Study Notes
Loose Connective Tissue Proper
- Predominant cell type is fibroblasts, which produce fibers and ground substance.
- Loose connective tissue features a flexible and irregular arrangement of fibers, aiding in support and elasticity.
Adipose Tissue
- Commonly found in subcutaneous regions, around organs, and in bone marrow.
- Primary function is energy storage, providing insulation and protection to organs.
- Also helps in thermoregulation and cushioning against mechanical shocks.
- Predominant cell type is adipocytes, specialized for fat storage.
Areolar Tissue
- Characterized by a loose arrangement of fibers and abundant ground substance.
- Commonly located beneath epithelial tissues and surrounding organs.
- Functionally supports and binds tissues together while allowing for flexibility.
Reticular Tissue
- Composition includes a network of thin, branching reticular fibers made of collagen.
- Commonly found in lymphoid organs such as lymph nodes and the spleen.
- Primary function is to provide a supportive framework for organs.
Dense Connective Tissue
- Dense regular connective tissue is found in tendons and ligaments, providing strong attachment points.
- Dense irregular connective tissue features collagen fibers arranged in various directions, offering strength against multidirectional forces.
- Elastic connective tissue consists primarily of elastic fibers, enabling stretch and flexibility, commonly found in large arteries and lung tissue.
Specialized Connective Tissue
- Three types include cartilage, bone, and blood.
- Cartilage is typically found in joints, the ribcage, and the nose.
- Primary cell type in cartilage is chondrocytes, which maintain the extracellular matrix.
- Cartilage’s resilient quality is due to its high water content and presence of proteoglycans.
Hyaline Cartilage
- Commonly found in the trachea, larynx, and articular surfaces of joints.
- Characterized by a smooth matrix which facilitates frictionless movement.
- Surrounded by perichondrium, providing nutrients and support.
- Primary function is to reduce friction and absorb shock at joints.
Elastic and Fibrocartilage
- Elastic cartilage is found in structures requiring flexibility, such as the ear and epiglottis.
- Distinguished by a dense network of elastic fibers, allowing it to return to shape after deformation.
- Fibrocartilage is located in intervertebral discs and the pubic symphysis, providing strength and shock absorption due to its dense collagen fiber composition.
Bone Tissue
- Hardness and rigidity are due to hydroxyapatite crystals, primarily calcium phosphate.
- Well vascularized, allowing for efficient nutrient distribution and bone remodeling.
- Main composition includes an organic matrix (collagen) and mineral components (calcium and phosphorus).
Blood
- Thrombocytes are also known as platelets, essential for blood clotting.
- Red blood cells (erythrocytes) are responsible for oxygen transport throughout the body.
- Fibers are primarily needed during clot formation to stabilize the blood clot.
- White blood cells (leukocytes) are crucial for immune response, providing defense against pathogens.
