Lab 6 The Skeletal System BIO201LStudent Name: Nicholaus McDevit
Access Code (located on the lid of your lab kit): AC-3VSAZEM
Pre-Lab Questions:
”1. List the functions of the skeletal system.”
Support, Movement, Protection, Storage of bone marrow, Red marrow production.
”2. What material contributes the greatest to the compressive strength of bone? ”
Calcium carbonate and calcium phosphate
”3. Briefly describe the process of bone remodeling. ”
The bones are able to be reshape from adapting to the physical needs.
Experiment 1: Classification of Bones
Table 6: Classification of Bones
Bone Name Classification by Shape Classification by Location
Carpals Short Appendicular
Radius Long Appendicular
Ulna Long Appendicular
tibia Long Appendicular
Tarsals Short Appendicular
Sternum Flat Axial
Femur Long Appendicular
Vertebrae Irregular Axial
Frontal Flat Axial
Temporal Flat Axial
Post-Lab Questions
”1. Why is it important to classify bones? ”
Bones have different appearances and functions. Classifying them makes them easier to identify
and treat conditions.
”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? ”
Longs bones typically have cartilage on their ends to prevent friction at joints, they are
associated with appendicular skeleton.
”3. Compare flat bones and long bones. How are they different? How are they the same? ”
,Lab 6 The Skeletal System BIO201L
Flat bones have a flat surface while long bones are long and shaped like a column. They both are
sites for red bone marrow production.
Experiment 2: Digital Slide Image Examination—Bone
Post-Lab Questions
”1. Label the arrows in the following digital slide images: ”
”Cortical Bone: ”
A- Interstitial Lamellae
B- Haversian System
C- Concentric Lamellae
D- Haversian Canals
”Trabecular Bone: ”
A- Trabeculae
B- Marrow Cavity
, Lab 6 The Skeletal System BIO201L
”2. Compare and contrast cortical and trabecular bone. ”
Both bones are produced by the same cell types. Cortical bone make up most of long bones and
have a thick structure. Trabecular bone appear sponge like but are not soft. They are found in
the wrists and ankles, as well as at the end of long bones.
”3. What is the purpose of cortical bone? What is the purpose of trabecular bone? ”
The cortical bone provides support and framework. They also allow nerves and blood vessels to
pass though bone tissue. Trabecular bone holds blood vessels in nerves in the tiny spongy holes.
”4. What are trabeculae? What is their function? ”
Trabeculae are small cavities where blood cells are produced.
”5. What are haversian systems? What is their function? ”
The harversian systems consist of compact bone tissue that holds the blood cell supply for
bones.
