Which term describes an increased curvature of the lumbar spine?

The term that describes an increased curvature of the lumbar spine is lordosis. This condition is characterized by an excessive inward curve of the lumbar region, which can lead to a protruding abdomen and an over-arched lower back. In a healthy spine, there are natural curves that help distribute weight and absorb shock; however, when this curvature is exaggerated, it can cause discomfort and may impact mobility.

Kyphosis, on the other hand, refers to an increased curvature of the thoracic spine, leading to a hunchback appearance, which is different from the lumbar region. Scoliosis describes a lateral curvature of the spine, resulting in an "S" or "C" shaped appearance, rather than an increase in the lumbar curvature. Vertebrae are the individual bones that make up the spine and do not describe a curvature condition. Understanding these terms and their specific meanings is important for recognizing different spinal-related conditions.
