What is VRG and DRG?
Dorsal respiratory groups (DRG) Composed mainly of inspiratory neurons located bilaterally in the medulla, the DRG controls the basic rhythm of breathing by triggering inspiratory impulses. DRG nerves extend into the VRG, but the VRG neurons do not extend into the DRG.Click to see full answer. Beside this, what is the VRG?The ventral respiratory group…
Dorsal respiratory groups (DRG) Composed mainly of inspiratory neurons located bilaterally in the medulla, the DRG controls the basic rhythm of breathing by triggering inspiratory impulses. DRG nerves extend into the VRG, but the VRG neurons do not extend into the DRG.Click to see full answer. Beside this, what is the VRG?The ventral respiratory group (VRG) is a column of neurons located in the ventrolateral region of the medulla, extending from the caudal facial nucleus to -400µm obex. The VRG contains both inspiratory and expiratory neurons. The VRG appears to be a rhythm generating and integrative center.Also, how does the medulla and pons control breathing? The apneustic (stimulating) and pnuemotaxic (limiting) centers of the pons work together to control rate of breathing. The medulla sends signals to the muscles that initiate inspiration and expiration and controls nonrespiratory air movement reflexes, like coughing and sneezing. In this manner, what is the function of the Apneustic Center? The apneustic center sends signals to the dorsal group in the medulla to delay the ‘switch off’, the inspiratory off switch (IOS) signal of the inspiratory ramp provided by the pneumotaxic centre. It controls the intensity of breathing, giving positive impulses to the neurons involved with inhalation.What controls the basic rhythm of breathing?Respiration is controlled by the respiratory center in the brain stem in response to CO2 levels. Medulla Oblongata sets the basic rhythm of breathing (pacemaker).
