Study Notes
Connective Tissue Overview
- Connective tissue (CT) is one of the four basic tissue types, consisting of cells and an extracellular matrix (ECM).
- ECM is composed of structural fibers and specialized proteins that form the ground substance.
- CT provides structural support, mechanical support, and mediates nutrient and waste exchange.
Macrophages
- Macrophages are phagocytic cells derived from monocytes and contain lysosomes.
- They play a crucial role in the immune system.
Types of Connective Tissue Cells
- Fibroblasts: Most common CT cell type; synthesize collagen and other fibers; metabolically active.
- Mast Cells: Large cells that release histamine and heparin; important in inflammatory responses.
- Adipocytes: Fat-storing cells that can be white (less active) or brown (thermogenic, found mainly in infants).
- Leukocytes: White blood cells, including lymphocytes (adaptive immunity), neutrophils (inflammation), and plasma cells (antibody production).
Connective Tissue Fibers
- Composed of proteins produced by fibroblasts and categorized into:
- Collagen Fibers: Provide tensile strength, the most abundant protein in mammals (25% of total protein mass), appear wavy under microscopy.
- Elastic Fibers: Allow for stretch and distension; thinner than collagen and arranged in a branching, three-dimensional network.
- Reticular Fibers: Comprised of type III collagen, create a supportive framework particularly in lymphatic tissues.
Classification of Connective Tissue
- Connective Tissue Proper: Includes loose and dense connective tissue.
- Supportive/Specialized Connective Tissue: Comprises cartilage and bone.
- Fluid Connective Tissue: Comprises blood and lymph.
Types of Connective Tissue
- Loose Connective Tissue: Found near epithelia, contains various fibers and cells; site for inflammatory responses; types include areolar, adipose, and reticular.
- Dense Connective Tissue: Offers strength; types include regular (tendons, ligaments) and irregular (providing multidirectional strength).
Specialized Connective Tissues
- Mucous Connective Tissue: Primitive and found in the umbilical cord, composed of spindle-shaped fibroblast-like cells.
Functions and Locations
- Loose Areolar Tissue: Supports and surrounds organs, contains a mix of fibers and cells; important for immune reactions.
- Adipose Tissue: Specialized for fat storage and insulation; white adipose tissue stores energy while brown adipose tissue generates heat.
- Reticular Connective Tissue: Provides structure to soft organs like the spleen and liver.
- Dense Regular Tissue: Arranged in parallel for maximum strength, found in tendons and ligaments.
Summary
- Connective tissue is essential for structural integrity and functions in supporting other tissues, immune responses, and nutrient exchange.
- Different cells and fibers within CT determine its specialized properties and functions.
