Experiment 2 Digital Slide Image Examination Bone In this experiment you will explore the components within cortical and trabecular bone Materials Cortical Compact Bone Digital Slide Image Trabecular Spongy Bone Digital Slide Image Post Lab Questions 1 Label the arrows in the following digital slide images A Interstitial lamellae B Haversian system C Concentric lamellae D Haversian canals 2013 eScience Labs LLC All Rights Reserved A Trabeculae B Marrow Cavity 2 Compare and contrast cortical and trabecular bone The cortical bone is in the shaft of long and short bones and on the outside of irregular bones It is for support and protection They are 80 90 calcified and they have a very high resistance to fractures The trabecular bone is in the epiphysis of long bones and in the center of flat and irregular bones It is for metabolic functions such as remodeling They are 15 25 calcified and they have a very low resistance to fractures 3 What is the purpose of cortical bone What is the purpose of trabecular bone The purpose of the cortical bone is to be strong and protect the trabecular bone The trabecular bone is responsible for blood cell production and carries out regenerative functions 4 What are trabeculae What is their function Trabeculae are the primary structures inside a trabecular bone They work together to carry out the functions of the trabecular bone They bear weight and help bones resist bending and twisting 5 What are haversian systems What is their function A haversian system is a series of lamellae that is found in the compact bone of humans Each bone has many haversian systems that line up by each other and create a dense structure They are also known as osteons It provides the support and is the basic unit for the compact bone 2013 eScience Labs LLC All Rights Reserved
