Sensory Receptors Convert _____ into _____ by Signal Transduction

Question

Sensory receptors convert _____ into _____ by signal transduction.
A)neurotransmitters; synapses
B)physical or chemical stimuli; nerve impulses
C)physical stimuli; sound
D)neurons; sensory organs

Accepted Answer

Sensory receptors are specialized cells that detect various kinds of physical or chemical stimuli, such as heat, light, sound, touch, pressure, and chemicals. These stimuli are converted into nerve impulses by signal transduction, which involves the activation of receptor proteins, opening of ion channels, and generation of action potentials. The nerve impulses are then transmitted along sensory neurons to the central nervous system, where they are processed and integrated to produce sensory perceptions, such as vision, hearing, touch, taste, and smell. Therefore, option B is the correct answer as it explains the conversion of physical or chemical stimuli into nerve impulses.
