Vertebra T7

The thoracic vertebra T7 (7th thoracic vertebra) is part of the middle thoracic spine and has several distinct anatomical features.

• The vertebral body of T7 is heart-shaped and larger than those of the cervical vertebrae but smaller than the lumbar vertebrae.

• The vertebral foramen is circular and smaller compared to the cervical vertebrae.

• The transverse processes of T7 are long and robust, projecting laterally and slightly posteriorly. Each transverse process has a costal facet for articulation with the tubercle of the corresponding rib.

• The spinous process of T7 is long, slender, and directed downward, overlapping the vertebra below.

• The superior and inferior articular facets of T7 are oriented in a coronal plane, allowing for some rotation but limiting flexion and extension. The superior articular facets face posteriorly and slightly laterally, while the inferior articular facets face anteriorly and slightly medially.

• The T7 vertebra also has a pair of demifacets on the posterolateral aspects of its body for articulation with the heads of the seventh and eighth ribs.

• The pedicles are short and stout, projecting directly backward from the vertebral body, and the laminae are broad and thick, forming the posterior part of the vertebral arch.
