What is referred to as exaggerated anterior-posterior curvature of the spinal column?

The condition characterized by exaggerated anterior-posterior curvature of the spinal column is kyphosis. This specifically refers to an abnormal outward curvature of the thoracic spine, which can lead to a hunchback appearance. In this condition, the spine curves excessively forward, which can affect posture and may result in discomfort or pain in some cases.

Lordosis, while also a spinal curvature issue, refers to an exaggerated inward curvature, typically seen in the lumbar region. Scoliosis involves a lateral curvature of the spine rather than a front-to-back curvature. Spondylosis is a general term for age-related wear and tear on the spine that can lead to degenerative changes, but it does not specifically refer to a curvature condition like kyphosis does. Thus, kyphosis specifically encompasses the exaggerated anterior-posterior curvature described in the question.
