Question 2 of 10
What is the largest organ of the human body?
Why, in question 1: How many bones does an adult body have?
The answer is 206. The number holds for most adults; a newborn has many more bony pieces, which fuse together as the child grows. Some people have a few extra bones, such as small extra bones in the feet, so the count can vary slightly.
More than half of the bones are in the hands and feet
Of the 206 pieces, 54 are in the two hands and 52 in the two feet. It is this number of small bones, connected by joints, that allows delicate movements like writing, buttoning a shirt, or balancing on tiptoe.
Bone is living tissue. It has blood vessels and nerves, stores calcium and phosphorus for the rest of the body, and inside it the bone marrow produces blood cells.
Although light, bone is very strong. It combines minerals, which give hardness, with collagen fibers, which give some flexibility, and that is why it withstands impacts without breaking easily.
The only bone in the body that does not articulate with any other is the hyoid, in the neck, just above the Adam's apple. It is held in place by muscles and ligaments and helps support the tongue.
