Q. No. 5: What is the role of
the brain in reflex action?
Ans: Reflex actions
are sudden responses. It is involuntary action which does not involve thinking.
For example, when we touch a hot object, we withdraw our hand immediately
without thinking. The sensory nerves that detect the heat are
connected to the nerves that move the muscles of the hand. Such a connection of
detecting the signal from the nerves (input) and responding to it quickly
(output) is known as reflex arc. Reflex arcs are formed in the spinal cord and
the information reaches the brain and the brain responses to it. |

DeleteBrain has no direct involvement in reflex action. the reflex action is mainly controlled by spinal cord ,as these actions do not involved thinking and are very quick in action only the information about signal and response that takes place reaches the brain .the brain, as such ,has no role in reflex action
Deletebrain does no play any role in reflex action
ReplyDeletebrain does no play any role in reflex action
ReplyDeleteYou are wrong actually if the brain will not get the information only you will not come to know what happened. Spinal cord takes decision so body part does not gets harm but brain is still informed.
Deletenooooo
Deletebrain has its role in cerebrum reflexes
DeleteBrain does not play any role in reflex action but controls the movement made by the reflex action . This indirectly it plays an role in reflex action
ReplyDeleteBrain does not control reflex movement rather the sensory nerves do directly....the brain just gets the information afterwards so that we perceive the action as it is.
DeleteYes

ReplyDeleteTotally Coonnffuussed.....
ReplyDeleteThanks for the answer it is nice
ReplyDeleteBrain doesn't involved in reflex action but it controls the movements made as a result of reflex action uptp some extent.
ReplyDeletei don't think so because brain merely record that incident to avoid the same circumstance if it would be in future.
DeleteFabulous job
ReplyDeleteBrain has role in reflex action that is the brain store the memory of reflex action
ReplyDeleteTry to give better answers... thank you
ReplyDeleteWell as we know spinal chord acts as a semiautonomus organ at a time of rflx action it responds to stumli but it us upto brain to order any part to act independently hance brain hasan inderect role in reflx action
