DescriptionUnreviewed
The first thoracic vertebra has, on either side of the body, an entire articular facet for the head of the first rib, and a demi-facet for the upper half of the head of the second rib.
The body is like that of a cervical vertebra, being broad, concave, and lipped on either side.
The superior articular surfaces are directed upward and backward; the spinous process is thick, long, and almost horizontal.
The transverse processes are long, and the upper vertebral notches are deeper than those of the other thoracic vertebrae.
The thoracic spinal nerve 1 (T1) passes out underneath it.
