The study of bones is called Osteology.
A new born has about 300 bones in its body, many of which fuse later in life to form 206 bones in an adult.

The longest bone in the human body is the Femur or the thigh bone.
The smallest bone is located in the ear and known as the stapes.
Bones are attached to bones by tough, fibrous tissues known as ligaments
The flexible tissue in the interior of bones is known as the bone marrow. Red and white blood cells are produced in the bone marrow.
