1-a Brain is a part of our nervous system. Its parts include cerebrum, cerebellum and medulla oblongata. Cerebrum is the thinking part of our brain. 2-c The light enters the eye through the black spot in the centre of the iris called pupil. 3-b Ear is the sense organ of our body that helps us to hear different sounds in our surrounding environment. When sound falls on the eardrum, it starts vibrating. 4-f The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain. It controls all involuntary actions. 5-e The cerebellum is located in the back of our brain. It helps with the coordination and movement related to motor skills, especially involving the hands and feet. It also helps in regulating body temperature, maintain posture, balance, and equilibrium. 6-d Reflex action is an involuntary, unplanned sequence or action and nearly instantaneous movement in response to a stimulus. The spinal cord along with the brain stem is responsible for the reflex movements. Column 1 Column 2 1 Cerebrum a. Thinking 2 Pupil c. Light enters the eye 3 Eardrum b.
