Introduction to Chapter 6

Bones appear to be the most lifeless of body organs, and may even summon images of a graveyard. However, the bones within you are not the dead, dry bones that you may have seen. Rather, they are living, dynamic organs, and bone tissue is formed and remodeled throughout life. Without bones to form our internal supporting skeleton, we would all creep along the ground like slugs, lacking any definite shape or form. Along with its bones, the skeleton contains resilient cartilages, which we briefly discuss at the beginning of this chapter.

Module-level Objectives

As a result of the instruction in this module, students will be able to:

Describe the functional properties of the three types of cartilage tissue. (CO: #5)
Locate the major cartilages of the adult skeleton. (CO: #5)
Describe the functions of the skeleton and of bone tissue. (COs: #9, 15)
Name the major regions of the skeleton and describe their relative functions. (CO: #15)
Compare and contrast the four bone classes and provide examples of each class. (CO: #9)
Describe the gross anatomy of a typical flat bone and a long bone. Indicate the locations and functions of red and yellow marrow, articular cartilage, periosteum, and endosteum. (CO: #9)
Indicate the functional importance of bone markings. (CO: #9)
Describe the histology of compact and spongy bone. (CO: #9)
Compare and contrast intramembranous ossification and endochondral ossification. (CO: #9)
Compare the locations and remodeling functions of the osetoblasts, osteocytes, and osteoclasts. (CO: #9)
Describe the steps of fracture repair. (CO: #7)

(CO = Course Objective. This demonstrates the alignment from the module objective to the course objective[s].)
