BIO 223 ct

QuestionAnswer
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
ct with collagen fibers hyaline, elastic, fibrocartilage, bone
ct with elastic fibers regular, irregular, elastic
ct with reticular fibers reticular
cell types within ct: fibroblasts areolar, regular, irregular
cell types within ct: mast cells areolar
adipocytes adipose
chondrocytes in lacunae hyaline, elastic, fibrocartilage
osteocytes in lacunae bone
extracellular matrix nonliving material found between the cells

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
