    •           a. flat-squamos
    •           b. cube shaped-cuboidal
    •           c. column like-columnar
    •           d. transitional -can change shape
    •      2. layers of cells (3 basic systems)
    •           a. single layer-simple
    •           b. multi-layered-stratified
    •           c. looks multi-layered but its not- peudostratified
  9. Name the two characteristics of connective tissue
    A. Most abundant tissue in the body

    • B. Consists of two elements

    •                 a. few of them
    •                 b. several kinds
    •     2. Matrix 
    •                a. makes up mos of tissue
  10. What is the definition of Fontanel?
    Space between skull bones at birth, filled with connective tissue
  11. What is a foramen?
    An opening though which blood vessels, nerves or ligaments pass through
  12. What is a fossa?
    A fossa is a trench, shallow depressions in or on a bone
  13. What is a meatus?
    A meatus is a passageway- a channel though bone
  14. What are the two processes that form joints? (articulation)
    1. Condyle-large knucle-like process at the end of the bone

    2. Head-rounded end of a bone
  15. What are the two procesess to which tendons, ligaments and other connective tissue attach?
    1. Spinous Process-spince

    2. Tuberosity-large rounded, roughened process
  16. what are the 3 different types of connective tissue?
    1. Ligaments-connective tissue that holds two bones together

    2. Tendon-connective tissue that attaches muscle to bone

    3. Cartilage-rubbery-like substance that cover the ends of bones forming a joint, it provides cushioing and reduces friction that would destroy the bone.
  17. What are the two division of human skeletal system?
    1. Axial skeleton-has 80 bones

    2. Appendicular skeleton- has 126 bones
