Answers
Answer:
Components of Reflex action :
• Heat/pain receptors in skin.
• Sensory neuron.
• Inter neuron.
• Motor neuron.
• Effector organs.
Reflex Action:
•The purpose of reflex action is to provide quick response in situations where the organism doesn't have enough time to think .
•Reflex arcs are formed in the spinal cord , although the information inputs also reach the brain .
• This helps the brain to record this event and remember it for the future use.
• The information about the reflex action is sent to the brain after 1 or 2 seconds.
• This is so that we should be aware of what has happened.
• The brain on its own cannot react as fast as the reflex action.
• So the part of the reaction process is carried out by the spinal cord , but the information is also sent to the brain so that the person can be aware of the stimulus and prevent himself from that situation again.
• For example: you remove your hand when touching a hot object.this is a reflex action.
But sending the information to the brain makes the person aware that the object is hot and hence not to touch it again.
