Question

The respiratory centre of the brain is located in:

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

Answer 1

Answer: (A), (B)

The correct options are
A Medulla oblongata
B Pons

Respiratory centres generate rhythmic pattern of breathing and are present in brain stem. The medullary respiratory centres constitute the primary respiratory centre and include two aggregates of neuronal cell bodies namely dorsal respiratory group and ventral respiratory group. They serve to provide output to respiratory muscles. Pontine respiratory centres are present in higher in brain stem in pons and are namely pneumotaxic centre and apneustic centre. Pontine respiratory centres modify the output from medullary centres.

Cerebellum serves to coordinate the voluntary movements of skeletal muscles as well as posture, balance and equilibrium. Cerebrum is the largest and uppermost division of brain.

It is the centre for higher thought processes required for learning, memory, language and speech.

Therefore, the correct answer is option A and B.
