Study Notes
Loose Connective Tissue
- Subdivided into three main types: Areolar, Adipose, and Reticular
- Provides support and holds organs in place
Areolar Tissue
- Covers muscle fibers, ensuring structural integrity
- Located beneath the epidermis for cushioning and support
- Found surrounding mucous membranes, playing a protective role
- Envelops nerves and blood vessels, facilitating communication and circulation
Adipose Tissue
- Composed of a matrix of areolar tissue, crucial for energy storage
- White Adipose Tissue:
- Accounts for 20-25% of body weight
- Functions include supporting structures, providing thermal insulation, and serving as an energy reserve
- Brown Adipose Tissue:
- Generates heat, particularly important for newborns to maintain body temperature
Reticular Tissue
- Characterized by fine branching reticular fibers in a semi-solid matrix
- Contains reticular cells, monocytes, and lymphocytes, contributing to immune function
- Primarily found in lymph nodes and other lymphatic organs, playing a role in filtration and immune response
Dense Connective Tissue
- Two types: Dense Irregular and Dense Regular
- Dense Irregular:
- Composed of collagen fibers and fibroblasts, providing strength in multiple directions
- Contains capillaries and elastin for flexibility and nourishment
- Dense Regular:
- Made up of tightly packed collagen fibers aligning in one direction, providing tensile strength
- Contains fewer capillaries and fibroblasts compared to dense irregular tissue, leading to slower healing processes
