♡HOLA FRIEND♡

---->HERE YOUR ANSWER <-----

reflex action is defined as a spontaneous, automatic and mechanical response to a stimuli without the will of an individual. In such actions there is no involvement of the brain. All reflex actions are conveyed through the spinal cord by a path called reflex arc.

HELLO DEAR FRIEND

$\large \underline{Reflex \: action = > }$ Sudden action in response to something in the environment is called reflex action.

For example- When we touch a hot object, we withdraw our hand immediately without thinking.

The path through which signals are transmitted from a receptor to a muscle or a gland is called $\large \underline{reflex \: arc}$
