Which vertebral feature is described as the anticlinical (anticlinal) vertebra in the provided material?

• A. T11 (anticlinal)
• B. T12 (anticlinal)
• C. T10 (anticlinal)
• D. T13 (anticlinal)

Answer: (A)

The anticlinical (anticlinal) vertebra is the vertebra in the thoracic series where the dorsal spinous process is longest and represents the turning point of the spine’s orientation along the chest. In the material given, that peak occurs at the eleventh thoracic vertebra, so it is identified as the anticlinal vertebra. This vertebra often serves as a handy palpation landmark, marking the transition from the cranial to the caudal thoracic region. The other thoracic vertebrae listed do not show that same peak or landmark status in this context, so they aren’t described as the anticlinal vertebra here.
