Peripheral chemoreceptors (the carotid and aortic bodies) can sense hypercapnia (high CO2) and then they send a signal to the breathing centre. Breathing centre is in medulla oblongata which regulates breathing movements. When CO2 reaches a certain level, a signal is sent to trigger an inhalation and the rate of breathing is increased.</span>
<span>Transmitted via neurotransmitters. There is a gap between two neurons. This place where the axon meets with dendrite is callde synapse. Neurotransmitters which are chemicals help transmit the signals from axon to dentrite. Calcium ions play major role in this process.</span>
