The external oblique muscle is situated _____ to the transversus abdominus muscle.

The external oblique muscle is situated lateral to the transversus abdominus muscle. This anatomical relationship is essential to understand as it relates to the organization of the abdominal muscles. The external oblique is positioned on the outermost layer of muscle in the abdominal wall, providing support and contributing to the movement and stability of the trunk.

In the arrangement of the abdominal muscles, the external oblique is found peripherally, while the transversus abdominus lies deeper within the abdominal wall. This lateral positioning allows the external oblique to assist in various functions such as trunk rotation and lateral flexion, making it vital for movements that involve twisting or bending.

The significance of this orientation extends to clinical practices, where knowledge of muscle positioning aids in approaches to diagnostic imaging, surgical procedures, and rehabilitation strategies. Understanding these relationships helps in accurate sonographic assessments of the abdominal region.
