The human skeleton is the internal framework for the human body. It consists of many individual bones and cartilages, as well as bands of fibrous connective tissue—the ligaments and the tendons—which serve in intimate relationship with the parts of the skeleton.
The skeleton acts as a scaffold by providing support and protection for the soft tissues that make up the rest of the body. The skeletal system also provides attachment points for muscles to allow movements at the joints.
Bones of the appendicular skeleton facilitate movement, while bones of the axial skeleton protect internal organs. All skeletal structures belong to either the appendicular skeleton (girdles and limbs) or to the axial skeleton (skull, vertebral column, and thoracic cage).
If you’re picturing your skeletal system, you might think of the plastic skeleton your science teacher used to keep in their classroom. It does contain all your bones, but your skeletal system has lots of other tissue, too.
The human skeleton can be divided into the axial skeleton and the appendicular skeleton. The axial skeleton is formed by the spinal column, the rib cage, the skull, and associated bones.
At first glance, the human skeleton appears simple—a rigid scaffolding made of bone. But in reality, it’s a marvel of diverse tissues and complex structures working harmoniously. Bone itself is a unique composite material, combining strength and flexibility.
Humans are unique among primates in that they alone practice obligatory bipedalism and their skeletons show distinctive adaptations for this form of locomotion.
