Lab 6 The Skeletal System BIO201L
Student Name: Gloria Arajulu
Access Code (located on the lid of your lab kit): AC-OF2X1AP
Pre-Lab Questions:
1. List the functions of the skeletal system.
Supports and protects the body, stores nutrients, produce new blood cells, and enable
movement
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.
Bone remodeling creates a new bone and removes old bones. It starts with a resting stage ->
bone resorption -> transition stage -> bone formation.
Experiment 1: Classification of Bones
Table 6: Classification of Bones
Bone Name Classification by Shape Classification b y Location
Scapulae Flat bone appendicular
Femur Long bone axial
Frontal Flat bone axial
Vertebral Column Irregular bone axial
Carpals Short bone appendicular
Patella Seisamoid bone appendicular
Ribs Flat bone axial
Tibia Long bone appendicular
Fibula Long bone appendicular
Ulna Long bone appendicular
Post-Lab Questions
1. Why is it important to classify bones?
Classifying bones is important to understand their structure, function, and role in the
human body. It helps in identifying bone types, providing insights into
their developmental patterns, and guiding medical diagnoses and

treatments. Additionally, bone classification aids in studying skeletal systems across various
species, contributing to broader biological and

anatomical knowledge.
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?
In addition to length, long bones typically have a shaft (diaphysis) and two expanded ends
(epiphyses). They are primarily associated with the appendicular skeleton, forming the bones
of the arms, legs, hands, and feet.
3. Compare flat bones and long bones. How are they different? How are they the same?
Flat bones are thin and flat, while long bones are longer with a shaft and expanded ends.
Both types serve different functions in the body: flat bones provide protection and
attachment sites for muscles, while long bones support weight and facilitate movement.
