Study Notes
Pathology Definition
- Pathology is the study of disease and the bridge between science and medicine.
- Pathophysiology focuses on functional changes in the body related to disease.
Subdivisions of Pathology
- Anatomical Pathology: Diagnoses diseases through gross, microscopic, and molecular analyses of tissues and organs. Includes biopsies, surgical procedures, cytology, and autopsies.
- Clinical Pathology: Diagnoses diseases through laboratory analysis of bodily fluids and tissues.
- Other subdivisions include dermatopathology, forensic pathology, hematopathology, histopathology, molecular pathology, and surgical pathology.
Cytopathology
- Studies and diagnoses diseases at the cellular level.
- Aids in the diagnosis of cancer, infectious diseases, and inflammatory conditions.
Histopathology
- Microscopic examination of human tissues.
- Tissues are examined after surgery, biopsy, or autopsy.
Disease
- Any harmful deviation from the normal structure or function of an organism.
- Examples include infection, poisoning, nutritional deficiencies, toxicity, and environmental factors.
Infection
- Invasion of tissues by pathogens like bacteria, viruses, and fungi.
- Involves pathogen multiplication and host tissue reactions to the pathogen and its toxins.
- Infectious diseases can be viral, bacterial, parasitic, or fungal.
Inflammation
- Protective response to harmful stimuli such as pathogens, damaged cells, or irritants.
- Aims to eliminate the cause of injury, clear out dead cells, and repair damaged tissues.
Tests
- Medical diagnostic tests include biopsies, blood analysis, dissection, and medical microscopy.
Biopsy
- "Bio" meaning living and "psy" meaning study.
- Study of living tissue samples.
Necropsy
- "Necro" meaning dead and "psy" meaning study.
- Study of a dead animal.
Autopsy
- Technically a necropsy performed on a human.
Pathologist
- Medical doctor with specialized training to diagnose medical conditions using laboratory tests and techniques.
Glossary
- List of definitions related to medicine and its sub-disciplines.
- Useful for understanding medical terms in different countries and contexts.
Cell Death
- Eliminates potentially harmful cells.
- Three major types:
Apoptosis
- Regulated, programmed process of eliminating unwanted cells.
- A physiological process that avoids inflammation.
Autophagic Cell Death
- Process of reusing old and damaged cell parts.
- Removes unnecessary or dysfunctional components through lysosomes.
Necrosis
- Pathological process caused by external agents like toxins, trauma, and infections.
- Unregulated, random process that elicits inflammation.
Types of Necrosis in Pathophysiology
- Liquefactive Necrosis
- Coagulative Necrosis
- Caseous Necrosis
- Fat Necrosis
- Fibrinoid Necrosis
- Gangrenous Necrosis
