* Connective thread:
* Most abundant and widely distributed in body
* 4 Classes
* Connective waver Proper: fat, unchewable wind of ligaments
* gristle
* Bone Tissue
* Blood
* Connective Tissue Proper:
* Loose- areolar, fat, reticular
* Dense- regular, irregular, elastic
* Cartilage:
* Hyaline, elastic, fibro cartilage
* Bone Tissue-
* Compact vs.
Spongy
* Blood-
* Differentiation complex
* Major Functions of Connective Tissue: Binding and support, Protection (adipose, bone), Insulation, Transportation (blood)
* Characteristics of Connective Tissue-
* Varying degrees of vascularity (cartilage not as vascular)
* Three main elements:
* Cells- separated by non-living extracellular ground substance *Most of connective tissue: extracellular matrix*
* Ground Substance- liquid where diffusion is possible between blood, capillaries, and cells
* Components-interstitial fluid, union proteins (glue), proteoglycans (which keep H2O out of cells and between cells equal slow-wittedness of H2O)
* Fibers
* 3 Types of Fibers:
* Collagen (white fibers)- strongest, most abundant, high tensile strength. *Tendons and Ligaments*
* Elastic- long, thin, elastic fibers forgo stretch *Heart and Lungs and Bottom of Dermis*
* Reticular- short, fine, branched collagenic fibers *Makes matrix more solid*
* Structural Elements of Connective Tissue:
* Blasts- active and secretory cells
* Cytes- mature cells
* Examples:
* Fibroblasts in connective tissue proper build up fiber
* Chondroblasts and Chrondrocytes in cartilage
* Osteoblasts and Osteocytes in bone
* hematopoietic stem cells in bone marrow
* Fat cells, white...If you want to undertake a full essay, order it on our website: Orderessay
