NAME 2 REGIONS OF THE VERTEBRAL COLUMN AND STATE THE NUMBER OF BONES FOUND IN EACH.

Cervical -7

Sacrum - 5

WHAT ARE INTERVERTEBRAL DISCS MADE OF AND WHAT IS THEIR FUNCTION?

Intervertebral discs are Cartilage found in between the bones of the vertebrae.

They act as shock absorbers, reduce friction and retains structural integrity.

  • Experiment : An experiment is designed to test a hypothesis.
  • Data : Consists of measurements, observations/information gathered during an experiment.
  • Replicate : A repeat of an experiment.
  • Control : A comparison used to provide a standard against which the actual experiment can be judged.
