| Abstract: | Theodor Schwann, the German physiologist who first propounded the cell theory with M Schieiden, had diverse interests. He
was not only the first to isolate the enzyme pepsin, but also investigated muscle contraction and nerve structure. In the
mid nineteenth century Schwann discovered that a sheath made up of myelin covered the axons of neurons in the peripheral nervous
system (PNS). The cells that form the myelin are today called Schwann cells after him. Today, we know that the Schwann cells
not only form the myelin sheath around neurons, but also regulate several neuronal functions and are an indispensable part
of the PNS. |
