B Correct answer
Explanation

The chemosensitive area near the rhythm center in the medulla is highly sensitive to changes in CO2 concentration and H+ ion concentration in the blood, which regulate the rate of respiration.

Brain stem is made of

  1. Mid brain, pons, cerebellum

  2. Mid brain, pons, medulla oblongata

  3. Diencephalon, medulla oblongata, cerebellum

  4. Cerebellum, cerebrum, medulla oblongata

B Correct answer
Explanation

The brain stem is anatomically composed of the midbrain, the pons, and the medulla oblongata. It connects the cerebrum to the spinal cord.

B Correct answer
Explanation

Statement (a) is correct (midbrain, pons, medulla). Statement (c) is correct (medulla controls vital functions). Statement (d) is correct (cerebellum maintains balance/gyroscope). Statement (b) is often debated in nomenclature, but (a, c, d) are clearly correct.
