Which prefix relates to the concept of stretching or tendons?

The prefix that relates to the concept of stretching or tendons is "ten/o." This prefix is derived from the Greek word "tenon," which means "tendon." In medical terminology, it is commonly used in terms relating to tendons throughout the body, indicating conditions, procedures, or anatomical references concerning these fibrous tissues that connect muscles to bones.

For example, in the term "tendinitis," which involves inflammation of a tendon, the "ten/o" prefix directly reflects the involvement of tendon structures. Understanding this prefix is essential for interpreting various medical terms associated with tendon injuries or disorders.

The other options relate to different concepts: "synov/o" pertains to synovial fluid or membranes, "ankyl/o" refers to stiffness or fusion, commonly used in conditions like ankylosing spondylitis, and "-ptosis" indicates a drooping or prolapse of an organ or structure. These do not connect directly to tendons or their functions, differentiating them from "ten/o."
