Question

When we happen to touch a hot object, the sensory nerve immediately passes a
message to the
eves.​

Answer 1

Answer:

Spinal cord takes the action when we touch hot objects.

Answer 2

When you touch a hot object or when a pin pricks your finger, what is your immediate reaction? Of course, you remove your hand away from the source of pain, either the hot object or the pin. In situations like these, your reactions are always immediate, involuntary and sudden. They happen without much of a thinking process. In scientific terms, this action is called the reflex action. Here the spinal cord has a major role to play.  The reflex arc shows the pathway through which the reflex action occurs.

The whole mechanism of reflex action occurs in such a fashion that there is no conscious control of the brain
