NCERT Solution Class X Science Control and Coordination Question 10 (Ex 7.4)

Question 10:

How are involuntary actions and reflex actions different from each other?

Answer:

Involuntary actions cannot be consciously controlled. For example, we cannot

consciously control the movement of food in the alimentary canal. These actions

are however directly under the control of the brain. On the other hand, the reflex

actions such as closing of eyes immediately when bright light is focused show

sudden response and do not involve any thinking. This means that unlike involuntary

actions, the reflex actions are not under the control of brain.
