Given what you already know about the sensation of pain, what is the expected change in membrane potential when pain is felt by sensory receptors? Select one: a. The nerve impulses increase in strength and lower the threshold potential. b. The nerve impulses occur more frequently, thereby transmitting more action potentials according to the intensity of pain. c. The nerve impulses occur more frequently and prevent neurons from entering the refractory period. d. The nerve impulses increase in strength, thereby making the maximum membrane potential higher than normal.

Which options are true regarding the gate control theory of pain? Select all that apply: a. Mechanoreceptor fibres synapse directly onto nociceptor fibres and potentiate incoming pain signals b. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and potentiate incoming pain signals c. Applying a mechanical stimulus, such as grabbing the injured area, will soothe the injury d. Mechanoreceptor fibres synapse directly onto nociceptor fibres and inhibit incoming pain signals e. Mechanoreceptor fibres synapse onto interneurons, which synapse onto nociceptor fibres and inhibit incoming pain signals f. Applying a mechanical stimulus, such as grabbing the injured area, is a natural defensive reaction, but does little to actually affect incoming pain signals.
