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.
Supports and protects the body, enables movement, stores nutrients, and produces new
blood cells.
2. What material contributes the greatest to the compressive strength of bone?
Hydroxyapatite. It's a form of calcium phosphate that makes up about 60% of bone's
structure, contributing significantly to its strength and ability to withstand stress.
Additionally, hydroxyapatite promotes bone regeneration and repair by providing a
scaffold for new bone growth.
3. Briefly describe the process of bone remodeling.
During bone remodeling, the fracture site is filled with compact bone. Within the
compact bone, osteons from both sides travel across the fracture to connect the
fragmented bones together.

EXPERIMENT 1: CLASSIFICATION OF BONES
Introduction Questions
1. Why is it important to classify bones? Provide a few sentences in response to this
question, below.
By categorizing bones, we can compare them across species, identify commonalities and
differences, and trace evolutionary lineages. In medicine, accurate bone classification is
essential for diagnosing and treating injuries, as well as for conducting research on
musculoskeletal health.
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
Parietal flat axial
Humerus long appendicular
fibula Iong appendicular
tibia long appendicular
scapula flat appendicular
frontal flat axial
zygomatic irregular axial
clavicle long axial
ilium flat axial
tarsus short appendicular
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?
Shaft at two ends, cartilage on ends, associated with the appendicular skeleton.
2. Compare flat bones and long bones. How are they different? How are they the same?
They both have cortical bones. Long bones are longer than they are wide. Flat bones
, Lab 6 The Skeletal System BIO201L
tend to be curved and contain red marrow.
