The Serratus Posterior Superior is a muscle that is a part of the human musculoskeletal system. It is located in the upper back region, extending from the spinous processes of the lower cervical and upper thoracic vertebrae to the second to the fifth ribs.
The name "Serratus Posterior Superior" is derived from Latin, with "Serratus" meaning "saw-like" or "serrated," "Posterior" referring to its location at the back of the body, and "Superior" indicating its upper placement. This muscle is rectangular in shape and is situated in the deep layer of the thoracic back muscles.
The primary function of the Serratus Posterior Superior is to elevate the upper ribs during inhalation, aiding in the expansion of the thoracic cavity to facilitate breathing. It also contributes to the stabilization of the upper back and helps maintain proper posture.
Injury or dysfunction of the Serratus Posterior Superior can lead to symptoms such as localized pain in the upper back, restricted movement, and difficulties in deep breathing. Stretching exercises, targeted strengthening exercises, and physical therapy techniques may be employed to treat injuries or alleviate discomfort associated with this muscle.
Understanding the anatomy and functionality of the Serratus Posterior Superior is crucial for healthcare professionals, physiotherapists, athletes, and individuals seeking to improve their posture and optimize their respiratory function.
