Output from higher brain centers can bypass both the DRG and VRG and go directly to __________,which controls the accessory muscles of respiration.
A) the diaphragm
B) spinal integration centers
C) the cerebral cortex
D) the vagus nerve

Question

Quizplus · Accepted Answer

Spinal integration centers receive direct input from higher brain centers to control the accessory muscles of respiration, bypassing the direct respiratory centers like the Dorsal Respiratory Group (DRG) and Ventral Respiratory Group (VRG). This allows for the coordination of more complex respiratory movements, such as those involved in speech or exercise.
