Seventh Thoracic Vertebra T7, Lateral View

Description

Seen in lateral profile, the seventh thoracic vertebra (T7) is presented as a single mid-thoracic motion segment element with a relatively heart-shaped vertebral body anteriorly and the vertebral arch posteriorly. Pedicles project posterolaterally from the body and merge into the laminae, which meet to form the spinous process directed inferiorly, typical of the thoracic region. The superior and inferior articular processes define the zygapophyseal (facet) joints, while the transverse process extends laterally and carries a transverse costal facet for the tubercle of a rib; demifacets on the posterolateral vertebral body accommodate the head of the rib at the costovertebral joint. A true lateral view of T7 matters because it clarifies thoracic kyphosis and the relationship of the pedicles, facets, and spinous process that constrain flexion and extension compared with the lumbar spine. This is a key segment for correlating trauma patterns such as flexion-distraction injuries and for understanding why thoracic fractures can threaten the spinal canal even with modest displacement. Pedicle morphology is also central. Screw trajectory planning and safe decompression depend on it. Medical educators will find this image well suited for gross anatomy and musculoskeletal blocks when teaching vertebral regional differences, rib articulations, and the architecture of the vertebral arch. It also supports radiology and spine surgery materials that pair lateral radiographs or CT sagittal reconstructions with bony landmarks for level identification in the mid-thoracic spine.
