INTRODUCTION As the main constituent of the adult skeleton, bone tissue supports fleshy structures, protects vital organs such as those in the cranial and thoracic cavities, and harbors the bone marrow, where blood cells are formed.
This is a crucial step in tissue preparation, and its purpose is to prevent tissue autolysis and putrefaction. 13. The bone matrix has 2 major components.
