Schwan cells
The fatty tissue that covers axons and speeds up impulses is called myelin. Myelin acts as an insulating layer, which helps to increase the speed and efficiency of nerve impulse transmission along the axon.
Schwann cels make the myelin shealth that facilitate with neuron message transport
cell
A schwann cell are supporting cells of the peripheral nervous system, they wrap themselves around nerve axons.
Remember: Axons away, so dendrites carry messages from the cell, and axons carry them away.
cell
Neurons, of the nervous system. The dendrites receive impulses, and the axons send them to another neuron or an effector cell.
Oligodendrocyte
No, axons carry impulses away from the nerve cell body.
Oligodendrocytes are a type of glial (supporting) cell in the brain that sends out cytoplasmic extensions to insulate axons in the central nervous system. This allows for greater speeds of nervous impulses between the brain and a sensory receptor or between two neurons ("brain" cells).
