1. Connective tissue consists of cells surrounded by ____________. Protein fibers and ground substance Provides scaffolding for the cells to form tissue, modifies the tissue to support different organs and conditions, relays biochemical signals that control cellular activities, medium for transfer of substances between blood and cells Extracellular matrix

2. Which type of cell can ‘wander’, (migrate) through connective tissue? Helps fight off infection by ‘eating’ bacteria and other foreign bodies Macrophage

3. Which type of cell produces fibers in C.T.? Fibroblast

4. Which type of cell in C.T. releases heparin and histamine in inflammation or an allergic reaction? Mast cell (What does the chemical heparin do? It is an anticoagulant (prevents blood clotting) What does the chemical histamine do? Causes the redness and swelling associated with inflammation and allergic reactions)

5. Which type of C.T. forms delicate, thin membranes? Binds skin to underlying tissue, underlies most layers of epithelium where it helps nourish the epithelium with its blood vessels, and fills spaces between muscles. Areolar C.T.

6. Which type of C.T. stores fat? Layer below the skin, around the kidneys and heart, and behind the eyeballs Store fat for energy insulation, cushioning Adipose tissue

7. Which type of C.T. is composed of thin collagenous fibers arranged in a 3-dimensional network? Liver, spleen, lymph nodes Provides a supportive framework for the solid organs Reticular C.T.

8. Which type of C.T. makes up the tendons and ligaments? Made of many tightly packed collagenous fibers with a fine network of elastic fibers Very strong - able to withstand pulling forces; poor blood supply Dense Regular C.T.

9. Which type of C.T. is found in the dermis? Made of thicker collagen fibers that are interwoven and randomly organized Allows the dermis to withstand tension from many different directions Dense irregular C.T.

10. Which type of C.T. has abundant elastic fibers in parallel strands or branching networks, along with some collagenous fibers. Walls of large arteries, such as the aorta, the heart, and in the airways? Elastic C.T.

11. Which type of cartilage is the most abundant type in the body, and forms the embryonic skeleton. Ends of bones that form joints, soft part of the nose, supportive rings in the airways? Hyaline cartilage

12. Which type of cartilage is the most flexible type of cartilage, found in the external ear and larynx? Elastic cartilage

13. Which type of cartilage is the toughest and is a good shock absorber in the body, and is found in the Intervertebral disks, pelvic girdle, and pads (menisci) of the knee? Fibrocartilage

14. Which type of connective tissue is the most rigid in the body, provides framework for body movement, helps protect internal organs, stores minerals, and makes blood cells? Bone

15. What is the fluid connective tissue in the body? Blood

16. Erythrocyte (Red blood cell) – transports gases

17. Leukocyte (white blood cell) – fights infection

18. Platelet – cell fragment that helps form blood clots

19. Skeletal muscle – striated, voluntary, attaches to bones for body movement

20. Cardiac muscle – striated + intercalated disks, involuntary, heart

21. Smooth muscle – non-striated, involuntary, walls of organs and blood vessels

22. Which type of cell in nervous tissue is a highly specialized cell that can sense changes and respond by transmitting an electrical impulse? To coordinate, regulate and integrate body activities. Neuron

23. There are four types of membranes in the body--serous membranes, mucous membranes, cutaneous membranes, and synovial membranes. Which type of membrane lines body cavities that do open to the outside of the body, and may contain goblet cells? Mucous membranes
