As you study the muscles, remember that some are deep and others superficial. Is the transversus abdominis a superficial or deep muscle? How are its fibers directed?
The transversus abdominis is a deep muscle located underneath the internal oblique muscle in the abdominal wall. Its fibers are directed horizontally, running transversely across the abdomen from the sides towards the midline. This muscle is important for providing stability and support to the abdominal wall and spine.
