Which part of the brainstem contains the medulla respiratory group?

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

Answer: (C)

The medulla respiratory group is located in the medulla oblongata, which is the correct answer. This region of the brainstem is crucial for the regulation of breathing because it contains the neural centers responsible for generating and controlling the rhythm of respiration. The medulla oblongata integrates sensory information regarding carbon dioxide and oxygen levels in the blood, facilitating the appropriate adjustments to the depth and rate of breathing. The medulla respiratory center works in coordination with the pons, which also plays a role in respiratory control but is not where the primary respiratory group is situated. This functional distinction highlights the importance of the medulla oblongata specifically in the autonomic control of breathing.
