Q. What is the skeleton mostly made of?
The adult human skeleton is made up of 206 bones. These include the bones of the skull, spine (vertebrae), ribs, arms and legs. Bones are made of connective tissue reinforced with calcium and specialised bone cells. Most bones also contain bone marrow, where blood cells are made.
Q. Are teeth part of the skeleton?

Q. Which is the hardest part of human body?
Tooth enamel
Q. What doesn’t grow as you age?

Q. Which body part grows after death?
Hair and fingernails may appear longer after death, but not because they are still growing. Instead, a persons fingernails and hair may appear longer because the skin around them has retracted, according to the Dermatology Clinic at UAMS.
