Nerves Of The Thoracic Spine Jun 2026

Each thoracic spinal nerve is a mixed nerve, meaning it contains both sensory (afferent) and motor (efferent) fibers. Immediately after exiting the spinal column, the nerve divides into two main branches: the larger and the smaller dorsal ramus . This bifurcation allows for specialized innervation of different body regions. The dorsal rami are relatively simple: they curve around to the back of the trunk, supplying the deep intrinsic muscles of the back (which control posture and fine movements of the spine) and the skin overlying the spine itself. Injury or irritation of a dorsal ramus can lead to localized mid-back pain, muscle spasms, or a band of altered sensation along the spine.

The thoracic spine, also known as the dorsal spine, is a crucial part of the human vertebral column. It is situated between the cervical and lumbar spine and plays a vital role in supporting the upper body, facilitating breathing, and enabling a wide range of movements. The thoracic spine is comprised of 12 vertebrae (T1-T12) and is associated with a complex network of nerves that control various bodily functions. nerves of the thoracic spine
