Does the zygomaticus major attach to the modiolus?

1. Yes

2. No

3. Only in specific conditions

4. It depends on individual anatomy

The correct answer is: Yes

The zygomaticus major is a facial muscle known for its role in smiling, as it elevates the corners of the mouth. It originates from the zygomatic bone and inserts into the modiolus, a fibrous junction at the corner of the mouth where several facial muscles converge. This connection to the modiolus is significant because it allows for coordinated movement during facial expressions. Given that the attachment is a standard anatomical feature of the zygomaticus major, the correct answer is that it does indeed attach to the modiolus. This attachment point plays a critical role in facial dynamics, enabling the muscle to effectively contribute to expressions of happiness and joy. The modiolus itself serves as a strategic site for muscle interaction, enhancing the versatility and expressiveness of facial movements.
