Answer: neuroglial cells; since neuroglial cells are capable of mitosis
Complete question: “Neurons are amitotic, which means that, after a certain stage, they do not divide further. Most tumor cells are characterized by a rapid rate of mitosis. Based on this, of which cell types brain tumors be composed (neurons or neuroglia)? Why”
Brain tumors are composed of neuroglia, the non-neuronal cells in the central nervous system that maintains homeostasis, form myelin, provide support and protection for neurons and capable of mitosis.
