B Correct answer
Explanation

Emotion involves two parts of the nervous system - the limbic system and the autonomic nervous system. The limbic system is a complex set of structures, that lies on both sides of the thalamus, just under the cerebrum. It includes the hypothalamus, the hippocampus, the amygdala. The hypothalamus feeds information into the amygdala. The hypothalamus acts as a regulator of emotion, controlling levels of sexual desire, pleasure, aggression and anger.

B Correct answer
Explanation

The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The occipital lobes are part of the forebrain. A significant functional aspect of the occipital lobe is that it contains the primary visual cortex. The optic lobes are especially prominent in fish and birds.

The part of the brain, which shows progressive increase in size, from a fish to mammals is 

  1. Cerebrum

  2. Olfactory lobes

  3. Optic lobes

  4. Medulla oblongata
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

As we move from fish to mammals, there is an observable increase in the brain size relative to the body size. This progressive increase is mainly observed in the form of an increase in the size of cerebral hemispheres or the cerebellum. So, the correct answer is 'Cerebrum'.
