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 |
