The fourth thoracic vertebra, together with the fifth, is at the same level as the sternal angle. The thoracic spinal nerve 4 (T4) passes inferior it. A thoracic spine X-ray of a 57-year-old male. Surface orientation of T3 and T7, at middle of spine of scapula and at inferior angle of the scapula, respectively.
The thoracic nerves are the twelve spinal nerves emerging from the thoracic vertebrae. Each thoracic nerve T1–T12 originates from below each corresponding thoracic vertebra . Branches also exit the spine and go directly to the paravertebral ganglia of the autonomic nervous system where they are involved in the functions of organs and glands ...
Enostosis is usually found in T1 to T7 for the thoracic spine and L2 to L3 in the lumbar spine. It consists of cortical bone merging with medullary bone with irregular margins. The shape of the lesion is round or oval with a thornlike margin, up to 2 cm in diameter. In both T1 and T2-weighted imaging, it shows low signal intensity.
A corpectomy or vertebrectomy is a surgical procedure that involves removing all or part of the vertebral body (Latin: corpus vertebrae, hence the name corpectomy), usually as a way to decompress the spinal cord and nerves. Corpectomy is often performed in association with some form of discectomy. [1]
The specific vertebrae classify spinal nerve roots they originate from. These are separated into three sections: cervical, thoracic, lumbar, and sacral. The cervical is separated into eight vertebrae named C1-C8. The thoracic segment consists of T1-T12; the lumbar is L1-L5; and sacral S1-S5. [5]
In the thoracic and lumbar spine, the facet joints are innervated by the medial branch nerves from the vertebral segment above the upper segment and the upper segment. For example, the facet joint between T1 and T2 is innervated by C8 and T1 medial branch nerves. Facet joint between L1 and L2; the T12 and L1 medial branch nerves.

The thoracic spinal nerve 1 (T1) is a spinal nerve of the thoracic segment. [ 1 ] It originates from the spinal column from below the thoracic vertebra 1 (T1).
