Small bones found in tendons are termed what?

• A. Sesamoid
• B. Cartilaginous
• C. Synovial
• D. Ossicles

Answer: (A)

Small bones found in tendons are referred to as sesamoid bones. These bones develop within the tendons and serve to protect them and improve the mechanical function and leverage of the muscles associated with those tendons. A classic example of sesamoid bones is the patella (kneecap), which is found in the tendon of the quadriceps muscle. The presence of sesamoid bones can vary among individuals and different anatomical locations. Their primary role is to provide a smooth surface for tendons to glide over, reduce friction, and prevent wear and tear. Their unique positioning also alters the angle of muscle tendons, enhancing the strength of muscle contractions. The other options—cartilaginous, synovial, and ossicles—refer to different structures in the body: cartilaginous relates to cartilage, synovial pertains to the type of joint that allows for movement, and ossicles are small bones in the middle ear. They do not describe small bones specifically located within tendons. This makes sesamoid the correct term for the small bones in question.
