- The Skeletal System Consists Of More Than Bones. When you look at the human skeleton the 206 bones and 32 teeth stand out. But look closer and you’ll see even more structures.
- The Adult Human Skeleton Is Made Up of 206 Bones. These bones provide structure and protection and facilitate motion. Bones articulate to form structures.
- The Skeleton Protects Vital Organs. The brain is surrounded by bones that form part of the skull. The heart and lungs are located within the thoracic cavity, and the vertebral column provides structure and protection for the spinal cord.
- Interactions Between the Skeleton, Muscles, and Nerves Move the Body. How does the skeleton move? Muscles throughout the human body are attached to bones.
The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. [1] The bone mass in the skeleton makes up about 14% of the total body weight (ca. 10–11 kg for an average person) and reaches maximum mass ...
- Skull. The skull is composed of 22 bones that are fused together except for the mandible. These 21 fused bones are separate in children to allow the skull and brain to grow, but fuse to give added strength and protection as an adult.
- Hyoid and Auditory Ossicles. The hyoid is a small, U-shaped bone found just inferior to the mandible. The hyoid is the only bone in the body that does not form a joint with any other bone—it is a floating bone.
- Vertebrae. Twenty-six vertebrae form the vertebral column of the human body. They are named by region: Cervical (neck) - 7 vertebrae. Thoracic (chest) - 12 vertebrae.
- Ribs and Sternum. The sternum, or breastbone, is a thin, knife-shaped bone located along the midline of the anterior side of the thoracic region of the skeleton.
