Rigid outer shell is known as an exoskeleton, which supports an organism's shape.
Internal frame to which organs and soft tissues attach is called an endoskeleton.

Animals like mammals and birds possess an endoskeleton centered around an axial vertebral column.

Human skeleton reaches maximum mass around the age of 30 years.
At birth, the human skeleton has approximately 270 bones, which fuse to form 206 in adulthood.

Axial skeleton consists of the vertebral column, rib cage, skull, and associated bones.
