Question

Which is a secondary curvature of the vertebral column that develops as a child begins to stand and walk?

a) Cervical curvature
b) Lumbar curvature
c) Thoracic curvature
d) Sacral curvature

Answer 1

Option b)lumbar curvature is the secondary curvature that develops in the vertebral column as a child begins to stand and walk.

Step-by-step explanation:

The secondary curvature of the vertebral column that develops as a child begins to stand and walk is the b) lumbar curvature.

This curvature is concave posteriorly, which is the opposite direction to the original fetal curvature. As a child transitions from sitting to standing and finally to walking, the lumbar curve strengthens to support the body's weight and maintain balance. This is in contrast to the thoracic and sacrococcygeal curves, which are considered primary curves because they are retained from the original fetal curvature.
