Question

What is the role of the brain in reflex action?

Answer 1

Reflex action:

1. Reflex acts are quick reactions.
2. It's an unintentional activity that doesn't require any thought.
3. When we touch a hot object, for example, we instinctively remove our hands without thinking.
4. The nerves that move the muscles of the hand are related to the sensory nerves that feel the heat.

The role of the brain in reflex action:

1. A reflex arc is a connection between perceiving the signal from the nerves and promptly responding to it.
2. In a reflex action, the brain plays no part.
3. The spinal cord, which reacts without thinking about how to respond to stimuli, is in charge of these automatic actions.
4. It elicits no meaningful response in the brain.
