No, in the PNS, or peripheral nervous system.
In this case it is satellite cell. In the PNS system there are only two types of cells which are in the neural structures outside the CNS, Schwann Cells and Satellite cells. The Satellite cells surround neuron cell bodies in ganglia.
Satellite cells are only found in the peripheral nervous system (PNS). These cells provide support and nutrients to the neurons in the PNS.
Theodor Schwann was the scientist who determined that all animals were made out of cells.
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.
Scheliden and Schwann
Matthias Schleiden, Theodor Schwann, and Rudolf Virchow were pioneers in the study of cells. Schleiden and Schwann formulated the cell theory, stating that all living organisms are composed of cells, while Virchow proposed that cells can only arise from pre-existing cells.
1) starting with the obvious; oligodendrocytes myelinate axons in the CNS whereas schwann cells myelinate axons in the PNS 2) a single oligodendrocyte is able to myelinate multiple axons whereas a schwann cell can only myelinate a single axon. 3) schwann cell myelination allows for axonal grown and regeneration where as oligodendrocytes inhibit axonal growth and regeneration. 4).... and probably a bunch more differences
The cell theory is credited to Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden and Schwann proposed that all living organisms are composed of cells, while Virchow added that cells only arise from pre-existing cells.
Theodor Schwann and Matthias Schleiden are credited with proposing the cell theory in the 19th century, which states that all living organisms are composed of cells. Rudolf Virchow later added to this theory by stating that cells only arise from pre-existing cells.
A+ Students - myelin sheath A Schwann cell is a particular type of neuroglial cell, found only in the peripheral nervous system. Schwann cells produce the myelin sheath, which insulates the axons of bodily nerves, increasing the signal velocity.
Schleiden and Schwann came up with what is known as "The Theory of Cells" or "Cell Theory." The main principles of "Cell Theory" are: 1. All living things are made up of cells. 2. Cells are the smallest units of living things 3. Cells only rise from existing cells. Schleiden said that All plants are made up of many different kinds of cells. Schwann added to that and said that All animal are made up of many different kinds of cells. Schwann also said that growth and development is due to the division of cells.
Chloroplasts are only found in plant cells.
