What are the types of glial cells present in the central nervous system and their functions?
I - Oligodendrocytes are contained in axonal myelin sheaths.
II - Microglia represents the immune cells in the nervous system.
III - Ependymal cells are located in ventricular zones, performing barriers, and provide stem cells.
IV - Astrocytes participate in neuronal energy support by capturing ions, water, glucose, and regulating neurochemical actions in synaptic clefts, recapturing neurotransmitters.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only III and IV are correct.
d) All statements are correct.

A resposta correta é a alternativa d) Todas as afirmações estão corretas. I - Oligodendrócitos estão contidos nas bainhas de mielina axonal. II - Microglia representa as células imunes no sistema nervoso. III - Células ependimárias estão localizadas em zonas ventriculares, realizando barreiras e fornecendo células-tronco. IV - Astrócitos participam do suporte energético neuronal capturando íons, água, glicose e regulando ações neuroquímicas nas fendas sinápticas, recapturando neurotransmissores.
