what is reflex action and reflex arc explain with example in your own words
Answers
Explanation:
The motor nerve fibres relay the motor impulses from the central nervous system to the effector organs. Thus, an impulse travels a path during reflex action which is called reflex arc. Examples of reflex action are, i) Closing of eyes when strong light is flashed across them.
Hey mate here is your
Answer:
A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus. Reflex actions happen through the reflex arc, which is a neural pathway that controls the reflexes. The receptor here is the sense organ that senses danger. The sensory neurons pick up signals from the sensory organ and send them through other neurons which are interconnected. It is then received by the relay neuron which is present in the spinal cord. Immediately, the spinal cord sends back signals to the muscle through the motor neuron. The muscles attached to the sense organ move the organ away from danger. In reflex actions, the signals do not travel up to the brain.
