Detailed explanation-1: -In a reflex action, the brain plays no part. The spinal cord, which reacts without thinking about how to respond to stimuli, is in charge of these automatic actions.
Detailed explanation-2: -Blinking of eyes is not a reflex action, but it is involuntary action. A reflex action is one which occurs spontaneously whereas involuntary action happens without the conscious choice of an organism.
Detailed explanation-3: -The medulla oblongata can regulate the body’s blood pressure, pulse, and cardiac contractions based on the body’s needs. Lastly, it controls reflexes like vomiting, swallowing, coughing, and sneezing. Cerebellum: The cerebellum, also known as the little brain, is responsible for smooth, coordinated voluntary movements.
Detailed explanation-4: -Reflexes are unconscious responses, which means they are automatic and do not require the brain to create the action.
Detailed explanation-5: -Reflex action is an immediate and involuntary action taken against a certain stimulus. It is under the control of the spinal cord and is not controlled by the brain.
