Question

The number of bones in an adult human body is

Answer 1

Hint: Every single person has a skeleton made up of many bones. These bones give your body structure, let you move in many ways, protect your internal organs, and more.
It is composed of 270 bones at birth but later decreases to 80 bones in the axial skeleton and 126 bones in the appendicular skeleton.

Complete answer: Almost every bone in your body is made of the same materials:
The outer surface of the bone is called the periosteum
It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone.
The next layer is made up of compact bone. This part is smooth and very hard. It's the part you see when you look at a skeleton.
Within the compact bone are many layers of cancellous bone, which looks a bit like a sponge. Cancellous bone is not quite as hard as compact bone, but it is still very strong.
In many bones, the cancellous bone protects the innermost part of the bone, the bone marrow.
Bone marrow is sort of like a thick jelly, and its job is to make blood cells.

So the correct answer is- 206 bones.

Note: A baby's body has about 300 bones at birth. These eventually fuse (grow together) to form the 206 bones that adults have. Some of a baby's bones are made entirely of a special material called cartilage. Other bones in a baby are partly made of cartilage. This cartilage is soft and flexible.
During childhood, as you are growing, the cartilage grows and is slowly replaced by bone, with help from calcium.
