Which of the following is not the reason for greater
susceptibility of smaller sensory fibres to blockade
by local anaesthetics than larger motor fibres:
A. Sensory fibres are inherently more sensitive
than motor fibres
B. More slender fibres have shorter internodal
distances
C. Small sensory fibres generate higher
frequency longer lasting action potential
D. Smaller fibres have shorter critical lengths
for blockade
