What is the insertion point of the serratus posterior superior?

The insertion point of the serratus posterior superior muscle is indeed at the second to fifth ribs. This muscle originates from the nuchal ligament, spinous processes of the upper thoracic vertebrae, and the supraspinous ligaments. It plays an essential role in the elevation of the upper ribs during inhalation, contributing to the respiratory process. By inserting on these specific ribs, the serratus posterior superior effectively assists in expanding the thoracic cavity when breathing.

Understanding this anatomical detail helps in recognizing the muscle's function during respiration as well as its importance in the mechanics of the upper torso. This information is particularly useful for sports massage practitioners, as it aids in assessing and treating conditions associated with respiratory muscle function and upper back tension.
