In the peripheral nervous system otherwise known as the PNS.
satellite cells and schwann cells
No, in the PNS, or peripheral nervous system.
myelin sheath
Schwann cells are functionally similar to oligodendrocytes in the central nervous system. They both provide support and insulation to nerve fibers by forming a myelin sheath around them, which helps in the transmission of nerve signals. Schwann cells are found in the peripheral nervous system while oligodendrocytes are found in the central nervous system.
No, Schwann cells do not surround axons of neurons in the cerebrum. Schwann cells are primarily found in the peripheral nervous system, where they myelinate peripheral axons. In the central nervous system, including the cerebrum, oligodendrocytes perform a similar function by myelinating axons.
Schwann cells and oligodendrocytes
This questions has been answered below in the related discussions, "what are Schwann cells"
schwann cells
The specialized cells that myelinate the fibers of neurons in the peripheral nervous system are called Schwann cells. Schwann cells wrap around the axons of neurons to form the myelin sheath, which helps to insulate and protect the nerve fibers, allowing for faster and more efficient conduction of nerve impulses.
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
As there are nerve cells in stomach linings, one would assume so. Schwann cells are glial cells that protect and help neurons and are found in the peripheral nervous system--all nerves outside the brain and spine. So although I've never studied a dogs stomach, it seems impossible for them not to have them. Axons need the insulation provided by the schwann cells to properly function.
The Remaining Schwann Cells schwann cells, after injury and disruption to target, the remaining schwann cells undergo a rapid mitotic division until the target tissue is reached and the successful pathway is regenerated under the structural guidance of the schwann cells,
