This laboratory is concerned with the identification of the histological features and distinguishing characteristics of developing and adult bone


Bone is multifunctional in that it (1) supports the body and its fleshy structures, (2) protects vital structures in the cranial and thoracic cavities, in addition to protecting the hemopoietic cells within the bone marrow. (3) is an reservoir for calcium, magnesium, phosphate and other ions that can be released or stored in a controlled fashion to maintain constant concentrations in body fluids, (4) is a lever system that multiplies the forces generated during skeletal muscle contraction and transforms them into bodily movements.

Keep in mind that bone is a connective tissue consisting of cells (osteoblasts, osteocytes, osteoclasts), fibers (collagen), and ground substance. The organic "matrix" of fibers and ground substance becomes embedded with calcium hydroxyapatite crystals and other ions.
