Within this bony cage, the lungs occupy the pleural cavities on either side of the mediastinum, extending from the apex near the collarbone down to the diaphragm. The esophagus and major vessels like the aorta run vertically behind the heart, positioned precisely behind the sternum and in the midline of the thoracic spine.
Deep Structures of the Back Layers and Organ Location
The precise location of these nerve roots is critical for procedures like lumbar punctures, which must be performed below the L2 level to avoid direct puncture of the cord. The location of the kidneys can often be approximated by drawing horizontal lines at the levels of the 12th rib; the upper pole of the right kidney typically sits at the T12 vertebra, while the left kidney is slightly higher due to the presence of the liver.
Running parallel to these processes is the sacrospinalis muscle group, which gives the back its characteristic contour. The Posterior Abdominal Wall In the lumbar region, the location of organs shifts to the retroperitoneal space, which lies behind the peritoneal lining of the abdominal cavity.
Deep Structures and Layers of the Back Surface Anatomy
The erector spinae, the most superficial of these, run longitudinally along the spine and are responsible for extension and lateral flexion. Positioned to the left of the midline, the left kidney is nestled against the psoas major muscle, whereas the right kidney is slightly lower due to the displacement by the liver.
