Achondroplasia is a genetic condition that causes a bone growth inhibitor, known as fibroblast growth factor receptor 3, to be overly aggressive and this restricts bone growth. The second most common cause is a deficiency in growth hormone (somatotropin).

Cementite is iron carbide with the formula Fe 3 C, and an orthorhombic crystal structure. It is a hard, brittle material, essentially a ceramic in its pure form.It forms directly from the melt in the case of white cast iron.ementite contains 6.67% Carbon by weight; thus above that carbon content in the Fe-C phase system, the alloy is no longer steel or cast iron, as all of the available iron is contained in cementite. Cementite mixes with ferrite, the other product of austenite, to form lamellar structures called pearlite and bainite.
