Question

What is meant by reflex-action? With the help of a labelled diagram trace the sequence of event which occurs when we touch a hot object.

Answer 1

Reflex action is a spontaneous response needed in the sudden adverse situation. It is controlled by the spinal cord. The integration of the impulse takes place in the spinal cord and sudden protective response is demonstrated by the spinal cord as illustrated by the diagram.

The diagram shows the reflex action when a hot body is touched.
