Central Pulp Cavity
The central region of coronal pulp exhibits large blood vessels (A) and an extensive arrangement of nerves (B) that arise from large nerve trunks (C) and ascend to the more peripherally-located plexuses. These structures are surrounded by a dense meshwork of fibroblasts and collagen fibers embedded in an interellular matrix. There are also numerous undifferentiated cells which may be called into action when a new odontoblast or fibroblast is needed. Macrophages are commonly found within the pulp aiding in its maintenance. Inflammatory cells may be present in varying numbers dependent upon the health of the tooth.
