Respiration centre of brain is stimulated by
1 Carbon dioxide content in arterial blood
2 Carbon dioxide content in venous blood
3 Oxygen content in venous blood
4 Oxygen content in arterial blood
Explanation:
Respiratory centre of brain is stimulated by \(\mathrm{CO}_{2}\) content in arterial blood

Which part of the brain contains the respiratory rhythm centre?
1 Cerebellum region
2 Brain stem region
3 Medulla region
4 Temporal region
Explanation:
A specialised centre present in the medulla region of the brain called respiratory rhythm centre is primarily responsible for the regulation of respiratory rhythm.

Pneumotaxic centre is present in
1 Pons
2 Medulla
3 cerebrum
4 Lungs
Explanation:
The pneumotaxic center, also known as the pontinerespiratory group (PRG), is a network of neurons in the rostral dorsal lateral pons. It consists of the Kölliker-Fuse nucleus and the medial parabrachial nucleus.

The impulse for voluntary muscles for forced breathing starts in
1 Medulla oblongata
2 Vagus nerve
3 Cerebellum
4 Cerebal cortex
Explanation:
The motor cortex within the cerebral cortex of the brain controls voluntary respiration (the ascending respiratory pathway). Voluntary respiration may be overridden by aspects of involuntary respiration, such as chemoreceptor stimulus and hypothalamus stress response. The phrenic nerves, vagus nerves and posterior thoracic nerves are the major nerves involved in respiration. Voluntary respiration is needed to perform higher functions, such as voice control.
