Synapse. 1. Anatomically speaking there is a favorable equilibrium (balance in breathing . The cerebellum is not only responsible for your ability to balance, but for movement, also. For this reason, the movements that provide or allow the flow of respiratory medium to the corresponding organ are generated by innate rhythmic programs that are carried out by specific neuronal structures and can operate independently of the higher brain centers. The pigment dampens the effects of not too great variations in arterial tO2, so it functions, in effect, as an oxygen reservoir that ensures the supply to the tissues as long as the arterial oxygen pressure is not reduced excessively. So when you breathe rapidly and shallowly, it can trigger feelings like anxiety, anger, or fear. Lets get to know What is Breathing and Respiration, before we get intowhat part of the brain controls breathing. During exercise or in response to needs that require greater intensity and ventilatory frequency, the activity of the inspiratory neurons will increase, causing contraction of the accessory inspiratory muscles, but also activating the expiratory neurons, which will induce contraction of the accessory expiratory muscles. In this system of counterweights, the pneumotaxic center dominates, which contributes to setting limits to inspiration, allowing expiration to proceed normally.
