Which of the following are associated with primary spine curvatures?Group of answer choicesconcave anteriorcervical curvelumbar curveconvex anteriorlordosis

Primary spine curvatures are the spinal curvatures that are present at birth, which include the thoracic and sacral curvatures. These curvatures are concave anteriorly.

1. Concave anterior: This is associated with primary spine curvatures. The thoracic and sacral curvatures of the spine are concave anteriorly.

2. Cervical curve: This is not associated with primary spine curvatures. The cervical curvature is a secondary curvature that develops after birth, specifically when a baby starts to hold up its head.

3. Lumbar curve: This is not associated with primary spine curvatures. The lumbar curvature, like the cervical curvature, is a secondary curvature that develops later, specifically when a baby starts to walk.

4. Convex anterior: This is not associated with primary spine curvatures. The primary curvatures (thoracic and sacral) are concave anteriorly, not convex.

5. Lordosis: This term refers to an exaggerated lumbar curvature. It's not directly associated with primary spine curvatures, but rather with a possible abnormality or exaggeration of the secondary lumbar curvature.
