Analyse the illustration and answer the following questions : Are all accidental responses controlled by (iii) ? Explain with an example.

A reflex arc is a pathway that controls a reflex in the body of a human. Sensory neurons pass through the spinal cord as most of them do not pass directly into the brain. This helps for faster reflex action. It allows the spinal motor neurons to get activated without the delay of signals through the brain. In the given diagram (iii) represents the spinal cord. Not all accidental responses are controlled by the spinal cord. For example, when light falls on our eyes or any object moves towards our eye we normally close our eyes. This response is under the control of the cerebrum.

Suitably arrange the information under the given headings. Evokes sensations. Coordinates the repeated movements during walking and running. Impulses from the different parts of the body are transmitted to and from the brain Coordinates muscular activities and maintains equilibrium of the body. Brain Spinal cord

The brain and spinal cord play an essential role in the coordination of the impulses in the body of a human. Neurons help to relay the stimulus between different parts of the body. The brain evokes sensations and coordinates muscular activities and maintains the equilibrium of the body. The spinal cord coordinates the repeated movements during walking and running and relays impulses from the different parts of the body are transmitted to and from the brain.
