Study Notes
Key Concepts of Tissues
- Tissue: A group or layer of similar cells that perform specific functions.
- Histology: The microscopic study of tissues, focusing on structure and function.
- Histologist: A specialist in histology, not a physician.
Types of Tissues
- Epithelial Tissue: Protective covering for internal and external surfaces; forms glands.
- Epithelium: Specialized epithelial tissue forming the skin's epidermis and mucous membranes.
- Endothelium: Epithelial tissue lining blood vessels, lymphatic vessels, body cavities, and organs.
Connective Tissue
- Provides support and connection for organs and tissues; includes:
- Dense Connective Tissue: Comprises bone and cartilage, forming joints and body framework.
- Adipose Tissue: Fat tissue that provides padding, insulation, and support.
- Loose Connective Tissue: Surrounds organs and supports nerve cells and blood vessels.
- Liquid Connective Tissue: Includes blood and lymph, responsible for nutrient and waste transport.
Muscle and Nerve Tissue
- Muscle Tissue: Contains cells specialized for contraction and relaxation.
- Nerve Tissue: Contains cells that respond to stimuli and conduct electrical impulses.
Pathology of Tissue Formation
- Disorders that affect tissues, categorized into:
- Incomplete Tissue Formation: Conditions like Aplasia (absence of tissue) and Hypoplasia (underdevelopment due to insufficient cells).
- Abnormal Tissue Formation: Includes Anaplasia (structural cell changes), Dysplasia (abnormal growth), Hyperplasia (tissue enlargement due to increased cells), and Hypertrophy (increase in size, not number, of cells).
Definitions for Pathological Conditions
- Aplasia: Congenital absence or defective development of an organ or tissue.
- Hypoplasia: Incomplete development due to cell deficiency.
- Anaplasia: Structural changes in cells and their orientation.
- Dysplasia: Abnormal growth of cells, tissues, or organs.
- Hyperplasia: Organ or tissue enlargement from excessive cell increase.
- Hypertrophy: Increase in size of a body part due to cell size enlargement.
