Think About It

The intervertebral joints are symphyses only in the cervical through the lumbar region. How would you classify the intervertebral joints of the sacrum and coccyx in a middle-aged adult?

6syn = together + chondr = cartilage + osis = condition

7 sym = together + physis = growth

Synchondrose Sternum

Figure 9.5 Cartilaginous Joints. (a) Synchondroses, represented by costal cartilages joining the ribs to the sternum; (b) the pubic symphysis; (c) intervertebral discs, which join adjacent vertebrae to each other by symphyses. What is the difference between the pubic symphysis and the interpubic disc?

Before You Go On

Answer the following questions to test your understanding of the preceding section:

4. Define suture, gomphosis, and syndesmosis, and explain what these three joints have in common.

5. Name the three types of sutures and describe how they differ.

6. Name two synchondroses and two symphyses.

7. Give some examples of joints that become synostoses with age.

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.
