Final answer:
The spine, also known as the vertebral column, is an important structure that supports and protects the spinal cord. Disorders associated with the curvature of the spine include kyphosis, lordosis, and scoliosis.
Step-by-step explanation:
The spine, also known as the vertebral column, is an important structure in the human body. It surrounds and protects the spinal cord, supports the head, and acts as an attachment point for ribs and muscles of the back and neck. Disorders associated with the curvature of the spine include kyphosis, lordosis, and scoliosis.
Kyphosis is an excessive posterior curvature of the thoracic region, which can cause a hunchback and thoracic compression. Lordosis is an excessive anterior curvature of the lumbar region, which can lead to a swayback appearance. Scoliosis is an abnormal lateral curvature accompanied by twisting of the vertebral column.
