3:27 not 50 times 🙄😱 But make up just more than 50% of the nervous tissues. But some sources say excitable (neurons) and nonexcitable(neuroglia) cells contribute to nervous system formation in the ratio of 1:1. BTW (For ur information) some people also say that neuroglia are made of of connective tissue(and not neural),working in coordination with the neurons: repair,healing,nursing,nourishment, myelin sheath formation,BBB,etc. But they are weirdly derived from the ectoderm (except for microglia, which are derived from mesoderm).
