Hi, I have a question and I hope anyone could answer it:
The following diagram is that of a human brain. Guidelines 1 to 5 indicate different parts of the surface of the brain and these are as follows:
1. Frontal lobe of cerebrum
2. Temporal lobe of cerebrum
3. Occipital lobe of cerebrum
4. Cerebellum
5. Medulla oblongata
Study the diagram and answer the following questions:
(i) What handicaps would result from:
(a) Damage toçart numbered 3.
(b) Damage to part numbered 4.
(ii) Mention one main function of each of the parts numbered 1,2, and 5.
(i) (a) The part numbered 3 is named as occipital lobe of cerebrum, which is the area of vision. If this part is damaged, the person is unable to see.
(b) The part numbered 4 is named as cerebellum, which is responsible for coordinating the muscular activity for body balancing. If this part is damaged, the body balancing during walking and running would be affected.
(ii) Function of part 1: It governs all mental activities (reason, will, memory, intelligence, higher feelings and emotions).
Function of part 2: It controls all voluntary action and is responsible for taste and smell.
Function of part 5: It controls several involuntary activities, such as heartbeat, breathing, peristaltic motion of the alimentary canal, dilation and concentration of blood vessels, etc.
