What is the role of sensory receptors?

• To produce action potentials

• To integrate sensory information

• To transduce stimuli into membrane potential changes

• To generate motor responses

What is the difference between sensation and perception?

• Sensation is the activation of sensory receptor cells, while perception is the central processing of sensory stimuli

• Sensation is the central processing of sensory stimuli, while perception is the activation of sensory receptor cells

• Sensation and perception are the same thing

• Sensation and perception are unrelated to each other
