Sir William Osler. Professor of Medicine at Johns Hopkins University School of Medicine. Known for his compassionate bedside manner, and academic prowess, he is considered The Father of Internal Medicine. Dr. Osler is also the inventor of the classic internship and residency we use to train medical graduates in the United States.Atypical Pneumonia


Welcome to the Pathology Reference. This is an undergraduate level reference.

The study of Human Pathology, like Human Anatomy, is one of the pillars to a strong foundation in Medicine and its related Allied Health Disciplines.

Pathology is the study of disease and its processes. Studied in a precise technique, it is always an investigative science, exploring evidence based etiology, mechanisms of disease development (pathogenesis), structural alterations of cells and their biochemical processes (morphological changes), and the consequences of these changes (clinical manifestations).

The Conservatory teaches and tutors Pathology for students in Colorado Springs year-round, and offers an online course. This tool allows us to present this subject as an online textbook and learning module, available at no cost to our students. This is not only available as an assistant to the students we teach on campus, but is available to anyone wanting to increase their medical knowledge and competitive edge.

For you to be able to utilize our online course at no cost, you must sign into The Guest Book, and request this course. We will then add you to our roster and email access codes to you. Keep in mind that this is a large and concise text on the introduction to Pathology, with evidence based didactics, case studies, illustrations, web-links, and practice tests.

The Pathology Reference is an introduction to Anatomic and Clinical Pathology. Below you will find our visual library with accompanying didactic discussions. The images and illustrations are arranged in a systems blended format. You may point and click to enlarge.

When any image is enlarged, you may move through the image library as a slide presentation. By using the blue arrows, you may advance and reverse in stop mode. By utilizing the white play button, you may pause to review and peruse as long as you prefer. When in play mode, the image bank is presented as a moving slide show.

Beginning with a short introduction, as well as Structure and Function, the library then moves into Biochemistry; Cells and Tissues; then Organ Systems and Mechanisms of Disease.

From here you will move through all body systems in this order: The Integument; The Musculoskeletal System; The Central and Peripheral Nervous System; The Endocrine System; Blood and the Cardiovascular System; Lymphatics and the Respiratory System; Digestion, Nutrition, and Metabolism; Fluid, Electrolytes, and Acid-Base Physiology; followed by Reproduction, Growth and Development; and finally, Genetics.

Additional online help is available at, and The Journal of Clinical Pathology. There are also recommended textbooks available in our Bookstore.
