Lab 4 Flashcards
Connective tissues
Binds, supports, insulates, transports
Classes of connective tissue
Connective tissue proper
Cartilage
Bone
Blood
Fibers
Provide support network in a connective tissue
Connective tissue proper cell type
Fibroblast
Types of fibers
Collagen
Elastic
Reticular
Collagen fibers
Thick, light-staining strands
Provide tensile strength
Elastic fibers
Thin, dark-staining strands
Provide resiliency
Reticular fibers
Form framework to help stabilize and support many organs
Loose (areolar) connective tissue
Description
Function
Location
Semi-fluid ground substance containing collagen and elastic fibers loosely arranged around fibroblasts and other cells
Wraps and cushions organs
Found beneath epithelium, surrounding organs and capillaries
Dense connective tissue
Characterized by closely packed collagen fibers with little ground substance
Dense regular connective tissue
Description
Function
Location
Closely packed collagen fibers;provides great tensile strength when pulled in direction of fibers; fibroblasts are arranged in rows between fibers
Binding and connecting
Tendons, aponeuroses and ligaments
Dense irregular connective tissue
Description
Function
Location
Irregularly arranges bundles; provides tensile strength in all directions
Binding and connecting
Joint capsules, dermis or skin, submucosa of digestive tract
Adipose tissue
Description
Function
Location
Cells specialized for fat storage, resembles a fishnet, cytoplasm and nucleus pushed to one side but fat filled vacuole
Storage of fat
Hypodermics of skin, surrounding kidneys, eyes and other organs, breast tissue
