Question

Which of the following structures is not part of the central core of the human brain?

• A. Medulla
• B. Temporal Lobe
• C. Pons
• D. Hypothalamus

Hint:

Remember, the lobes of the brain (temporal, frontal, parietal, and occipital) are cortical regions, distinct from the central core structures responsible for basic survival functions.

Answer 1

The Correct Option is B

The central core of the brain (also known as the brainstem and associated structures) includes:

• Medulla: Controls vital functions like breathing and heart rate.
• Pons: Involved in sleep and arousal.
• Midbrain: Coordinates sensory and motor functions.
• Reticular formation: Regulates alertness and consciousness.
• Thalamus and hypothalamus: Parts of the forebrain that manage sensory relay and homeostasis, respectively.

Note: The temporal lobe is part of the cerebral cortex and is involved in higher-level cognitive processes, making it not part of the central core.
