The cells in the nervous system are eukaryotic as they have a cytoskeleton that consists of network of filaments and a nucleus that contains DNA and organelles that help the cell survive and reproduce. The key organelles are nucleus with nucleolus, nuclear membrane, mitochondria, centrosome that helps in cell division and formation of microtubules, and Golgi apparatus that forms the lysosomes that remove waste and recycles materials. The cytoplasm of the cell contains the organelles and filaments that maintain the cell structure.
