Web3 Nov 2024 · Potassium is a natural mineral and an electrolyte that the body needs for the muscles to work, including the muscles responsible for controlling your breathing and heartbeat. Generally, we get all the potassium we need from the food we eat, and the body uses whatever amount of potassium it needs. Web26 Nov 2024 · The neuromuscular junction, as the name indicates, acts as a bridge between the nervous system and the muscular system. It is a microstructure through which the process of contraction is initiated or halted in the muscles by the neurons.
