Question
Sensory receptors are specialized to perceive a certain kind of
- Stimulus
- Chemical
- Light
- Touch
Hint:
The sensory receptors are very sensitive to various senses around them.
The correct answer is: Stimulus
- The sensory receptors are specialized in such a way that they perceive a certain kind of stimulus.
- Stimulus refers to a detectable change in the physical or chemical environment. This could be a change in light, sense of touch, etc.
- The sensory receptors belong to the nervous system. As soon as there is a change in the external environment, these receptors get activated. They, then convert the energy received from the stimulus to electrical energy. And these electrical signals get transported by the help of neurons to the brain for decoding.
The electrical signals are also known as action potential, which is transferred to the brain for decoding.
