Functions of the Skeletal System

Objective 9.1

9.1.1 Describe the general functions of the skeletal system.

 

When you think of the skeletal system, you probably picture individual bones or maybe the whole skeleton (like something from a Halloween display). There is more to the skeletal system than we generally realize. Yes, it does hold us up and allow us to move, but it has some other, just as important functions, as well.

The six functions of the skeletal system are listed here.

This table describes the general functions of the skeletal system.

We will cover the first four functions in this unit: support, movement, protection, and mineral homeostasis. Protection varies between organs. For example, the brain and spinal cord are fiercely protected by the skull and vertebral column; the heart and lungs are well-protected by the vertebral column and ribs; and the intestines receive no bony protection at all, which is a gut punch for these essential organs.

Hematopoesis will be discussed in Unit 15.

Fat storage is not an important part of our story in this course, and will be mentioned only in passing.
