Final answer:
A lateral curvature of the spine is known as scoliosis, a condition characterized by abnormal lateral bending and possibly a twisting of the vertebral column.
Step-by-step explanation:
A lateral curvature of the spine is known as scoliosis. This condition is characterized by an abnormal lateral bending of the vertebral column, often accompanied by a twisting of the vertebral column. It contrasts with kyphosis, which is an excessive curvature of the upper thoracic vertebral column, and lordosis, an excessive curvature in the lumbar region.
Disorders of the vertebral column such as scoliosis, kyphosis, and lordosis can be due to developmental anomalies, pathological changes, or obesity. These curvatures of the spine can appear during preteen years or become more pronounced with age and are often treatable by orthopedic specialists.
