Human Skeleton

6.3 Human skeleton

Humans have a living endoskeleton (internal skeleton) made of bone, cartilage and connective tissue. At birth, the human skeleton consists of over \(\text{270}\) bones. However, in adults this number has reduced to \(\text{206}\) bones due the fusion of smaller bones into larger structures. The adult skeleton (see figure below) is made up of the axial skeleton and the appendicular skeleton (see figure below).
