The four layers going from the outer to the innermost bone are periosteum, compact bone, spongy bone and bone marrow. The periosteum has dense connective tissues concealing the bone’s surface. Next, there is the compact bone, which is durable to protect the spongy bone and bone marrow. The spongy bone contains trabeculae, which bone marrow fills up the open spaces in between. The bone marrow’s function is to produce red and white blood cells along with platelets. Moreover, bones have five different shapes that vary in every part of the human skeleton, which are, long short, flat, irregular and
