Skeletal System

Meaning

The biological framework of the human body composed of bones, cartilage, ligaments, and tendons, which provides structural support, protection for internal organs, and surfaces for muscle attachment to facilitate movement. Beyond its mechanical functions, the skeletal system is a dynamic endocrine organ, serving as the primary reservoir for calcium and phosphate and producing hormones like osteocalcin that influence metabolism. It is a fundamental system of human anatomy and physiology.
