Study Notes
Connective Tissue Matrix
- Connective tissues have a matrix, a non-living component
- Ground substance is the liquid part of the matrix
- Ground substance contains water, ions, nutrients, metabolites, adhesion proteins, and proteoglycans
Loose Connective Tissues
- Areolar tissue: Found in the lamina propria, a layer beneath mucous membranes
- Reticular tissue: Contains branched collagen fibers, supporting internal structures like the spleen, liver, lymph nodes, and bone marrow
- Adipose tissue: Stores fat; yellow and brown types are found in locations like the armpits, neck, and kidney regions
Specialized Connective Tissue
- Endothelium: Simple squamous epithelium, lining blood and lymph vessels
Dense Connective Tissues
- Elastic tissue: Contains elastin fibers; commonly found in blood vessels, lungs, and vocal cords.
- Dense regular connective tissue: Collagen fibers run parallel with fibroblasts. Found in tendons and ligaments
- Dense irregular connective tissue: Contains irregularly arranged collagen fibers. Found in parts like the skin, and coverings of kidneys, bones, and testes
