The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation. Cells arise from pre-existing cells. Mitosis is much shorter than interphase, lasting perhaps only one to two hours. Cell-mediated immunity is an immune response that does not involve antibodies. This allows cells to interact with one another, allowing molecules to travel between plant cells. As I have said, at the neuronal level this communication entails the sending of chemical messengers, called neurotransmitters Sickle cell disease is an inherited blood disorder. Now while the structure and the function of the little myelin segments is the same, a big difference between the Schwann cells in the peripheral nervous system and the oligodendrocytes in the central nervous system is that a Schwann cell only produces the myelin sheath for one segment of only one axon.
