How do tendons connect muscles to bones?
Quick Answer
Tendons are strong cords of connective tissue that attach muscle to bone and transmit pulling force. They are rich in collagen, which gives them high tensile strength.
The Full Story
When a muscle contracts, it shortens and pulls on a tendon, which then pulls the bone it is attached to. Tendons are made mostly of collagen fibers arranged to resist tension, allowing them to handle large forces without snapping. Examples include the Achilles tendon in the ankle and the tendons in the hand that control finger motion. Because tendons have relatively low blood supply, they can heal slowly after injury. Their job is essential for converting muscle contraction into movement.
