Nerve Cells. A nerve cell is also known as a neuron. It serves as the basic functional unit of the system. There are approximately 10 billion neurons in the human nervous system. In many ways, the neuron is just like any typical cell. It has a cell membrane and a nucleus. Its cytoplasm contains the usual organelles that you learned about in high school biology endoplasmic reticulum, mitochondria, storage vesicles, and the Golgi apparatus. 

The majority of CYP enzymes are located in a hydrophobic environment in the endoplasmic reticulum of cells, although cytosolic enzymes also exist, such as CYP101. In order to mimic the physiological environment of CYP enzymes, a number of groups have used phospholipids to construct biosensors such as DDAB, dimeristoyl-L-a-phosphatidylcholine (DMPC), dilauroylphosphatidylethanolamine (DLPE) and distearoylphosphatidylethanolamine (DSPE). Phospholipid layers form stable vesicular dispersions that bear structural relationship with the phospholipid components of biologically important membranes. By this way a membranous environment is created that facilitates electron transfer between the enzyme s redox center and the electrode. 

AMs are richly endowed with endoplasmic reticulum (ER). Following exposure to cigarette smoke hydrocarbons in the presence of asbestos, the ER synthesizes the enzyme aryl hydrocarbon hydroxylase. This enzyme converts biologically inactive hydrocarbons to metabolically active forms that, when excreted from the cell, react with the extracellular matrix materials.
