STRUCTURE OF THE HUMAN SKELETAL SYSTEM
The human skeletal system is the internal structural framework of our body. At birth, it is composed of approximately 270 bones. This total decreases to approximately 206 bones by adulthood after certain bones fuse together. The precise number of vertebrae differs from human to human as the two lower sections, sacral and coccygeal, may vary in length.
FUNCTIONS OF THE HUMAN SKELETAL SYSTEM
The human skeletal system serves six major functions. For the purpose of our dialogue, the three most important functions are:
STRUCTURAL SUPPORT
The human skeletal system functions to provide a fundamental structural framework. This structural framework supports the entire body and maintains its shape. All internal organs, musculature, and other tissue are attached, directly or indirectly, to the fundamental structural framework of the human skeletal system.
FACILITATION OF MOVEMENT
The human skeletal system functions to make locomotion possible. Joints between bones are connected by ligaments that allow for movement of the structural framework itself. Movement is powered by skeletal muscles, which are attached to the skeleton at various sites on bones via tendons. Bones, joints, ligaments, muscles, and tendons provide the principal mechanics for movement, which is coordinated by the nervous system.
PROTECTION OF MAJOR ORGANS
The human skeletal system functions to protect many vital internal organs, joints, musculature, nerves, and other tissue from damage.
CONCLUSION
With a profound understanding concerning the fundamental anatomical structure and function of our physical structural framework, we can proceed toward learning about the the fundamental anatomical structure and function of our vertebral column.

The human skeletal system functions to protect many vital internal organs, joints, musculature, nerves, and other tissue from damage.
- The cranium protects the brain, the eyes, the middle ears, and inner ears.
- The vertebrae protect the spinal cord.
- The clavicle and scapula protect the shoulder joint.
- The rib cage, spine, and sternum protect the lungs, heart, and major blood vessels.
- The ilium and spine protect the hip joint, digestive organs, and urogenital organs.
- The patella and the ulna protect the knee and the elbow joints respectively.
- The carpals and tarsals protect the wrist and ankle joints respectively.
CONCLUSION
With a profound understanding concerning the fundamental anatomical structure and function of our physical structural framework, we can proceed toward learning about the the fundamental anatomical structure and function of our vertebral column.
