A mechanical pressure was exerted on a specific location of a peripheral nerve of a mammal. The touch or pain receptors were stimulated from the skin surface innervated by the same nerve. The action potential generated by touch receptor stimulation was blocked beyond the point of mechanical pressure. But the action potential generated by pain receptor stimulation passes through the point of mechanical pressure. Following explanations were offered for these observations: P. The large diameter 'A' fibres were affected by mechanical pressure Q. The small diameter 'C' fibres were not affected by mechanical pressure R. The Intermediate diameter 'B' fibres were affected by mechanical pressure S. The large diameter 'A' fibres were not affected by mechanical pressure Which of the above combinations Is correct?
