Study Notes

Overview of Connective Tissue

  • Connective tissue maintains the body's form and provides cohesion and internal support.
  • Characteristics include density, cellularity, and specialization.

Essential Functions and Components

  • Composed of water, cells, and extracellular matrix (ECM).
  • Cells include fibroblasts, adipocytes, macrophages, mast cells, plasma cells, and eosinophils.
  • ECM contains glycoproteins, fibrous proteins, and glycosaminoglycans (GAGs).

Connective Tissue Cells

  • Fixed cells include:
    • Fibroblasts (produce fibers and matrix)
    • Adipocytes (store fat)
    • Macrophages (immune response)
    • Mast cells (inflammatory response)
  • Transient cells include:
    • Plasma cells (produce antibodies)
    • Eosinophils (immune function)

Extracellular Matrix

  • Known as ground substance, it's a gelatinous, transparent material that fills spaces between cells and fibers.
  • Composed of GAGs and proteoglycans, providing resistance to compressive forces.

Fibers of Connective Tissue

  • Secreted by fibroblasts; provide structural support.
  • Three main types:
    • Elastic fibers (stretch and recoil)
    • Collagen fibers (strength and support)
    • Reticular fibers (framework for organs)

Classification of Connective Tissue

  • Divided into:
    • Connective Tissue Proper:
      • Loose Connective Tissue (Areolar, Adipose, Reticular)
      • Dense Connective Tissue (Regular, Irregular, Elastic)
    • Specialized Connective Tissue:
      • Supporting (Cartilage, Bone)
      • Fluid (Blood, Lymph)

Types of Loose Connective Tissue

  • Areolar: Supports and connects other tissues, found in most areas of the body.
  • Adipose: Stores energy and insulates body; consists of white and brown adipose tissue.
  • Reticular: Contains reticular cells; found in lymph nodes and organs.

Dense Connective Tissue

  • Dense Regular: Parallel collagen fibers, strong in one direction.
  • Dense Irregular: Collagen fibers arranged unpredictably, provides strength in multiple directions.

Specialized Connective Tissues

  • Cartilage: Firm matrix comprised of chondrocytes and fibers; types include Hyaline, Fibrocartilage, and Elastic.
  • Bone: Composed of compact and spongy types; provides structural support.
  • Blood: Highly specialized fluid connective tissue with plasma and cells (erythrocytes, leucocytes, platelets).

Functions in Dental Therapy

  • Understanding connective tissue is crucial for dental therapy and hygiene practices.
  • Comprehension of its structures and functions aids in effective treatment planning.
