    Study Notes

    Connective Tissue Histology Overview

    • Connective tissue is diverse, providing structural support, defense, and more
    • It's found throughout the body, supporting various organs and tissues
    • Key functions include support, defense, storage, exchange, and healing

    Types of Connective Tissue

    • Loose Connective Tissue:

      • Contains loosely arranged collagen fibers and ground substance
      • Provides support and flexibility
      • Found beneath epithelial tissues

    • Dense Connective Tissue:

      • Regular: Fibers are densely packed and aligned, providing strength in one direction (tendons, ligaments)
      • Irregular: Fibers are densely packed but irregularly arranged, providing strength in multiple directions (dermis of skin)

    • Adipose Tissue (Fat Tissue):

      • Predominantly consists of adipocytes, cells that store fat
      • Highly vascularized tissue critical in various bodily functions
      • White adipose tissue is the prevalent type (vs. brown)

    • Cartilaginous Tissue:

      • Another specialized connective tissue type, providing support and flexibility

    • Bone Tissue (Ossification):

      • Forms the skeletal system and is comprised of collagen fibers and hard minerals

    Components of Connective Tissue

    • Extracellular Matrix (ECM): A gel-like substance between cells, aiding in diffusion
      • Ground Substance: The gel-like component, containing glycosaminoglycans (GAGs), proteoglycans, and glycoproteins
      • Fibers: Provide tensile strength and elasticity. Collagen fibers are common, while elastic fibers provide stretchiness. Reticular fibers are another subtype.

    Connective Tissue Cells

    • Fibroblasts: Active cells synthesizing the extracellular matrix
    • Fibrocytes: Inactive form of fibroblasts, found when ECM synthesis is low
    • Adipocytes: Store fat
    • Mast Cells: Involved in immune responses and inflammatory reactions, contain granules with heparin and histamine
    • Macrophages: Phagocytic cells engulfing pathogens, debris
    • Plasma Cells: Produce antibodies
    • Pericytes: Regulate blood flow, and repair tissue
    • Leukocytes (White Blood Cells): Various types contribute to the immune and defense systems
    • Mesenchymal Cells: Multipotent stem cells that differentiate into various connective tissue cells (fibroblasts, adipocytes, osteocytes, chondrocytes)
