SERRATUS POSTERIOR Meaning and
Definition
-
The term "Serratus Posterior" refers to a pair of muscles located in the human body. It consists of two distinct muscles: the Serratus Posterior Superior and the Serratus Posterior Inferior. Both muscles are classified as extrinsic muscles of the back and are situated deep to the rhomboid muscles.
The Serratus Posterior Superior muscle is found in the upper back region. It originates from the spinous processes of the seventh cervical and first few thoracic vertebrae. From there, it inserts into the superior borders of the second to fifth ribs. The primary function of the Serratus Posterior Superior is to elevate the ribs during deep inhalation. This muscle is crucial for the normal functioning of the respiratory system.
On the other hand, the Serratus Posterior Inferior muscle is located in the lower back region. It arises from the spinous processes of the lower two thoracic and upper two lumbar vertebrae. It then inserts into the lower borders of the lower four ribs. The main function of this muscle is to depress the ribs during exhalation.
Overall, the Serratus Posterior muscles play a vital role in the process of respiration, specifically in the elevation and depression of the ribs. They contribute to the overall movement and efficiency of the human respiratory system, aiding in the intake and expulsion of air from the lungs.

Etymology of SERRATUS POSTERIOR
The word serratus is derived from the Latin term serratus, meaning saw-shaped or serrated, which is itself derived from the verb serrare, meaning to saw. This Latin word describes the appearance of the muscle, which exhibits saw-like or serrated edges.
The term posterior comes from the Latin word posterior, meaning situated behind or subsequent. In anatomy, posterior refers to the back or the rear.
Therefore, serratus posterior literally translates to saw-shaped muscle situated behind or saw-shaped muscle at the back.
