Witryna28 cze 2024 · Definition A neuron is a single nervous system cell that receives, processes, and transmits electrochemical messages from and to other cells. Neurons connect different areas of the central and peripheral nervous systems. Witryna18 mar 2024 · Breathing. It is an impulse that is semi-conscious in humans, but that is not so in other species (like dolphins). It supposes the impulse of open the airways in order to allow the entry of an oxygen supply (which allows our cells to stay alive) and the excretion of residues from cellular functioning. 3. Excretion.
