I WONDER - How Does The Spine Move?

The video tutorial explains the anatomy and function of the vertebral discs and facet joints in the spine. It describes how the rubbery discs between vertebrae act as cushions, allowing the spine to bend and twist while absorbing shock. The structure of these discs includes a tough outer layer and a jelly-like center. Additionally, the video covers how facet joints connect vertebrae, contributing to the spine's flexibility and movement.

What is the primary function of the soft rubbery discs located between each vertebra?

• To provide nutrients to the spine

• To act as a cushion and assist in movement

• To connect the vertebrae to muscles

• To store calcium for bone strength

What is the structure of the discs that allows them to absorb shock?

• A spongy outer layer with a solid core

• A fibrous outer layer with a hollow center

• A tough outer layer with a jelly-like center

• A hard outer shell with a liquid center

How do the discs prevent the vertebrae from rubbing against each other?

• By being flexible and shock-absorbent

• By being rigid and immovable

• By being thin and slippery

• By being thick and dense

What role do facet joints play in the spine?

• They provide blood supply to the vertebrae

• They connect vertebrae to muscles

• They store energy for movement

• They link each vertebra to its neighbor, enhancing flexibility

Which of the following best describes the function of facet joints?

• They allow for increased flexibility and movement

• They protect the spinal cord

• They store minerals for bone health

• They act as shock absorbers
