Regarding NEURAL REGULATION OF RESPIRATION - choose the incorrect statement :

asked Apr 3, 2014 by pady_1

1 answer

NEURAL REGULATION OF RESPIRATION : 1. A specialised centre present in the medulla region of the brain called respiratory rhythm centre is primarily responsible for this regulation. 2. Pneumotaxic centre present in the pons region of the brain. Neural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. Regarding 1 and 2 :
