Study Notes
Overview of Connective Tissue
- Connective tissue supports body structure and organs, providing cohesion and internal stability.
- Varies in density, cellularity, and specialization among types.
Components of Connective Tissue
- Composed of water, cells (e.g., fibroblasts, adipocytes, macrophages), and an extracellular matrix.
- Extracellular matrix consists of glycoproteins, fibrous proteins, and glycosaminoglycans (GAGs).
Cells of Connective Tissue
- Fixed cells include:
- Fibroblasts
- Adipocytes
- Macrophages
- Mast cells
- Transient cells include:
- Plasma cells
- Eosinophils
Extracellular Matrix
- Known as ground substance; an amorphous, gelatinous, and transparent material.
- Fills spaces between cells and fibers, facilitating transportation of metabolites.
- Composed of GAGs that form proteoglycans, which help resist compression.
Types of Fibers
- Fibers secreted by fibroblasts create a supporting network for cells.
- Three main types of fibers:
- Elastic fibers
- Collagen fibers
- Reticular fibers
Classification of Connective Tissue
- Connective Tissue Proper:
- Loose connective tissue
- Dense connective tissue (regular and irregular)
- Specialized Connective Tissue:
- Supporting connective tissue (cartilage, bone)
- Fluid connective tissue (blood, lymph)
Loose Connective Tissue
- Contains numerous cells and loose fibers, aiding in support and connection of other tissues.
- Types include:
- Areolar: Covers muscle fibers, present in skin and mucous membranes.
- Adipose: Acts as insulation and energy store, comprises white adipose tissue.
- Reticular: Contains reticular cells, found in lymph nodes.
Dense Connective Tissue
- Characterized by thick fibers and a slightly viscous fluid.
- Types include:
- Dense Regular: Fibers arranged parallel for strength.
- Dense Irregular: Fibers arranged randomly for multi-directional strength.
Specialized Connective Tissues
- Cartilage:
- Coarser than other connective tissues, populated with chondrocytes.
- Types include hyaline, fibrocartilage, and elastic cartilage.
- Bone:
- Divided into compact and spongy bone types.
Blood
- Composed of plasma, a specialized fluid, with circulating blood cells (erythrocytes, leucocytes, platelets).
Learning Outcomes
- Ability to state functions and characteristics of connective tissue.
- Knowledge of non-cellular substrates, cell types, and fiber classifications in connective tissue.
- Understanding of connective tissue types and their organization in the human body.
