Serratus posterior superior
Introduction
Overview
Overview
The Serratus posterior superior is a thin, quadrilateral muscle, situated at the upper and back part of the thorax.
It arises by a thin and broad aponeurosis from the lower part of the ligamentum nuchae, from the spinous processes of the seventh cervical and upper two or three thoracic vertebræ and from the supraspinal ligament.
Inclining downward and lateralward it becomes muscular, and is inserted, by four fleshy digitations, into the upper borders of the second, third, fourth, and fifth ribs, a little beyond their angles.
