Schwann cells have at least two functions. They have much fat in them and they act as an insulator. Much like the covering on the cords you have in your home. It prevents short circuits. (Think what would happen to you if the cord you are plugging had no covering). The other function is the space between the cells on the axon (cord). This allows the impulse to jump from space to space and the impulse is more rapid with schwann cells.
Shwann Cells-PNS Oligodendrocytes-CNS Both form the neurolemma
Schleiden & Shwann
The cell theory was proposed by Matthias Schleiden, Theodor Schwann, and Rudolf Virchow in the 19th century. They observed that all living organisms are composed of cells and that cells are the basic unit of structure and function in living things.
ativated B cells forms effector cells which are called plasma cells
blood cells, white blood cells, sperm cells, brain cells.
Theodore Shwann was a physiologist from Germany. He discovered Schwann cells, yeast, and pepsin. He also was the person who started the word, metabolism.
Theodore Schwann concluded that animals are also made out of cells.

The three contributers to cell theory are Shliden, Shwann, and Virchow.
Theodor Schwann was a German physiologist and histologist who is best known for his contributions to cell theory. He studied the structure of animal tissues and discovered that all living organisms are composed of cells, which led to the formulation of the idea that cells are the basic unit of life. Schwann also identified Schwann cells, which are responsible for the myelination of nerve fibers in the peripheral nervous system. His work laid the foundation for understanding the cellular basis of biology and the organization of tissues.

The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes nerves outside of the CNS. The CNS acts as the main control center, while the PNS connects the CNS to the rest of the body.
Some examples of plant cells are : Parenchyma Cells, Collenchyma Cells, Sclerenchyma Cells, and water conducting cells. Animal cells are nerve cells, muscle cells, and skin cells.
