What is the root word for synovial?

The root word for synovial is synov/o. This root word specifically pertains to synovial fluid and the synovial membrane, which are crucial components of synovial joints in the body. Synovial joints are characterized by the presence of a fluid-filled space that allows for smooth movement between the articulating bones, and the term "synovial" directly relates to this fluid and its surrounding structures.

While synovi/o may seem similar and is occasionally used as a variant in some medical contexts, synov/o is the more widely accepted root in medical terminology. The other options provided, ten/o and tendon/o, relate to tendons and are not relevant to the concept of synovial joints. Understanding these root words is essential for grasping how they connect to the anatomical structures and functions within the body.
