A&P chpt 4 conn tis
| Question | Answer |
|---|---|
| connective tissue proper | con tissue that contains varied cell populations and fiber types surrounded by a syrupy ground substance |
| fluid connective tissues | have distinctive populations of cells suspended in a watery matrix that contains dissolved proteins. the two types of fluid conn tissues are blood and lymph |
| supporting connective tissues | have a less diverse cell population than connective tissue proper and a dense matrix with closely packed fibers. the two types are cartilage and bone |
| types of connective tissue proper | fibroblasts, fibrocytes, macrophages, adipocytes, mesenchymal cells, melanocytes, mast cells, lymphocytes, and microphages |
| 3 types of fibers in connective tissue | collagen fibers, reticular fibers, and elastic fibers |
| Embryonic connective tissue | the first connective tissue to appear in an embryo |
| classifications of connective tissue proper | loose connective tissue or dense connective tissue |
| types of loose connective tissue | areolar tissue, adipose tissue (white fat and brown fat), and reticular tissue. |
| Dense connective tissue | most of this volume consists of fibers. two types are dense regular and dense irregular |
| Blood and lymph | connective tissues that contain distinctive contain distinctive collections of cells in a fluid matrix |
| plasma | the watery matrix of blood |
| arteries | carry blood away from the heart and toward capillaries |
| veins | return blood to the heart |
| supporting connective tissues | cartilage and bone, because they support the rest of the body |
| three types of cartilage | hyaline, elastic, fribrous |
| chondrocytes | rely on diffusion through the avascular matrix to obtain nutrients |
| cartilage | grows by two mechanisms: interstitial growth and appositional growth |
| bone | consists of osteocytes, little ground substance, and a dense, mineralized matrix consisting of calcium salts and collagen fibers |
| osteocytes | depend on diffusion through canaliculi for nutrient intake |
| serous membranes | line the body's sealed internal cavities |
| cutaneous membrane | aka skin, covers the body surface |
| synovial membranes | form an incomplete lining within the cavities of synovial joints |
