On the laboratory bench right in front of you, there is a bone. You can tell that it has an articular surface that is smooth and just slightly concave. This skeletal feature would be referred to as a Facet.
<h3>What is the composition of human bone?</h3>
A transcription factor collagen forms the structure of bones, and calcium phosphate, a mineral, gives the framework strength and hardness. When other body parts require calcium, bones release some of the calcium they have stored into the blood.
<h3>Why are bones so durable?</h3>
A living, developing tissue is bone. Collagen, a polypeptide that provides a soft structure, and calcium, a mineral that gives strength and hardness, make up the majority of its composition. Together, these factors give bone the strength and flexibility it needs to withstand stress.
