Explanation / Answer

7. Corpus Callosum is a thick band of nerve fibers that divides as well as connects the two hemispheres of brain. Its main function is to transmit messages between the two hemispheres. It is the largest collection of white matter as well as has high myelin content.

8. Cerebral Cortex, or the cerebrum, is divided into the following 4 lobes:

9. Left side brain functions - Logic, reasoning, analysis, language, numbers, writing, and right-side body control

Right side brain functions - Creativity, artistic abilities, intuition, judgement, insight, holistic thoughts, music awareness, recognition of 3D forms, and left side body control.

a. Left side brain

b. Right side brain

c. Right side brain

d. Left side brain

e. Right side brain

f. Left side brain

10. a. Occipital lobe

b. Parietal lobe

c. Temporal lobe (with a small area of Frontal lobe involved)

d. Frontal lobe

Bonus - Actions that take place without the input from brain are called reflexes. But most of the reflexes involve the input from brain, but those reflexes in which information passes only till spinal cord and not involve brain is called as true reflex arc. Reflex arc involves following components that work together to form a reflex -

So, in a reflex arc, brain does receive the sensory input while the reflex action is occurring, but it is not directly involved in the action. This is to cut short the time for occurrence of reflex by cutting down processing. Reflexes are instantaneous this is due to non-involvement of brain.
