2 Section A Answer all questions in this section. You are advised to spend no more than 1 hour and 15 minutes on this section. 0 1 . 1 Describe how stimulation of a Pacinian corpuscle produces a generator potential. [3 marks] Scientists investigated the stimulation of a Pacinian corpuscle in the skin of a fingertip. The scientists applied two different pressures to the fingertip and recorded the changes in membrane potential of the Pacinian corpuscle’s sensory neurone. Figure 1 show...
