Myelination animation
This simple animation shows how during development a glial cell myelinates a neural axon.
- Grey - axon
- Brown - glia cytoplasm
- Blue - glia nucleus
- Black - glia cell membrane, forming myelin sheath.
- mesaxon - site of glial membrane initial contact.
Myelination process
- Peripheral glial cell - Schwann cell.
- Central glial cell - Oligodendrocyte.
- leads to an increased conduction velocity within the axon that is myelinated compared to an unmyelinated axon.
- occurs late in neural development in both the central and peripheral nervous system.
- begins in third trimester and continues postnatally. (More? Neural development overview table)
- glia develop (later) from the same stem cell population as neurons.
