Study Notes
Introduction to Pathology
- Pathology laboratory sections are managed by a section head or laboratory manager.
- Surgical pathology is a division of histopathology.
Key Personnel in Pathology
- Pathologist: An expert performing gross examinations in surgical pathology.
- Histotechnician: Entry-level term for medical technologists in histopathology.
- Histotechnologist: More advanced role in the U.S., focused on tissue processing and laboratory tasks.
Role of Medical Technologist
- Involves examining tissues to detect diseases through routine processing.
- Immunohistochemistry staining is utilized for specific diagnostic information.
Fundamentals of Histology
- Histology: Study of tissues (from the Greek “histo” for tissue).
- Histopathology: Study of tissue abnormalities, integrating histology and pathology.
Normal Cell Structure
- Cells are dynamic structures existing in a fluid environment.
- Basic unit of tissues; structure is directly linked to function.
Cell Membrane Composition
- Composed of phospholipids, glycolipids, cholesterol, proteins, and carbohydrates.
- Functions in cell communication through receptors (glycocalyx) and proteins recognizing antigens.
- Microfilaments contribute to cell structure; microvilli enhance absorptive capabilities.
Functions of Cell Membrane
- Selective Permeability: Controls transport of substances into and out of the cell.
- Mechanisms include diffusion, sodium pumps, and pinocytosis, maintaining internal regulation.
Cytosol and Organelles
- Cytosol: Gel-like substance surrounding organelles.
- Lysosomes: Vacuoles containing enzymes for digestion and waste processing.
- Organelles are involved in protein processing and transport, including post-translational modifications.
