Question

A normal human spine contains only one slight curve inward at the waist.​

Quizplus · Accepted Answer

A normal human spine actually contains four slight inward curves: one at the neck (cervical spine), one at the mid-back (thoracic spine), one at the lower back (lumbar spine), and one at the pelvis (sacral spine). These curves help the spine to evenly distribute weight and absorb shock.
