What is the origin of serratus posterior superior?

Explanation:
Serratus posterior superior starts from the nuchal ligament and the spinous processes of the seventh cervical to the third thoracic vertebrae. This proximal attachment sits at the upper back near the neck, which fits its role in elevating the upper ribs during inspiration and helping expand the thoracic cage. The nuchal ligament with those specific spinous processes is distinctive to this muscle, setting it apart from the lower back counterpart that originates from T11–L2 for serratus posterior inferior, or from other regions that don’t match its location.
