Question

what are reflex actions

Answer 1

Reflex actions occur both from the brain and spinal cord which are the parts of the central nervous system. Most often these actions are mainly formed from the spinal cord. When sudden responses are required, instructions are given by the spinal cord itself. Impulses reach the brain only after that. Later conscious responses are made. 

Answer 2

A reflex action is defined as a unconsciousness without will and involuntary response of effective (muscles of glands) to certain stimules for example we sudden remove our hands on touching a very hot plate or if we accidentally step on something sharp, remove our foot away at once. In reflex action the message from a receptor relayed by a sensory nerve to spinal cord. The spinal cord send some other through motor nerves to the concerned muscle is called a reflex arc. the muscles on the receiving order contract and the hand is removed in case our hand happens to touch a hot utensil .
