Root words – provide the fundamental meaning of a term. Combinations of rootwords, prefixes and suffixes form medical and scientific terms. A vowel, called a combining vowel, often is added when two root words are combined or a suffix is added to a root word; the combining vowel is usually an o or an i.

Fibrocartilage – Cartilage that consists of a dense matrix of white collagenous fibers.
Joint – any one of the articulations between bones
Articulation – movements of joints
Bursae – a fibrous sac between certain tendons and the bones beneath them. The bursae acts as a small cushion that allows the tendons to move over the bone as it contracts and releases
