T5 (5th Thoracic Vertebra)

Last updated: Nov 15th, 2024

The T5 vertebra is the fifth of the twelve (12) thoracic vertebrae from the top of this central section of the spinal column. It has a large centrum in a heart-like shape with superior and inferior costal demi-facets above and below on the exterior that - with like costal facets on the transverse processes - make an articular space for the heads of the ribs that connect with the T5 vertebra. The ventral body (centrum) is flat above and below. On the posterior side of the vertebral arch, each of the downward projecting spinous processes from T5 to T8 overlaps with the spinous process below it. A circular vertebral foramen encloses the spinal cord from within the protection of the vertebral arch, and two increasingly large pedicles provide support to the spine as a whole. The T5 vertebra as a whole is larger than the thoracic vertebrae above it.
