connective tissue that covers, invests, and forms the terminations of the muscles.
