schwann 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.
Schwann cells are glia that myelinate the neurons of the Peripheral Nervous System
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,
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.
