Study Notes
Body Cavities and Serous Membranes
- Body cavities are lined by serous membranes, which cover the organs within them.
- In the abdominopelvic cavity, serous membranes are called parietal peritoneum (lining the cavity) and visceral peritoneum (lining the organs).
Types of Connective Tissue Proper
-
Dense Regular: Fibers arranged in parallel bundles, resists tension in one direction. Found in tendons and ligaments.
-
Dense Irregular: Fibers arranged in different planes, resists tension from multiple directions. Located in the fibrous capsules of joints and the dermis of the skin.
-
Elastic: Contains a high proportion of elastic fibers allowing for recoil after stretching; found in walls of large arteries.
-
Loose Connective Tissue:
- Areolar: Forms the lamina propria, supporting mucous membranes. Lines respiratory, gastrointestinal, and urogenital tracts.
- Adipose: Acts as a protective cushion, provides insulation, and stores energy.
- Reticular: Supports blood cells within lymphoid organs like lymph nodes and spleen.
Cartilage Composition
- Cartilage is classified as dense connective tissue with chondrocytes embedded in lacunae.
- Lacks nerve fibers and is avascular, composed of collagenous fibers and chondroitin sulfates.
Types of Cartilage
- Elastic Cartilage: Predominantly elastic fibers; provides flexible support such as in the external ear.
- Fibrocartilage: Tough and shock-absorbing; located between vertebrae.
- Hyaline Cartilage: Most abundant; serves as a supportive structure found in costal cartilages, nose, trachea, larynx, and joint padding.
Body Membranes
- Composed of epithelial tissue bound to connective tissue.
Mucous Membranes (Mucosa)
- Line cavities open to the exterior (e.g., respiratory, digestive, urinary, reproductive tracts).
- Contain goblet cells that produce mucus for protection and lubrication, sitting atop the lamina propria.
Serous Membranes
- Line closed body cavities, consist of mesothelium and underlying connective tissue.
- Secrete serous fluid to reduce friction between organs. Named based on their body cavity (e.g., pericardium, pleural, peritoneum).
Cutaneous Membrane (Skin)
- Covers body surfaces, the thickest and only dry membrane.
Synovial Membranes
- Line synovial joints and bursae, providing lubrication to reduce friction during movement.
Exocrine Glands Classifications
- Exocrine glands release products via ducts onto epithelial surfaces.
- Multicellular Exocrine Glands: Can be simple or compound based on the duct structure. They may vary in secretory part shapes: tubular, alveolar, or tubuloalveolar.
- Unicellular Glands: e.g., goblet cells; secrete mucus.
Types of Exocrine Gland Functions
- Merocrine: Secrete products via exocytosis while maintaining cell integrity.
- Holocrine: Release products when the entire cell ruptures, releasing both secretions and cell debris (e.g., sebaceous glands).
