Structure Of Bone

1. Reexamine the microscopic structure of bone tissue by observing a prepared microscope slide of ground compact bone. Use the figures of bone tissue in a textbook to locate the following features:

osteon (Haversian system)

osteonic canal (Haversian canal)

lamella lacuna (small chamber for an osteocyte) canaliculus

Critical Thinking Application

I Explain how bone cells embedded in a solid ground substance obtain nutrients and eliminate wastes.

2. Review a textbook section on bone structure.

3. As a review activity, label figures 11.1 and 11.2.

4. Observe the individual bone specimens and arrange them into groups, according to the following shapes:

long short flat irregular sesamoid (round)

Figure 11.1 Label the major structures of this long bone (femur).

Epiphyseal disks

Space occupied by red marrow

Epiphyseal disks

Space occupied by red marrow

Locate Epiphyseal Disk

5. Complete Part A of Laboratory Report 11.

6. Examine the sectioned long bones and locate the following:

epiphysis (proximal and distal)

epiphyseal disk articular cartilage diaphysis periosteum compact bone spongy bone

trabeculae medullary cavity endosteum yellow marrow red marrow

7. Use the dissecting microscope to observe the compact bone and spongy bone of the sectioned specimens. Also examine the marrow in the medullary cavity and the spaces within the spongy bone of the fresh specimen.

8. Complete Part B of the laboratory report.

Figure 11.2 Label the features associated with the microscopic structure of bone.

Figure 11.2 Label the features associated with the microscopic structure of bone.

DEMONSTRATION

E xamine a fresh chicken bone and a chicken bone that has been soaked for several days in vinegar or overnight in dilute hydrochloric acid. Wear disposable gloves for handling these bones. This acid treatment removes the inorganic salts from the bone matrix. Rinse the bones in water and note the texture and flexibility of each. Based on your observations, what quality of the fresh bone seems to be due to the inorganic salts that were removed by the acid treatment?_

Examine the specimen of chicken bone that has been exposed to high temperature (baked at 121°C/250°F for 2 hours). This treatment removes the protein and other organic substances from the bone matrix. What quality of the fresh bone seems to be due to these organic materials? _

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
