Question

Definition of dentin, odonto blast, pulp cavity, blood vessels in simple language

Answer 1

Dentin: The hard tissue of the tooth that surrounds the central core of nerves and blood vessels
mesenchyme of neural crest origin, lining the pulp cavity of a tooth; odontoblasts are arranged in a peripheral layer in the dental pulp, each with an odontoblastic process extending part way into the dentinal tubules; the cells generally are columnar in the coronal pulp but are more cuboidal in the radicular area and adjacent to tertiary dentin.
The blood vessels are part of the circulatory system and function to transport blood throughout the body
pulp cavity - the central cavity of a tooth containing the pulp (including the root canal)
