Beside above, what is the serratus posterior? The serratus posterior muscles are two thin, superficial back muscles which lie above the intrinsic back musculature. The serratus posterior inferior muscle originates from the spinous processes of the T11 to T12 thoracic vertebrae and has its insertion on the four lower ribs.
Also Know, what is the function of the serratus posterior superior?

Where is the serratus posterior located?
The serratus posterior inferior muscle is located in the mid to lower back and forms a V-shape.
