The diagram shows a section through the human brain:
What are the names of the parts labelled 1, 2 and 3?

- A
Option A: Cerebrum, Cerebellum, Medulla
- B
Option B: Frontal Lobe, Parietal Lobe, Occipital Lobe
- C
Option C: Thalamus, Hypothalamus, Pituitary Gland
- D
Option D: Pons, Midbrain, Medulla Oblongata
The correct answer is Option B: Frontal Lobe, Parietal Lobe, Occipital Lobe. These parts are distinct regions of the cerebral cortex, each with specific functions: the frontal lobe is involved in executive functions and decision making, the parietal lobe processes sensory input, and the occipital lobe is primarily responsible for visual processing. Options A, C, and D refer to different brain structures or regions that do not match the labelled parts in the diagram.
This option correctly identifies the parts. The cerebrum is the largest part of the brain, the cerebellum is involved in balance, and the medulla controls basic life functions.
These are the incorrect names of the parts labelled. The frontal lobe is responsible for cognitive functions, the parietal lobe processes sensory information, and the occipital lobe is involved in vision.
This option incorrectly identifies the parts. The thalamus relays sensory information, the hypothalamus regulates homeostasis, and the pituitary gland is the master endocrine gland.
This option incorrectly identifies the parts. The pons bridges various parts of the nervous system, the midbrain is associated with vision and hearing, and the medulla oblongata controls autonomic functions.
