vertebral arch of tenth thoracic vertebra
A neural arch forming the posterior bony ring of the tenth thoracic vertebra, consisting of pedicles and laminae enclosing the vertebral foramen at the lower thoracic level. T10 is transitional; its arch bears transverse processes that may have a small costal facet for rib 10 and articular processes that begin to reflect the approaching thoracolumbar morphology.
