Reflex Arc

What are reflexes?

• Actions performed in response to a stimulus with conscious thought

• Actions performed in response to a stimulus without conscious thought

• Actions performed in response to a stimulus with deliberate actions

• Actions performed in response to a stimulus with decision making

How do reflexes help us?

• By minimizing potential damage to the body

• By involving the brain in the reflex actions

• By reducing the chances of being injured or killed

• By following a sequence that involves the brain

How are reflexes and the Central Nervous System related?

• They are not related

• Reflexes are controlled by the Central Nervous System

• Reflexes are independent of the Central Nervous System

• Reflexes are only related to the brain

What is a reflex arc?

• A sequence of actions performed in response to a stimulus

• A pathway followed by a reflex action

• A type of reflex that involves the brain

• A reflex that occurs in the spinal cord

How do reflexes prevent your eyes from being damaged?

• By involving the brain in the reflex actions

• By triggering muscles to contract and move away from the danger

• By following a sequence that involves the conscious part of the brain

• By sending information to the brain for processing
