What is responsible for rhythm generation of inspiration?
Dorsal nucleus of vagus
Pre botzinger complex
ventral respiratory neurons
Pneumotaxic center
Ans. B. Pre botzinger complexRhythmic respiration is initiated by a small group of synaptically coupled pacemaker cells in the pre-Botzinger complex (pre-BOTC) on either side of the medulla between the nucleus ambiguus and the lateral reticular nucleus.The main components of the respiratory control pattern generator responsible for automatic respiration are located in the medulla.Rhythmic respiration is initiated by a small group of synaptically coupled pacemaker cells in the pre-Botzinger complex (pre-BOTC) on either side of the medulla between the nucleus ambiguus and the lateral reticular nucleus.
