The structure and function of cells of the nervous system: 2% others, which are used to signal between cells (sodium, potassium & Chloride: float around on their own with either a positive or negative charge, the cell is also: 50% proteins (made from amino acids: proteins can be characterized by their function: enzyme, sensor, signal, regulatory, transport, defense & storage, proteins compose almost all things in a cell. 10% lipids: the membrane of a cell is a fancy soap bubble" and is a lipid bi- layer and nothing crosses this barrier, the membrane also has proteins with special functions embedded into them. Eukaryotic cells over the past centuries are generally the same. Mitochondria are responsible for extracting energy, replicate themselves and energy is stored within their molecular bonds. Cytoplasm is saltwater", anything within the membrane. Microtubules allow for the rapid transport of material throughout the neuron due to the long length of some neurons (2 meters in some cases)
