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 Thoracic Cavity and Ribcage Protection Superiorly, the back houses the thoracic cavity, protected by the ribcage which attaches posteriorly to the thoracic vertebrae.
Spinal Cord Nerve Exit Foramina Pathway and Vertebral Column Anatomy
The cord does not extend the entire length of the vertebral column; in adults, it typically ends at the L1 or L2 vertebra, forming the conus medullaris. Surface Anatomy and the Vertebral Column The thoracic and lumbar vertebrae create the bony framework of the back, with the spinous processes forming the visible and palpable midline ridge.
Running parallel to these processes is the sacrospinalis muscle group, which gives the back its characteristic contour. The heart, although primarily located in the anterior mediastinum, sits between the lungs with its apex pointing leftward; its position is stabilized by the surrounding connective tissue attached to the sternum and vertebrae.
Spinal Cord Nerve Exit Foramina Pathway and Anatomy
Below this point, the cauda equina—a bundle of nerve roots resembling a horse's tail—descends through the lumbar cistern to exit at their respective intervertebral foramina. This guide provides a detailed anatomical overview of the posterior torso, moving from the surface anatomy to the deep structures protected by the vertebral column.
