Briefly describe the structure and function of tendons and ligaments.

Tendons and ligaments are both types of dense regular connective tissue, meaning their collagen fibers are arranged in parallel bundles, providing great strength in one direction. 
1. Tendons: Connect muscles to bones. They are tough, inelastic cords that transmit the force generated by muscle contraction to the bones, causing movement. 
2. Ligaments: Connect bones to other bones at joints. They are elastic, allowing for some stretch, and serve to stabilize joints and prevent excessive movement.
