Science quiz | About the spine

question:

1. What are the names of various invertebrate marine animals characterized by hard, spiny coverings or skin?

2. Name the part of the spine that is the fibrocartilage that joins two adjacent vertebrae. In space, this area is depressurized, allowing astronauts to grow a little taller, but when they return to Earth, they lose that height.

3. Cerebrospinal fluid (CSF) is a fluid produced in the ventricles of the brain that acts as a shock absorber that surrounds and protects the organs and spinal cord. Name the condition caused by excessive accumulation of CSF within the ventricles.

4. Name the condition caused by the vestigial organs of the spine and commonly attributed to the “beach chair” posture, i.e., sitting with the pelvis tilted dorsally in quadriplegic individuals.
