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. Deeper muscles, such as the multifidus and rotatores, segmentally stabilize the vertebrae and facilitate fine motor control of movement.
Posterior Thoracic Cavity Organ Arrangement and Anatomical Details
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. 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 pancreas, though primarily an abdominal organ, has a tail that extends toward the spleen, lying transversely across the posterior abdominal wall at the level of the first and second lumbar vertebrae. The erector spinae, the most superficial of these, run longitudinally along the spine and are responsible for extension and lateral flexion.
Posterior Thoracic Cavity Organ Arrangement and Anatomy
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. The Spinal Cord and Nervous System Highway Enclosed within the vertebral foramen runs the spinal cord, the central conduit for nerve signals between the brain and the periphery.
