T8 (8th Thoracic Vertebra)

The T8 vertebra is toward the lower (caudal) end of the twelve (12) thoracic vertebrae within the central, torso section of the spine. Like the other similar T2-9 thoracic vertebrae, the T8 consists of a larger, heart-shaped centrum (ventral body) and an increasingly large vertebral arch. The vertebral arch includes pedicles that are larger than those above them, laminae that overlap with the T9 vertebra, and significant transverse bodies. These transverse bodies have facets on their...

    Full T8 (8th Thoracic Vertebra) Description

    [Continued from above] . . . exterior faces that, together with demi-facets on the upper and lower sections of the centrum's exterior, provide an articular space for the tubercles of the ribs connecting to either side of the T8 vertebra. Ventral to the vertebral arch, the long spinous process projects downward and overlaps with that of the T9 vertebra below it. The circular vertebral foramen encloses and protects the nerves of the spinal cord.
