Pons helps to relay messages from cortex and cerebellum.

Mid brain helps in motor movement especially movement of eye and in auditory and visual processing.

Cerebrum helps in thought and action

16. B) Longitudinal fissure seperate right and left cerebral hemisphere

Central fissure seperate the parietal lobe from frontal lobe.

Parieto-occipital fissure seperate between parietal lobe and occipital lobe.
