An exaggerated curvature of the lumbar spine is known as __ Lordosis Osteosis Scoliosis Kyphosis

## Step 1<br />The question is asking for the term that describes an exaggerated curvature of the lumbar spine. The lumbar spine refers to the lower part of the spine.<br /><br />## Step 2<br />Let's go through each of the options:<br /><br />- Lordosis: This term refers to an inward curvature of the lower back or lumbar region. This matches the description given in the question.<br /><br />- Osteosis: This term refers to the formation of new bone, which is not related to the curvature of the spine.<br /><br />- Scoliosis: This term refers to a sideways curvature of the spine that usually occurs during growth spurts before puberty. This does not match the description given in the question.<br /><br />- Kyphosis: This term refers to an excessive outward curve of the spine, resulting in an abnormal rounding of the upper back. This is not the same as an exaggerated curvature of the lumbar spine.
