Study Notes

Overview of Connective Tissue

Comprises a group of tissues that maintain the body’s form and provide internal support and cohesion.
Varies in density, cellularity, and degree of specialization.

Characteristics of Connective Tissue

Contains cells (e.g., fibroblasts, adipocytes, macrophages, mast cells, plasma cells, eosinophils) in a matrix made of glycoproteins, fibrous proteins, and glycosaminoglycans.
Extracellular matrix serves mechanical functions in structures like ligaments, tendons, and bones.

Types of Connective Tissue Cells

Fixed Cells: Fibroblasts, adipocytes, macrophages, mast cells.
Transient Cells: Plasma cells, eosinophils.

Non-Cellular Substrate

Also called extracellular matrix or ground substance.
Amorphous, gelatinous, transparent material that fills spaces between cells and fibers, facilitating transport of metabolites.
Composed of glycosaminoglycans (GAGs) that form proteoglycans, effective at resisting compressive forces.

Fibers in Connective Tissue

Secreted by fibroblasts to create a supporting network for cell attachment.
Three main types of fibers:
- Elastic Fibers: Provide flexibility.
- Collagen Fibers: Impart strength.
- Reticular Fibers: Form supportive networks.

Classification of Connective Tissue

Connective Tissue Proper
- Loose Connective Tissue: E.g., areolar, adipose, reticular.
- Dense Connective Tissue: E.g., regular, irregular.
Specialized Connective Tissue
- Supporting Connective Tissue: Cartilage (hyaline, fibrocartilage, elastic), Bone (compact and spongy).
- Fluid Connective Tissue: Blood, Lymph.

Connective Tissue Proper

Composed of numerous cells and loose fibers.
Slightly viscous fluid; foundational for other tissues.

Loose Connective Tissue Types

Areolar: Covers muscle fibers, connects/supports tissues.
Adipose: Functions as energy store, thermally insulates.
Reticular: Provides framework in organs, contains cells like monocytes and lymphocytes.

Dense Connective Tissue

Dense Regular: Collagen fibers arranged in parallel, offers tensile strength.
Dense Irregular: Fibers arranged in various directions, provides strength in multiple directions.

Specialized Connective Tissue

Cartilage: Contains chondrocytes within a matrix; three types (hyaline, fibrocartilage, elastic).
Bone: Composed of compact and spongy types, strong structural support.
Blood: A fluid tissue comprising plasma and various blood cells (erythrocytes, leucocytes, platelets), constantly circulating in the body.
