Answer 2

Answer:  

Human spinal cord has an automatic reaction to external stimulus and does not require thinking.  

Explanation:  

An instantaneous movement that is involuntary is known as the reflex action, and this occurs as a result of an external stimulus. Our brains along with the spinal cord are responsible for the carrying out of these reflex movements.

When a sudden bright light is witnessed, the size of the pupil gets smaller and this is an example of the reflex action. Also, when a pin is pricked an involuntary automatic response occurs in our hands or legs and this too is a reflex action.
