Lab Report Format Expectations
Utilize college level grammar and professional formatting when completing this
worksheet. Submissions without proper formatting, all required photos or sufficient
responses will be rejected. Pre-lab Questions
1. List the functions of the skeletal system.
The skeletal system gives the body structure, protects vital organs, stores minerals,
helps with movement, and makes blood cells in the bone marrow.
2. What material contributes the greatest to the compressive strength of bone?
Calcium phosphate is the main material that gives bones their strength under pressure.
3. Briefly describe the process of bone remodeling.
Bone remodeling is when old bone tissue is broken down by cells called osteoclasts and
replaced by new tissue through osteoblasts, helping bones stay healthy and strong.
EXPERIMENT 1: CLASSIFICATION OF BONES
Introduction Questions
1. Why is it important to classify bones?
Classifying bones helps us understand their shape and where they are in the body,
making it easier to study their roles in movement and support.
Data and Observations
Insert your observations for this experiment in the table below.
Table 6: Classification of Bones
Bone Name Classification by Shape Classification by Location
Femur Long Appendicular
Radius Long Appendicular
Tibia Long Appendicular
Ulna Long Appendicular
Tarpals Short Appendicular
Carpals Short Appendicular
, Vertebrae Irregular Axial
Frontal Flat Axial
Temporal Flat Axial
Sternum Flat Axial
Results and Discussion

1. 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 have a shaft, two ends, and contain marrow. They are mostly part of the
appendicular skeleton, which helps the body move.
2. Compare flat bones and long bones. How are they different? How are they the same?
Flat bones are thin and protect organs, while long bones are longer than they are wide
and help with movement. Both types contain bone marrow and provide support.
EXPERIMENT 2: DIGITAL SLIDE EXAMINATION - BONES
Introduction Questions
1. What is the purpose of cortical bone? What is the purpose of trabecular bone?
Cortical bone is dense and strong, providing support and protection. Trabecular bone is
spongy and helps with shock absorption and bone flexibility.
2. What are trabeculae? What is their function?
Trabeculae are small, beam-like structures in spongy bone that help support and distribute
force.
3. What are haversian systems? What is their function?
Haversian systems, or osteons, are cylindrical structures in compact bone that contain
blood vessels and nerves to nourish bone cells.
