What is the primary function of a tendon?

The primary function of a tendon is to connect muscles to bones and enable movement. Tendons are tough, fibrous connective tissues that serve as the attachment points for muscles. When a muscle contracts, it pulls on the tendon, which in turn pulls on the bone to create movement at the joint. This connection is essential for virtually all physical activities, whether they involve fine motor skills or large, powerful movements.

In contrast to the other options, tendons do not provide blood supply to muscles, nor do they facilitate communication between muscles. Blood supply is primarily handled by blood vessels, while communication between muscles involves neural signals. While tendons do help support the overall structure of the musculoskeletal system by connecting muscles and bones, their main role is to transmit the force generated by muscle contractions to facilitate movement.
