What is the role of the brain in reflex action?
Answer
Reflex action is an immediate or quick action or response .
It does not involve thinking, besides our actions do not feel like they are under our control .
And so, reflex action does not involve the brain
The process of reflex action is like
- The stimuli is sensed by the sensory receptors and sensory neurons generate impulses.
- These impulses reach the spinal cord
- The relay neuron in the spinal cord passes signals between neurons.
- The motor neurons pass the signals for response to the organ that needs to respond to stimulus.
The information input also goes on to reach the brain . But it is not involved in reflex action.
