![]() The brain is only aware of the signal and the response that has taken place. Reflex arcs are formed in the spinal cord and the information (input) reaches the brain. The reflex arcs -connections present beween the input and output nerves - meet in a bundle in the spinal cord. Such a connection of detecting the signal from the nerves (input) and responding to it quickly (output) is called a reflex arc. ![]() The sensory nerves that detect the heat are connected to the nerves that move the muscles of the hand. For example, when we touch a hot object, we withdraw our hand immediately without thinking as thinking may take time which would be enough to get us burnt. Solution : Reflex actions are sudden responses, which do not involve any thinking. What is the role of brain in reflex action? Then, the forebrain interprets it by putting it together with the information received from other receptors and also with the information already stored in the brain.ĥ. When the smell of an incense stick reaches us, our forebrain detects it. The forebrain also has regions that collect information or impulses from the various receptors. It has separate areas that are specialized for hearing, smelling, sight, taste, touch, etc. Solution : The thinking part of our brain is the forebrain. How do we detect the smell of an agarbatti (incense stick)? Solution : Cerebellum, a part of hindbrain is responsible for maintaining posture and equilibrium of the body.Ĥ. Which part of the brain maintains posture and equilibrium of the body? From axon, the impulses travel across the synapse to the dendron of the other neuron.ģ. This uni-direction transfer of impulses occurs as the chemicals are produced in only one side of the neuron i.e., the axon's side. It acts as a one way valve to transmit impulses in one direction only. Solution : A very small gap that occurs between the last portion of axon of one neuron and the dendron of the other neuron is known as a synapse. What happens at the synapse between two neurons? Solution : Difference between reflex action and walking:Ģ. What is the difference between a reflex action and walking? ![]() Here all chapter lists with detailed examples for NCERT Solution for Class 10 Science.ġ. ![]() NCERT Solutions are accessible in PDF format on Physics.
