Does the zygomaticus major attach to the modiolus?

The zygomaticus major muscle is indeed attached to the modiolus, a fibrous junction located at the corner of the mouth where several muscle fibers converge. This anatomical connection plays a significant role in facial expressions, particularly in elevating the corners of the mouth, which contributes to facial expressions such as smiling.

The zygomaticus major originates from the zygomatic bone and its fibers extend downward and medially to insert into the modiolus. This attachment allows for coordinated movement of the lips and surrounding muscles, facilitating a range of expressions that are crucial for non-verbal communication. Understanding this anatomical relationship is essential for fields such as anatomy, dentistry, and facial aesthetics, as it highlights how different muscles contribute to facial movement and expression.

Other choices may imply possible reasons or alternative scenarios regarding the attachment, but the clear anatomical relationship between the zygomaticus major and the modiolus is well-established in human anatomy. Thus, affirming the attachment is accurate.
