Study Notes
Chromosomal Abnormalities
- Genetic mutations can lead to various chromosomal abnormalities that affect cell function and development.
Nutritional Imbalances
- Nutritional status can significantly affect cellular health, including both deficiencies and excesses.
Cellular Adaptation
- Cells can adapt to stress through several processes, moving from a normal state towards injury.
- Hyperplasia occurs when cells capable of DNA synthesis increase in number.
Types of Hyperplasia
- Physiologic Hyperplasia
- Hormonal: Examples include breast development during puberty and uterine changes in pregnancy.
- Compensatory: E.g., liver regeneration after resection or injury.
Dysplasia
- Characterized by disordered cellular development, primarily affecting epithelial tissues.
- Involves cellular pleomorphism, with variations in cell size and shape, as well as nuclear irregularities.
Benign Neoplasms
- Chondroma: A benign tumor that develops in cartilage tissue.
- Hemangioma: A benign tumor formed from blood vessel proliferation.
- Lipoma: The most common benign fatty tumor, typically located just beneath the skin.
Pathways of Tumor Spread
- Lymphatic Spread: Tumor cells spread through the lymphatic system.
- Hematogenous Spread: Tumor cells disseminate via the bloodstream.
- Seeding of Body Cavities: Tumor cells can invade pleural, peritoneal cavities, and cerebral ventricles.
