Human skeletal system, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton.
The adult human skeleton is a framework of 206 bones and is anatomically divided into two parts, the axial skeleton and the appendicular skeleton.
Axial skeleton
It consists of the following 80 bones.
- Skull bone
- Facial bone
- Vertebrae bone

• Pectoral girdle: 4 bones (Scapula and clavicle)
• Arms and forearms: 6 bones (Humerus and radius)
