Study Notes
Body Cavities and Serous Membranes
- Serous membranes line body cavities and cover organs, reducing friction between moving organs.
- In the abdominopelvic cavity, serosa is categorized into parietal peritoneum (lining cavity) and visceral peritoneum (covering organs).
Exocrine Glands Structure and Function
- Exocrine glands release substances via ducts to epithelial surfaces.
- Classified on structural basis: unicellular (e.g., goblet cells) and multicellular glands (simple or compound).
- Multicellular glands can be tubular, alveolar, or tubuloalveolar.
- Functionally classified into merocrine (secrete via exocytosis) or holocrine (rupture to release secretion).
Types of Connective Tissue Proper
- Dense Regular: Fibers arranged in parallel bundles, resists tension, found in tendons and ligaments.
- Dense Irregular: Fibers packed in different planes, capable of withstanding tension from multiple directions, located in the dermis and fibrous capsules of joints.
- Elastic: Contains high elastic fiber content, allows recoil after stretching, found in walls of large arteries.
Loose Connective Tissue
- Areolar Tissue: Forms lamina propria in mucous membranes, supports organs and contains blood vessels.
- Adipose Tissue: Provides insulation and protects tissues, stores energy, characterized by a "bubble-like" appearance with little matrix.
- Reticular Tissue: Supports blood cells in lymphoid organs like lymph nodes, bone marrow, and spleen.
Composition and Types of Skeletal Cartilage
- Cartilage is dense connective tissue, composed of chondrocytes within lacunae embedded in a matrix.
- Lacks blood vessels (avascular) and does not contain nerve fibers.
Types of Cartilage in the Skeletal System
- Elastic Cartilage: Contains elastic fibers, providing flexibility; found in the external ear.
- Fibrocartilage: Tough and shock-absorbing; located between vertebrae.
- Hyaline Cartilage: Most abundant, provides support and padding, present in costal cartilages of ribs, nose, trachea, and joints.
Membranes in the Body
- Mucous Membranes (Mucosa): Line cavities open to the exterior (e.g., respiratory, digestive, urinary tracts). Contain goblet cells that produce mucus for protection and lubrication.
- Serous Membranes: Line closed body cavities and consist of a single layer of mesothelium over connective tissue. Secrete serous fluid for lubrication; examples include pericardium, pleural, and peritoneum.
- Cutaneous Membrane: The skin, thickest membrane, and is the only dry membrane.
- Synovial Membranes: Line the inner surfaces of joints, secrete synovial fluid for lubrication, reducing friction during movement, and cushioning impacts on bones.
