Small Muscle, Big Impact: The Secret Behind Our Smiles
Scientists have highlighted the crucial role of the levator anguli oris muscle in human communication. This small but mighty muscle, located on either side of the mouth, is responsible for forming one of our most universal expressions: the smile.
The levator anguli oris muscle, originating in the maxilla bone and inserting into the modiolus at the mouth's corner, elevates the mouth's corners. This action creates the upward curve that signifies happiness, amusement, or even a polite grin.
The muscle's function is supported by the buccal branches of the facial nerve, which provide sensory innervation. It receives oxygenated blood from the facial artery, ensuring it's well-supplied for its constant use in our daily interactions.
Dr. Paul Tessier, a renowned neurosurgeon, extensively studied and described the levator anguli oris muscle's role in forming the smiling expression. His work has deepened our understanding of the intricate relationship between our facial muscles and nonverbal communication.
The levator anguli oris muscle, with its origins in the maxilla bone and insertions at the mouth's corner, is vital for expressing our emotions through smiles. Its study has provided valuable insights into the complex interplay between our facial muscles and communication, with Dr. Paul Tessier's work being particularly influential in this field.
