The human nervous system performs greatly varied and highly complex functions: It oversees the functions of all bodily organs; it receives and integrates information from all senses; it initiates and coordinates motor activities; and notably, it processes our thoughts, generates our emotions, and stores our memories. Billions of cells are organized, categorized, and specialized to carry out these functions. The neurons are the executives, the glial cells provide adequate environment, the blood vessels furnish nutrients, and the meninges protect from injuries. The neurons, glial cells, blood vessels, and meninges each has a distinct morphology and displays characteristic changes in diseases.

This chapter presents the characteristic reactions of neural tissue to diseases, along with a brief description of their normal histology, and the pathologic conditions particular to the nervous system.
