Question
Output from higher brain centers can bypass both the DRG and VRG and go directly to ___________ which controls the accessory muscles of respiration. Which issues output to the VRG to adjust the respiratory rhythm? This center bears the primary responsibility for generating the respiratory rhythm, but is influenced by several other centers Emotional states are integrated by ________ which generates an output that creates such respiratory variations as laughing and crying. The pH of the cerebrospinal fluid is monitored by which of these brainstem centers?Explanation / Answer
Answer:
16. Output from higher brain centers can bypass both the drg and vrg and goes directly to spinal integrating centers which controls the accessory muscles of respiration.
17. The dorsal respiratory group (DRG) is a integrating center that processes information from multiple sources and then issues output to the vrg to adjust the respiratory rhythm.
18. VRG bears the primary responsibility for generating the respiratory rhythm, but is influenced by several other centers.
19. Emotional states are integrated by the PRG, which generates an output that creates such respiratory variations as laughing and crying.
20. Central chemoreceptor monitors the pH of the cerebrospinal fluid.
