Principles of Anatomy and Physiology, 12th Edition, by Bryan Derrickson, Gerald Tortora. Multiple Choice &Essays 1. List and briefly describe the six main functions of the skeletal system. Ans: The skeletal system is used for support for the soft tissues of the body and as attachment sites for tendons of most skeletal muscles. The skeletal system also functions in protection for the internal organs. The skeletal system assists in movement working together with the muscle system. Skeletal system aids in mineral (calcium and phosphorus) homeostasis by storing several minerals and releasing them into the bloodstream on demand. Within some bones is red bone marrow that produces all blood cells. Bones are also a storage site for triglycerides throughout the body. Difficulty: medium Feedback: 6.1 2.
