A bstract — The neural tissue in human periodontium is associated with the terminal part of a norve trunk from which myelinated nerve fibres leave and in some instances divide into three or more nerve fibres. Encapsulated myelinated nerve fibres lose their myelin sheaths and encircle the adjacent myelinated nerve fibres to form compound meehanoreceptors approximately 35 × 45 μm. Simple mechanoreceptors of approximately 10 × 10 μm consisted of single myelinated nerve fibres surrounded by cell bodies and terminated as encapsulated unmyelinated nerve fibres. A cluster of compound mechanoreceptors formed a complex approximately 100times 150 μm. An arterial system appeared to supply nutrition for the compound receptors, whilst an arcade of veins surrounded the neural complex.
