Connective Tissues

Contains elastic fibers and its found in the lungs. This tissue allows the lungs to inflate during inhalation and return to their original shape after exhaling

Elastic connective tissue

Packed w/ parallel bundles of collagen fibers and found in tendons. This tissue resists pulling forces applied by muscles

Dense regular

Has a firm, gelatinous ground substance containing collagen fibers. This tissue is found in the tracheal wall to support and prevent it from collapsing

Hyaline cartilage

Found under covering and lining epithelium. Its extracellular matrix contains a loose arrangement of fibers, and its viscous ground substance facilitates the flow of interstitial fluid containing nutrients to epithelial tissues. It also cushions and supports epithelia.

Areolar connective tissue

Contains many elastic fibers in a firm gelatinous ground substance. Located in external ear, auditory tube, and epiglottis

Elastic cartilage

Hard, extracellular matrix forms trabeculae

Spongy bone

Forms a framework in the spleen, bone marrow, and lymph nodes. It contains fine, branching fibers

Reticular connective tissue

It is packed w/ bundles of collagen fibers running in different directions. It is found in the she skin and allows skin to resist pulling forces from many different directions

Dense irregular connective tissue

Fluid extracellular matrix used to transport substances throughout the body

Blood connective tissue

Contains a large number of lipid-storing cells. It is found throughout the body, cushions and insulates organs, and stores lipids for future energy needs

Adipose connective tissue

Hard extracellular matrix containing osteons, involved in protection and support

Compact bone

Firm gelatinous substance packed w/ bundles of collagen fibers. This tissue is found in interveretbral discs, pubic symphasis, and knee meniscus

Fibrocartilage

Fibroblasts produce extracellular matrix for these connective tissue types

Areolar, reticular, adipose, dense regular, dense irregular, elastic

Oestoblasts produce extracellular matrix

Compact, spongy bone

Chondroblasts produce extracellular matrix

Hyaline cartilage, elastic cartilage, fibrocartilage

Fibers not present unless injury occurs. Extracellular matrix not produced by cells present in this tissue
