  1. Where are the hydrophillic and hydrophobic regions?
    Yellow tails on inside of membrane are HYDROPHOBIC and purple phospholipid heads on outside are HYDROPHILLIC

  2. Which has the more active nucleus?
    The cell on the left has more Euchromatin, and is therefore more active compared to the cell on the right.

  3. Which areas are heterochromatic, euchromatic and where is the nucleolus?
    • Euchromatin = EU
    • Heterochromatin = HC
    • Nucleolus = NU

  4. What cell is this?
    Osteoclast

  5. What is this?
    Mesenchyme

  6. What are these?
    Osteoblasts

  7. What are these?
    Osteocytes

  8. What type of cytoskeleton structure is this? and what does it do?
    Microtubules - how vesicles move within the cell

  9. What type of cytockeleton structure is this? What is the function?
    • Microfilaments- forms pockets in cell membrane when things move in and out of cell, responsible for membrane activity like endo and exocytosis
    • Ex: actin or myosin

  10. What type of cytoskeleton structures are these? Function?
    Intermediate filaments- provie strength and define the shape of the cell as a whole

  11. What are these as a whole? and what is the arrow pointing to?
    As a whole it is a centriole and the arrow is pointing to one individual microtubule that makes up the centriole. *Usually 9 groups of 3 microtubules each*

  12. What is this?
    Tight Junction

  13. What is this? and what are the filaments in it that make it different than the others?
    Zonula Adherens - has actin filaments

  14. What is this? and what are the filaments on the outside called?
    Macula adherens - plaque filaments

  15. What is this? what makes it different?
    Gap junction- has INTERLOCKING transmembrane proteins

  16. What is the arrow pointing to?
    transmembrane proteins

  17. What is this?
    Desmosome - macula adherens

  18. What is this? and what is the red area?
    • Hemidesmosome
    • Basement membrane

  19. What are these?
    Cilia

  20. what are these?
    microvilli

  21. What is this and what are the individual peices?
    Brush border made of microvilli

  22. what is this? describe where they are usually found?
    stereocilia - non moving, usually sense organs

  23. what is this basic tissue?
    epithelium

  24. what type of basic tissue is this?
    simple squamous epithelium

  25. what type of tissue is this? where is it found?
    • Simple squamous epithelium
    • found in body cavity lining- serous membranes

  26. what are the white arrows pointing to?
    mesothelium

  27. What type of cells are these?
    Simple cuboidal epithelium

  28. what type of tissue is this?
    simple columnar epithelium

  29. what type of tissue is this? where is it commonly found?
    • pseudostratified columnar epithelium
    • found ciliated in the respiratory system

  30. what type of tissue is this? is it keratinized? where is it found?
    • stratified squamous epithelium
    • non-keratinized
    • cornea

  31. what type of tissue is this? is it keratinized?
    • stratified squamous epithelium
    • yes it is keratinized

  32. what type of tissue is this? how many layers does it usually have? where is it usually found?
    • stratified columnnar epithelium
    • 3-5 layers
    • large ducts of glands

  33. what type of tissue is this? how many layers does it usually have? where is it found?
    • sratified cuboidal epithelium
    • normally 2 layers (no more than 3)
    • found in smaller ducts of glands
