Connective Tissue : 

Connective Tissue Power Point designed to put the components together

Loose Connective Tissue : 

Loose Connective Tissue Areolar Cells: fibroblasts, macrophages, plasma cells, mast cells, adipocytes, a few white blood cells Fibers: collagen, elastic reticular Ground substance: hyaluronic acid, chondroitin sulfate, dermatan sulfate, keratin sulfate Forms the subcutaneous layer (skin to underlying tissues)

Loose Connective Tissue : 

Loose Connective Tissue Loose Connective Tissue: Adipose tissue Cells: adipocytes Found where areolar c.t. is located Matrix fibers: small numbers of collagen and elastic fibers Matrix Ground substance: glycosamino- and proteoglycans in small amounts The contents of adipocytes (triglycerides) get so big they push all the cytoplasm and nuclear material to the very periphery. The adipocytes take up most of the volume of the tissue.

Loose Connective Tissue : 

Loose Connective Tissue Reticular Connective Tissue Cells: reticular cells Fibers: reticular fibers - a subtype of collagen fibers, are well stained with silver salts; that's why they are also known as argyrophilic fibers; they form a meshwork Ground Substance: reticular substance extracellular fluid Forms STROMA of the liver, spleen, lymph nodes and helps bind together smooth muscle cells IN the spleen, filters, lymph filters to remove bacteria Great Picture and description http://www.anatomytime.com/2010/10/recticular-connective-tissue.html http://www.youtube.com/watch?v=GfUFM9-Tm5k

Dense Connective Tissue : 

Dense Connective Tissue Dense Regular Connective Tissue Cells: fibroblasts appear in rows between the fibers Matrix fibers: bundles of collagen fibers regularly arranged in parallel patterns Ground substance: glycosaminoglycans and proteoglycans in very limited amounts Tendons and most ligaments

Dense Connective Tissue : 

Dense Connective Tissue Dense Irregular Connective Tissue Cells: collagen fibers irregularly arranged Fibers (cells): numerous collagen and elastin fibers Ground substance: moderate amounts of glycosaminoglycans and proteoglycans Locations: reticular layer of dermis; periosteum, perichondrium

Dense Connective Tissue : 

Dense Connective Tissue Elastic Connective Tissue Cells: fibroblasts Matrix fibers: coarse parallel elastic fibers bound together by a small amount of delicate CT with fibroblasts, collagen fibers Matrix ground substance: Elastic = - frequent branching and fusion of elastic fibers - found in elastic ligaments (e.g., true vocal cords, surrounding aorta as fenestrated membranes) Found in elastic arteries, lung tissue

Elastic Fiber : 

Elastic Fiber Elastic Fiber  a type of fiber found in the intercellular substance of connective tissue. Elastic fibers are long homogeneous threads no more than two or three micrometers thick. They are intertwined and branched, forming a delicate network that refracts light strongly. The fibers consist of the stable elastic protein elastin, which withstands boiling. Elastic fibers are found in the walls of blood vessels, elastic cartilage, and areolar tissue.

Cartilage : 

Cartilage Hyaline cartilage Cells: chondrocytes Matrix fibers: cartilage Ground substance: a resilient gel Most hyaline cartilage is surrounded by perichondrium (except at articular cartilage sites). Hyaline the most abundant cartilage type in the body.

What is perichondrium? : 

What is perichondrium? The perichondrium is a layer of dense irregular connective tissue which surrounds the cartilage of developing bone. It consists of two separate layers: an outer fibrous layer and inner chondrogenic layer. The fibrous layer contains fibroblasts, which produce collagenous fibers. The chondrogenic layer remains undifferentiated and can form chondroblasts or chondrocytes. Perichondrium can be found around the perimeter of elastic cartilage and hyaline cartilage. Fibrocartilage and articular cartilage both lack perichondrium.

Cartilage : 

Cartilage Fibrocartilage Cells: chondrocytes Matrix fibers: collagen fibers Matrix ground substance: ground substance rich in proteoglycan Located in the pubic symphysis, intervertebral discs

Bone Tissue : 

Bone Tissue Cell: osteoblasts, osteocytes, osteoclasts Extracellular matrix: fibers: collagen fibers Solid ground substance the predominant component is calcium phosphate mostly in the form of hydroxyapatite crystals and some in amorphous state; small amounts of magnesium phosphate and very scarce glycosaminoglycans and proteoglycans are also found

Liquid Connective Tissue : 

Liquid Connective Tissue Blood Cells: formed elements which are red blood cells (red blood cells), white blood cells (leukocytes), and platelets (thrombocytes). Matrix: LIQUID ground substance =plasma (a pale yellow fluid that consists mostly of water with a wide variety of dissolved substances-nutrients, wastes, enzymes, plasma proteins, hormones, respiratory gases and ions).

Liquid Connective Tissue : 

Liquid Connective Tissue Lymph Cells: several types of cells Matrix: a clear liquid that is similar to blood plasma with much less protein
