Tendon Tendons are similar to ligaments; both are made of collagen. Ligaments join one bone to another bone, while tendons connect muscle to bone.
Ancient Rome The civilization began as an Italic settlement in the Italian peninsula, dating from the 8th century BC, that grew into the city of Rome and which subsequently gave its name to the empire over which it ruled and to the widespread civilisation the empire developed. The Roman empire expanded to become one of the largest empires in the ancient world, though still ruled from the city, with an estimated 50 to 90 million inhabitants (roughly 20% of the world's population[3]) and covering 5.0 million square kilometres at its height in AD 117.[4]
