WebThis leaves a structure consisting of two cartilaginous epiphyses at the ends of a hollow bony shaft. Growth from this point on is accomplished in two ways. Radial growth occurs by deposition of new bone on the periosteal surface and roughly equivalent resorption at the endosteal surface. WebThere are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”). These surfaces tend to conform to one another, such as one being rounded and the other cupped, to facilitate the function of the articulation. greenary backdrop
