Tooth enamel, finger nails and bones .these things living or dead?

Did you know that when a person dies, their fingernails and hair keep growing. Now the bones, I know that the bone marrow dies, I don't know about tooth enamel.Tooth enamel, finger nails and bones .these things living or dead?
I would have to say that this is like hair. The part you see is actually dead...but the root is the actually living part as it grows.Tooth enamel, finger nails and bones .these things living or dead?
Finger Nails-Dead


Tooth Enalem- Alive, not sure


Bones-a.Bone marrow-alive with stem cells


b. superficial side of the bone-calcium deposits-dead
ALIVE.
A tooth is composed of four dental tissues: enamel, dentin and cementum, which are hard or calcified, and pulp, which is soft or noncalcified. The visible part of the tooth is called the crown. It is made of enamel, an extremely hard, non-living substance. Because it contains no living cells, tooth enamel cannot repair damage from decay or from wear. Only a dentist can correct these conditions.

and i think finger nail and bones are nonliving.
the things that are on the outside of your body are dead. Thus the tooth enamel and nail. Because cells cannot surive without water surrounding them. They are not plant cells and have no cell wall to protect them.


But a bone is part dead and partly alive. The calcium deposit part is dead, but bone marrow is alive.


But this is all assuming we can all define what alive is.
tooth enamel-dead


finger nails-dead


bones-living





enamel is simply a covering and thus is not alive. Fingernails are dead cells that have been harden and pushed forward by growing cells underneath. Bone is a type of tissue that has a blood supply and repair/remodeling system so it is alive.
