Show Answers:

  1. What are the three types of Connective Tissue?
    • A. Connective Tissue Propper
    • B. Fluid Connective Tissue
    • C. Supporting Connective Tissue
  2. What different cell types make Connective Tissue Proper?
    • fibroblast
    • macrophages
    • adipocytes
  3. In Connective Tissue Proper what three types of fibers contribute to ECMatrix?
    1)Collagen Fibers - Strong flexible,and unbranched.

    2)Elastic Fibers - stretchable and branched.

    3)Reticular Fibers - thin interwoven and branched
  4. Describe the ECF of the Connective Tissue Proper
    called ground substance thick like syrup,filling the spaces between the cells and fibers. (prevents bacteria from moving freely)
  5. Name and describe the two types of Connective Tissue Proper
    • A)Loose Connective Tissue(aka areolar tissue)
    • Functions in supporting epithelial&blood vessels, and in protecting organs.
    • includes fatty tissue.

    • B)Dense Connective Tissue
    • strong tissue that functions in supporting bones, muscles, and organs.
    • include ligaments and tendons
  6. What is Fluid Connective Tissue?
    whole blood and ECMaterial (lymph & plasma)
  7. What are chondrocytes?
    ECMatrix called cartilage
  8. What are the three types of cartilage?
    • Hyaline cartilage(collagen fibers. ex. ribs& sternum)
    • Elastic cartilage(elastic fibers. ex. epiglottis)
    • Fibrocartilage(collagen fibers. ex. spinal column and knee)
  9. what are the two tpes of bone?
    • spongy bone
    • compact bone
  10. What cells produce bone?
    • osteocytes
    • osteoblasts
  11. What is the function of muscle tissue?
    to contract, producing movement; voluntary and involuntary
  12. What are the three types of muscle tissue?
    • skeletal muscle tissue
    • cardiac muscle tissue
    • smooth muscle tissue
  13. Whats the function of the skeletal tissue? (attached tendons)
    usually voluntary movement; (partial repair if damaged)
  14. What is the function of the Cardiac muscle tissue?
    pumping blood through blood vessels, involuntary movement.(little to no repair if damaged)
  15. Where are smooth muscle tissue found?
    What function does it provide?
    • in the walls of blood vessels, and organs.
    • functions in bloodflow and digestion, involuntary. (capable of regerating if damaged)
  16. What is nervous tissue?
    Specialized for conducting electrical impulses (electrochemical) that allows communicating with other cells. Regulates the functions of most organs.
  17. Define neurons:
    nerve cells that transmit electrical signals throughout the body.
  18. Whats the job of the neuroglia?
    • support
    • supplying nutrients, insulating neurons to assist in the propagation of an electical signal.
  19. What are the four membranes?
    • muccous membrane
    • serouse membrane
    • cutaneous membrane
    • synovial membrane
  20. what are the characteristics of the muccous membrane?
    • lines organ systems that are exposed to external environment(digestive, respiratory)
    • protects underlying tissues.
    • secretes muccous that protects epithelial tissue.
  21. What are the characteristics of the serous membrane?
    • lines the subcavities of the ventral body cavitiy.
    • reduces friction between organs by producing serous fluid.
  22. list the characteristics of the cutaneous membrane.
    • our skin
    • thick, waterproof and dry
  23. Where is the synovial membrane located? What is it function?
    • at the joints
    • secrets synovial fluid to reduce friction
