Question

When a person is suddenly pushed from height by an attacker, his blood pressure and heart rate increase. Control through which centre of brain would normalise his condition?

• A. Medulla oblongata
• B. Pons
• C. Cerebellum
• D. Cerebrum

Answer 1

The correct option is A Medulla oblongata

There are numerous clusters of neurons which control specific activities of the internal organs in the medulla oblongata. Breathing, swallowing, heart rate, blood pressure, and equilibrium all have centres here. These cell clusters are called centres: those concerned with the heart are the cardiac accelerator centre and cardiac depressor centre. The functions of the medulla are so essential to life that serious disease in this area is usually terminal. Breathing, swallowing, heart rate, blood pressure, and equilibrium all have centres here.

So the answer is 'Medulla oblongata'.
