Nerve fibres of brain (Quick question)

[sameeralord]

Hello everyone,

I know nerve fibres inside brain are not covered by perineurium etc like Peripheral nervous system. Are they still covered with connective tissue, support cells, myelin etc. I mean inside the brain , a collection of nerve fibres, how are they held together with no connective tissue. I don't have much knowledge about brain. Thanks

myelin

It is there, although not from the beginning. At least in human brain.

It is there

Not for all fibers. For most, though.

There is a lot more in the brain than just nerve cells, if that's what you're getting at. Immune cells, vascular cells, extracellular matrix, ...
