A
-cytoplasmic projections (dendrites, single axon)
-soma, dendrites, proximal part of the axon
(CNS) parts of oligodendrocyte
(PNS) part of a Schwann cell

Q
What are the 4 types of neurone?
A
Motor (CNS to periphery, send signals to effector tissues)
Sensory (Periphery towards CNS, send environmental signals to integrative centre)
Integrative (CNS, collate all the info)
Anaxonic (retina, act as relays)
