Connective tissue Flashcards
adipose CT
Structure :Adipocytes
Function Protects; stores fat; insulates
Location Subcutaneous layer; surrounding kidney and selected other organs
Relatively fewer cells and fi bers than in dense connective tissue; fibers are loosely arranged
Areolar CT
Structure : Fibroblasts; lesser amounts of collagen and elastic fibers; viscous ground substance Function:Binds and packs around organs Location:Surrounding nerves, vessels; subcutaneous layer Relatively fewer cells and fi bers than in dense connective tissue; fi bers are loosely arranged
dense regular CT
Structure :Densely packed collagen fibers are parallel to direction of stress Function: Provides great strength and flexibility primarily in a single direction Location: Tendons and ligaments
dense irregular CT
Structure : Densely packed collagen fi bers are interwoven; fibers are irregularly clumped together and project in all directions Function: Provides tensile strength in all directions Location: Dermis; capsules of organs
reticular CT
Structure :Mesh work of reticular fibers Function: Forms stroma of lymphatic organs Location: Stroma of spleen, liver, lymph nodes, bone marrow Relatively fewer cells and fi bers than in dense connective tissue; fi bers are loosely arranged
elastic CT
Structure : Elastic and collagen fibers are arranged irregularly Function:Provides framework and supports organs Location:Walls of large arteries
describe the general cherecteristics of connective tissue
Binding, support and packaging
Protection, defense and repair
Insulation
