Lab 6 The Skeletal System BIO201L Student Name: Access Code (located on the lid of your lab kit): AC-DWWOAS Pre-Lab Questions: ” 1. List the functions of the skeletal system. ” Suport the body so the body can stand up, also is very important with the productions of red blood cells. ” 2. What material contributes the greatest to the compressive strength of bone? ” calcium ” 3. Briefly describe the process of bone remodeling. ” Osteoclasts first break down mineralized bone, and then osteoblasts form bone matrix, which later undergoes mineralization. Experiment 1: Classification of Bones Table 6: Classification of Bones Bone Name Classification by Shape Classification by Location Humerus Long bone Apperdicular Pelvis Flat bone axial Ribs Flat bone Axial Sternum Flat bone Axial Ulna Long Appendicular Tarpals Short Appendicular Tibia Long Appendicular Femur Long Appendicular Radius Long Appendicular Temporal Flat axial Post-Lab Questions ” 1. Why is it important to classify bones? ” It is imporant because it plays a crucial role when it comes to treatment, because it depends on where the bones is located for type of treatment. ” 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 are usually appendicualr. Thid consist oft he femur, tibia, phalanges, metatarslas. ” 3. Compare flat bones and long bones. How are they different? How are they the same? ”

Lab 6 The Skeletal System BIO201L Flat bones, like the skull and sternum, are thin and protective, whereas long bones, such as the femur and humerus, are crucial for mobility and support oft he body and organs. Experiment 2: Digital Slide Image Examination—Bone Post-Lab Questions ” 1. Label the arrows in the following digital slide images: ” ” Cortical Bone: ” A- Haversian System B- Interstitial Lamella C- concentric Lamellae D- Harversian canals ” Trabecular Bone: ” A- Trabeculae B- Marrow Cavity

Lab 6 The Skeletal System BIO201L ” 2. Compare and contrast cortical and trabecular bone. ” Cortical bone is very dense and forms the outer layers of bones, cortical bones provide strength and stability. Trabecular bone, on the other hand, is found in the interior, this bone has a higher surface area than cortical bones. ” 3. What is the purpose of cortical bone? What is the purpose of trabecular bone? ” They are compact bones, and are used as the protective layer oft he bones, this bones are essential in th eprotection of vital organs. ” 4. What are trabeculae? What is their function? ” Trabeculae are lattice-like structures within trabecular and/pr spongy bone that provide support, absorb shock, but also is where red bone marrow is produced. ” 5. What are haversian systems? What is their function? ” They are known as osteons and found wihtin the cortical bones. This bones are essential in the primary function of nutrien, oxygen and waste product transport from bone to cells.
