Connective Tissue
Review of Connective Tissues
Term | Definition |
---|---|
Properties of Connective Tissue | (1) Avascular - little to no bloodflow (2) Most widespread tissue throughout body (3) Connects tissue throughout body |
Types of Proper Connective Tissue | (1) Areolar (2) Dense Regular (3) Adipose (4) Reticular |
Types of Fluid Connective Tissue | Blood |
Types of Supportive Connective Tissue | (1) Hyaline cartilage (2) Fibrocartilage (3)Elastic Cartilage (4) Bone |
Types of Connective Tissue | (1) Proper (2) Fluid (3) Supportive |
Structure of Areolar Tissue | Fluid matrix with many collagen and elastic fibers dispersed throughout |
Function of Areolar Tissue | Binds skin to underlying tissue; fills space |
Location of Areolar Tissue | Around blood vessels and nerves; under skin |
Structure of Reticular | "Grapes on a grapevine" Fibroblasts located around reticular fibers |
Function of Reticular | Internal support for soft organs |
Location of Reticular | Spleen; Liver, Lymph nodes |
Structure of Adipose | Large clear cells that push nuclei to edges |
Location of Adipose | Butt, thighs, breast, abdomen |
Function of Adipose | Insulation, protection of internal organs; long term energy storage |
Structure of Dense Regular | Wavy collagen fibers moving parallel to each other with fibroblasts interspersed |
Function of Dense Regular | Strong, flexible support |
Location of Dense Regular | Tendons |
Structure of Blood | Red blood cells with white blood cells interspersed and platelets |
Function of Blood | Transport oxygen and nutrients and drop of carbon dioxide and wastes |
Location of Blood | In blood vessels |
Structure of Hyaline Cartilage | "Floating eyeballs" Chondrocytes floating in solid matrix |
Function of Hyaline Cartilage | Withstands compressing and pulling forces |
Location of Hyaline Cartilage | Ends of long bones; fetal skeleton |
Structure of Fibrocartilage | Wavy collage fibers with chondrocytes |
Location of Fibrocartilage | Pubic symphysis; intervertebral discs |
Function of Fibrocartilage | Tough support |
Structure of Elastic Cartilage | "Hairy eyeballs" Elastic fibers with floating chondrocytes |
Function of Elastic Cartilage | Elasticity |
Location of Elastic Cartilage | Ear lobes; larynx |
Structure of Osseous (bone) | Tree rings with osteocytes and canaliculi |
Function of Osseous (bone) | Support; protection of organs; production of blood cells |
Location of Osseous (bone) | Skeletal bone |
