Medical Terminology Simplified

Joints

10–51 To allow for body movements, bones must have points where they meet

(articulate). These articulating points form joints that have various degrees of

mobility. Some are freely movable (diarthroses); others are only slightly movable

(amphiarthroses), and the remaining are totally immovable (synarthroses). All three

types are necessary for smooth, coordinated body movements.

performed to repair and remove joint tissue, especially of the knee, ankle, and
