Long bones are used primarily for movement rather than protection. A few examples of long bones are the humerus, tibia, and phalangeal bones.
The four principal types of bones are long, short, flat and irregular. Bones that are longer than they are wide are called long bones. They consist of a long shaft with two bulky ends or extremities. Osteoblasts are cells responsible for the secretion and deposition of bone morphogenetic proteins (BMPs) into the extracellular matrix during bone formation.
Appositional growth is the increase in the diameter of bones by the addition of bone tissue at the surface of bones. Bone remodeling involves the processes of bone deposition by osteoblasts and bone resorption by osteoclasts.
