| Question | Answer |
|---|---|
| mesenchyne | STRUCTURES: sperm-shaped FUNCTIONS: gives rise to all other connective tissue LOCATIONS: embryo |
| bone | STRUCTURES: collagen fibers, well-vascularized, osteocytes, lacunae, central canal, lamella FUNCTIONS: supports, protects, stores: calcium, fat, marrow LOCATIONS: bones |
| blood | STRUCTURES: red and white blood cells in a fluid matrix, no nuclei FUNCTIONS: transports: resp. gases, nutrients, wastes, substances LOCATIONS: blood vessels |
| nerve cell | STRUCTURES: branching cells, nuclei of supporting cells, cell body of neuron, neuron processes FUNCTIONS: transmits electrical signals from sensory receptors to muscles and glands LOCATIONS: brain, spinal cord, nerves |
| dense regular | STRUCTURES: parallel collagen fibers, elastin fibers, cell: fibroblast FUNCTIONS: connects muscles to: bones and muscles LOCATIONS: tendons, ligaments |
| dense irregular | STRUCTURES: irreg. arranged, fibers: collagen and elastic, cell: fibroblast FUNCTIONS: withstand pressure,structural strength LOCATIONS: dermis of the skin |
| areolar | STRUCTURES: fibers: collagen, elastic, reticular, cell: fibroblast, mast cells, white blood cells FUNCTIONS: wraps and cushions tissues LOCATIONS: widely distributed under epithelia of body,capillaries |
| adipose | STRUCTURES: fat cells, nuclei pushed to the side, adipocytes FUNCTIONS: insulates heat, provides reserve fuel, supports and protects organs LOCATIONS: under skins, kidneys and eyeballs, breasts |
| reticular | STRUCTURES: reticular fibers (look like branches), cells: lymphocytes, reticular cells FUNCTIONS: supports other cell types: white blood cells, microphages, mast cells LOCATIONS: |
| hyaline cartilage | STRUCTURES: amorphous, collagen fibers, chondroblasts, chondrocytes in lacunae FUNCTIONS: supports, reinforces LOCATIONS: cartilages of the ribs, nose, trachea |
| elastic cartilage | STRUCTURES: similar to hyaline, more elastic fibers, chondrocytes FUNCTIONS: maintians shape, flexibility LOCATIONS:supports the external ear |
| fibrocartilage | STRUCTURES: like hyaline, collagen fibers FUNCTIONS: absorb shock LOCATIONS: invertebral discs |
| characteristics of CT | - highly vascularized - multicellular - non-cellular, nonliving material (matrix) between cells |
| neuroglia | small supporting cells around the neurons |
