vertebral arch of second thoracic vertebra
A neural arch forming the posterior bony ring of the second thoracic vertebra, composed of paired pedicles projecting posterolaterally from the vertebral body and paired laminae uniting at the spinous process. The arch bears the articular processes and transverse processes with costal facets, and gives attachment to the ligamenta flava, interspinous ligaments, and deep back musculature.
