T1 vertebra
T1 is an atypical thoracic vertebra. In contrast to typical thoracic vertebrae, it contains a complete facet for the 1st rib and a demifacet for the 2nd rib. It contains lips on the upper surface of the body. T1 also has a spinous process more horizontal than other thoracic vertebrae.
Article
T11 vertebra
T11 is an atypical thoracic vertebra. In contrast to typical thoracic vertebrae, it contains a single costal facet that articulates with the atypical eleventh rib. There are no facets on the transverse processes.
Article
T12 vertebra
T12 is an atypical thoracic vertebra. In contrast to typical thoracic vertebrae, it contains a single costal facet with no facets on transverse processes.
Article
Atypical thoracic vertebrae
T1 and T9 - T12 are considered atypical thoracic vertebrae.
T1 bears some resemblance to low cervical vertebrae
T9 has no inferior demifacet
T10 often, but not always, shares features with T11 and T12.
For a basic anatomic description of the structure a generic vertebra, see vertebrae.

Thoracic spine
The thoracic spine (often shortened to T-spine) forms the middle part of the vertebral column. It extends from below C7 of the cervical spine to above L1 of the lumbar spine. There are 12 thoracic vertebra, termed T1-T12.
The thoracic spine is unique due to its articulation with ribs via costal...
