Question

Diffrrebtiate between reflex action and normal functions of the brain

Answer 1

Answer:

here your answer

An involuntary response on stimulation of the peripheral nervous system which requires the involvement of a part of the central nervous system is called reflex action. The afferent neuron receives a signal from a sensory organ. It then transmits the impulse to the spinal cord via the dorsal root.

Answer 2

Reflex action does not involve a brain to think. Normal brain function can take time to perform.

Explanation:

It is a sudden movement or response to a stimulus that occurs within a very short period of time (usually within a second) and does not involve a will or brain thinking called a reflex action. For example. If we touch a hot plate, we will suddenly take our hand back. Here, taking your hand back is a reflex action.

Normal brain function does not only include functions that are sudden or very quick. They can take time to perform. But a reflex action is taking place very quickly.
