Answer 1

$\boxed{\colorbox{red}{Reflex action:-}}$

➡A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.

➡ A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.

$\boxed{\colorbox{red}{Reflex arc}}$

➡Reflex Arc. The neural pathway that controls the reflexes occurs through the reflex arc. It acts on an impulse even before it reaches the brain.

➡ Immediately, the spinal cord sends back signals to the muscle through the motor neuron.

Answer 2

Explanation:

Relflex Action:-

➡A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.

➡ A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain

➡Reflex Arc. The neural pathway that controls the reflexes occurs through the reflex arc. It acts on an impulse even before it reaches the brain.
