Solution
Vibration receptors, also known as Pacinian corpuscles, have the fastest axonal conduction velocity among the sensory neurons listed. These receptors are responsible for detecting mechanical pressure and vibration. They have large, myelinated axons, which allow for faster conduction speeds. The myelin sheath acts as an insulator, preventing the loss of electrical signals and thus increasing the speed of conduction.
