Does the vagus nerve travel through or near the psoas muscle?

The vagus nerve does not travel through the psoas muscle, but it is anatomically close to it. The vagus nerve primarily runs in the neck and thorax, branching off from the brainstem and descending through the neck and into the abdomen. While the psoas muscle is located in the lower back and pelvis, the vagus nerve's pathways do not directly interact with it. However, the vagus nerve does innervate organs that are in proximity to the psoas, such as the stomach and intestines.
