Thoracic Spine Nerves ((top)) Site

The thoracic spinal nerves comprise the twelve pairs of spinal nerves emanating from the thoracic vertebrae. While often overshadowed by the cervical and lumbar plexuses in clinical discourse, the thoracic nerves are critical for autonomic regulation, trunk stability, and cutaneous innervation. This paper provides a detailed examination of the thoracic nerve anatomy, their unique exit pathways via intervertebral foramina, the formation of the thoracic plexus, and the clinical syndromes associated with thoracic nerve pathology, including intercostal neuralgia and thoracic outlet syndrome.

Upon exiting the intervertebral foramen, each thoracic nerve divides into four primary rami (branches): thoracic spine nerves
