What is a tendon primarily defined as?

A tendon is primarily defined as a cord of fibrous tissue that attaches muscle to bone. This definition captures the primary function of tendons, which is to transmit the force generated by muscles to the skeletal system, enabling movement. Tendons are made up of dense connective tissue, which gives them the strength and resilience needed to withstand the stresses that occur during muscle contraction. This connection allows for both stability and mobility in the joints, playing a crucial role in the musculoskeletal system.

While other options mention different connective structures or functions, they do not accurately describe what a tendon is or its primary role in the body. Options that refer to connective muscle to muscle or describe types of muscle tissue or joint cushioning miss the fundamental and specific definition of tendons as attachments between muscles and bones.
