Alterations of the Musculoskeletal System - Chapter Summary and Learning Objectives

The musculoskeletal system includes bone, muscle and connecting tissue. Through the video lessons in this chapter, you can learn about the anatomy and function of the organs. You will get a look at the causes, symptoms and treatments of several diseases and conditions, including cancer, osteoporosis, arthritis and broken bones. By the conclusion of this chapter, you should have an understanding of:

  • Anatomy and structure of joints, the skeletal system and the muscular system
  • Types, causes, symptoms and treatments of various types of arthritis
  • Muscle and skeletal tumors
  • Types of broken bones and luxations
