Which one of the following statements about sense receptors is true?
A)Chemicals, light and pressure
convert stimuli into electrical
B) Electrical impulses within the nerve pathways trigger an awareness of stimuli in the sensory receptors
C)Sensory receptors are located in the body's "command center" (the brain)
D) Sensory receptors are the primary cause of the common condition called synesthesia.
I am confused between A and B
Think of what stimuli are - external factors that have an effect on the body. The receptors 'feel' the stimuli. Read A again - what are chemicals, light, and pressure? Can they convert stimuli? Read B again - can receptors become aware of stimuli?
Receptors are responsible for transduction, converting stimuli to electrical impulses, e.g., rods and cones in the eye.
