Review Time Mari! Q. What does our back bone do for us? Who are we going to pick today… Very good Mari. Our backbone gives us both support and protection (spinal cord).

Question #2 Q. Where do we find cartilage in our bodies? Brian, are you paying attention back there? You’re up. I knew you would know the answer. Yes, cartilage can be found at joints, in between the vertebrae, and in our ears and noses. Excellent!!
