Study Notes
Tissue Basics
- Tissues are organized groups of cells and intercellular substances with a common function.
- Four primary tissue types: epithelial, connective, muscle, and nervous tissue.
Epithelial Tissue
- Epithelial tissue has a basement membrane and exhibits polarity (free surface and basal surface).
- Simple squamous epithelium serves as the lining of serous membranes and provides a slick surface in cardiovascular organs (endothelium).
- Stratified squamous epithelium is characterized by cuboidal basal cells and flat keratinized surface cells.
- Transitional epithelium is found in areas that require stretching, like the urinary bladder.
- Simple columnar epithelium is equipped with dense microvilli, enhancing nutrient absorption.
Exocrine and Endocrine Glands
- Exocrine glands secrete substances onto surfaces (e.g., sweat glands) through ducts.
- Endocrine glands, such as the thyroid, secrete hormones directly into the bloodstream.
- Classification of multicellular exocrine glands includes merocrine, apocrine, and holocrine types.
Connective Tissue
- Connective tissues provide binding, support, insulation, and protection of organs.
- Components include ground substance, fibers (collagen for tensile strength), and cells.
- Chondroblasts in cartilage divide and secrete new matrix; fibrocartilage allows for shock absorption.
- Blood is categorized as a type of connective tissue.
Healing and Repair Processes
- Tissue repair involves an inflammatory stage (dilation of capillaries, white blood cell migration), followed by organization, granulation tissue formation, and regeneration.
- Scar tissue formation is indicative of fibrosis.
- Macrophages play a crucial role in cleaning debris from wounds, facilitating healing.
Characteristics of Specific Tissues
- Squamous cells are flattened in their mature form.
- Classifications of glandular epithelial cells include mucous cells as unicellular exocrine glands.
- Macrophages are found in areolar and lymphatic tissues and are significant in body's defense mechanisms.
Functionality of Various Tissues
- Most epithelial tissues have a regenerative capacity, while cardiac muscle and some nervous tissues lack this ability.
- The presence of microvilli on certain epithelial tissues increases surface area for absorption.
- Identifying the right type of epithelium is essential for understanding its specific role in the body.
Additional Notes
- Tissues' specific structures correlate directly to their functions (e.g., ciliated epithelium aids in movement of mucus).
- The sequence of events in tissue repair is vital for understanding healing timelines and processes.
