Normal cytologic structure of the major tissue types in various species will be studied. Abnormal changes will then be identified and studied, and pathophysiologic causes of these abnormalities discussed. Cytologic changes will be related to gross anatomical appearance and abnormalities that would be evident on diagnostic imaging modalities. Students will gain understanding of the symptoms created in the patient by the diseased tissue and which diseases/disorders must therefore be considered. The required laboratory will provide students with the skills utilized in histological preparations and examination of normal and diseased tissue.
