Experiment 1 Classification of Bones Bones are primarily classified by two factors shape and location In this exercise you will use the model skeleton and determine the classification of the specified bones Materials Skeleton Model Procedure 1 Begin by looking over the model skeleton You will be classifying any 10 bones on the skeleton and describing them in Table 6 2 Use Table 5 Introduction to classify the shape of each of the 10 selected bones Record your findings in Table 6 3 Next classify each bone based on its location Record your findings in Table 6 Table 6 Classification of Numbered Bones Bone Name Classification by Shape Classification by Location Tibia Long bone Lower Leg Fibula Long bone Lower Leg Radius Long bone Lower Arm Ulna Long bone Lower Arm Femur Long bone Thigh Bone Clavicle Long bone Thoracic Region Sternum Flat Bone Thoracic Region Scapula Flat Bone Back Carpal Short Bone Wrist Tarsal Short Bone Ankle 2013 eScience Labs LLC All Rights Reserved Post Lab Questions 1 Why is it important to classify bones The classification of bones by shape can give more information about what is inside the bones and what they are made up of The long bones have a more complex interior and make bone marrow The classification by location is helpful and important because it tells where the bones are located in the body and how they affect the structure of the body 2 Aside from length what are some other common characteristics of a long bone Are long bones typically associated with the axial or appendicular skeleton Long bones are more associated with the appendicular skeleton They have a more complex interior than short irregular and flat bones They have a medullary cavity diaphysis and perform hematopoiesis 3 Compare flat bones and long bones How are they different How are they the same Flat bones are thin for the most part and thin throughout the bone Long bones are thick and long and have expanded ends They both have compact bone and an inner layer of spongy bone that is filled by trabeculae 2013 eScience Labs LLC All Rights Reserved
