Serratus Posterior Superior Muscle

Introduction The serratus posterior superior muscle is found in the back’s intermediate compartment. It has a slender, rectangular shape and is placed deep in the upper back, close to the rhomboid muscles. The rib cage is raised by the serratus posterior superior muscle and lowered by the serratus posterior inferior muscle. When forced breathing is…
