Schizophrenia & Huntington's Chorea
Microscopic pathology has been reported in a variety of diseases including schizophrenia, Huntington's chorea, Alzheimer's disease, Parkinson's disease, etc. Alzheimer's disease is discussed on a separate page in this website. Reports in schizophrenia have included chromatolysis, pyknosis, gliosis (Stevens, 1982, Nieto & Escobar, 1972, and many others), neuron loss, mineralization, lipoid accumulation, ependymal granulations, corpora amylacea, etc. Gliosis is seen in Huntington's chorea.

This clipart of a drawing by Warren Lewis is so old that it uses the notation of a century ago. The "axis cylinder" is now called the "axon". These are myelinated nerve fibers shown in a transverse section. The term "medullary" has been replaced by "myelinated".
This clipart is color version of an animal cell. It is from the emc website which is an educational institution site. I have not yet thoroughly explored this site, but I will try to do so in the future because it appears extremely valuable. At that time I will comment further on this site.
More organelles are shown in this clipart from Cells, which is a site in the High School Hub network. The flagellum is of interest mostly in microorganisms. It is like a hair which helps the cell move. Sperm cells have this to assist their movement. It is of no interest in the central nervous system.
This clipart of a motor neuron comes from High School Hub.
This clipart of an electron micrograph showing happy mitochondria comes from High School Hub.
This clipart of the Golgi apparatus comes from a site called "High School Hub", which is really a cluster of different sites woven together into a network with links.
This clipart is from the Users website, which is part of the High School Hub network. It shows the cell membrane.
Shown here is the Dutch scientist Antony van Leeuwenhoek, who invented the microscope. The clipart is from a Berkeley site which is part of High School Hub. Later on Robert Hooke of England published brilliant observations with the use of the compound microscope, now called the "light" microscope. In the 20th century the electron microscope was invented.
This clipart is from the EMC website, which is part of the High School Hub network. It shows the types of cells found in the stomach.
