dental pulp innervation

This histological image clearly demonstrates this specialized nerve network located primarily within the cell-free zone of Weil, just beneath the odontoblast layer of the dental pulp. The plexus consists of densely packed unmyelinated nerve fibers that form an intricate meshwork before sending terminal branches toward the odontoblast layer and into dentinal tubules. This arrangement facilitates the tooth's sensory function, allowing it to respond to various stimuli including temperature changes, mechanical pressure, and chemical irritants.
