Axial

The axial/appendicular skeleton consists of bones that surround the body's center of gravity.

This type of cartilage has great tensile strength and is found in the knee joint and intervertebral discs. A. Elastic B. Fibrocartilage C. Hyaline

False

True or False: The first seven pairs of the ribs are called flatting ribs because they only have indirect cartilage attachments to the sternum.
