Ligaments are formed of  strong but elastic tissue. Bundles of yellow fibrous connective tissue form ligaments. These attach bones to each other at the joints. Ligaments connects one bone with the other.These form protective tissue elastic coverings on blood vessles and bronchioles. 
It has yellow fibres formed of protein elastein. Due to the presense of a network of elastic yellow fibres in the matrix, this tissue fibres are highly elastic.
These fibres are small and are found scattered in the matrix.
The main difference between a ligament and a tendon is that, ligament joins bone to bone while the tendons joines muscle to bone.

A ligament is a fibrous connective tissue which is composed of yellow fibrous tissue having great strength but limited flexibility.Its main function is that it connects one bone to another bone.When they connect 2 bones , they form a joint.
Ligament most commonly refers to a band of dense regular connective tissue bundles made of collagenous fibers, with bundles protected by dense irregular connective tissue sheaths.
