1Glia are [blank_start]support[blank_end] for the nervous system. There are 4 types in the [blank_start]CNS[blank_end], and 1 type in the [blank_start]PNS[blank_end]. These types are highly specialised for [blank_start]different[blank_end] functions.
Neurons are cells specialised for [blank_start]transport[blank_end] of information. They can transmit [blank_start]many[blank_end] types of information, and there are [blank_start]thousands[blank_end] of types of neurons!- Asupport

3What is the role of microglia?
- ATo engulf microorganisms and debris, acting as immune cells for the neurons.
- BTo supply nutrients to cells and ensheath blood capillaries.
- CTo circulate the CSF.
- DTo support and ensheath neurons.
