Is the schwann cell a plant cell?
No--a schwann cell is a type of glial cell, a cell that functions to help and support neurons in a nervous system.
Contributions of schleiden and schwann?
The cell theory
What scientist did not make a contribution to cell theory?
Schwann
Who advanced the cell theory with his conclusion that cells could only come from cells?
Schliden, Schwann, and Virchow.
Funtion of the nucleus of a schwann cell?
When the peripheral nervous system develops, Schwann cells line up along unmyelinated axons at regular intervals that eventually become the nodes of Ranvier (important for saltatory nerve condution). The ensheathing process takes place as Schwann cells wrap around the axon many times over, creating concentric layers whose cytoplasm progressively condenses. Contact with the axons also activates myelin genes leading to the expression of myelin glycoproteins and lipids across the Schwann cell plasma membrane. The sheath therefore consists of plasma membrane, cytosol, lipids, glycoproteins, and the Schwann cell nucleus.*So basically, the schwann cells is a protective membrane that covers the axon. It also produces myelin sheath (the coating of a neuron), which increases the speed of the nerve impulse.
What is another name for the sheath of schwann?
another name for the sheath of schwann is neurilemma.
What did virchowschleidan and schwann each contribute to the cell theory?
The name of the theory that Schleiden and Schwann developed is the cell theory.
Is the schwann cell a plant cell?
No--a schwann cell is a type of glial cell, a cell that functions to help and support neurons in a nervous system.
The sheath of Schwann is also called what?
Its the Neurilemma.
Who studied plant cell?
Schwann
Who was Schwann?
The German biologist Theodor Schwann (1810-1882) is considered a founder of the cell theory.
What is a schwann cell?
A schwann cell are supporting cells of the peripheral nervous system, they wrap themselves around nerve axons.
How many axons can a single Schwann cell myelinate?
Unlike oligodendrocytes Schwann cells can only myelinate one axon. But the number of Schwann cells it takes to myelinate an axon depends on the axon length as a Schwann cell only myelinates one area between pairs of Nodes of Ranvier. Think of it like a string of sausage. the sting is the axon, each sausage is where a single Schwann cell myelinates that axon, as stated the length will determine the total number of Schwann cells needed for myelination, but a Schwann cell can only myelinate one axon.
Did Theodor Schwann work alone to develop the cell theory.?
False
Who is Theodore schwann and what did he do?
The German biologist Theodor Schwann (1810-1882) is considered a founder of the cell theory.
