Respirations are Primarily Controlled by The

Question

Respirations are primarily controlled by the
A) medulla oblongata.
B) cerebellum.
C) spinal cord.
D) frontal lobe.

Accepted Answer

The medulla oblongata, located in the brainstem, plays a key role in controlling respiratory functions such as breathing rate and rhythm. It receives information from chemoreceptors and other sensory receptors, and sends signals through the phrenic and intercostal nerves to control the diaphragm and muscles of respiration. The cerebellum and spinal cord also contribute to respiratory control to some extent, but the medulla is considered the primary respiratory center. The frontal lobe is not directly involved in respiratory regulation.
