Describe functional areas of the cerebrum with the help of a neat and labelled diagram.

The functional areas of the cerebrum are: Frontal lobe: It consists of the motor area which controls voluntary activities. Broca's area is a model speech area that translates thoughts into speech and controls the movements of the tongue, lips and vocal cords. The association area related to intelligence, memory, judgement and problem-solving is found in the frontal lobe. Parietal lobe: The general sensory area associated with the sensation of temperature, touch, pressure, pain and speech is located on the post-central gyrus of the parietal lobe. Temporal lobe: Areas concerned with the sense of taste, sense of hearing and sense of smell are located on the temporal lobe. Occipital lobe: It carries the sensory visual area concerned with the sense of vision and the association visual area for perception, analysis and storage of information obtained by sight.

Give reason: The pancreas is a dual gland.

The pancreas is a dual gland or a heterocrine gland. This is because pancreas functions as both an endocrine and exocrine gland. In other words, the pancreas has the dual function of secreting hormones into blood (endocrine) and secreting enzymes through ducts (exocrine).
