Final answer:
False. The spaces between the spinal discs do not widen, but they become thinner with age due to decreasing water content in the nucleus pulposus.
Step-by-step explanation:
The spaces between the spinal discs do not widen, but they actually become thinner with increasing age. Each intervertebral disc consists of two parts, the anulus fibrosus and the nucleus pulposus. The anulus fibrosus is the tough outer layer, while the nucleus pulposus is softer and gel-like. As people age, the water content in the nucleus pulposus decreases, causing the disc to become thinner and reducing flexibility and range of motion.
