connective tissue
Randomly oriented collagenous fibers of varying size in a thin spread of loose areolar connective tissue (magnified about 370 Γ).
Loose areolar connective tissue is a widely distributed, relatively unspecialized tissue that serves as a prototype for connective tissues in the body.1
While it is found throughout the body, specific examples of its presence and specialized forms include:
- Synovial Membranes: This tissue forms the synovial membrane, which lines joint capsules and secretes viscous synovial fluid to lubricate and nourish joint surfaces.12
- Tendon Sheaths: Similar loose vascular tissue forms protective sheaths around tendons, particularly where they pass over bony prominences, such as the flexor tendons in the hands and feet.12
- Adipose Tissue: This is a specialized variant of loose areolar tissue where large numbers of adipose cells predominate.1
- Extensive Networks: Loose connective tissue often contains extensive networks of elastic fibers that branch and reunite throughout the tissue.3
