Anatomy Quiz #2

  1. Cytology
    Study of cells
  2. Plasma Membrane
    • contains receptors for communcation
    • forms intercellular connections
    • acts as a physical barrier to enclose cell contents
    • regulates material movement into and out of the cell
  3. Cytoplasm
    What are the 3 components of cytoplasm?
    • site of metobolic processes of the cell
    • Stores nutrients and dissolved solutes
    • Three components:
    • - cytosol
    • - inclusions
    • - organelles
  4. Nucleus
    • cell's control center
    • controls protein synthesis
    • directs the functional and structural characteristics of the cell
    • controls all genetic information
  5. Cytosol
    • provides support for organelles
    • serves as viscous medium through which diffusion occurs
  6. Organelles
    carry out specific metabolic activities of the cell
  7. inclusions
    store materials
  8. Nuclear Envelope
    pores in envelope regulate exchange of materials with the cytoplasm
  9. Nuclear Pores
    • openings through the nuclear envelope
    • allow for passage of materials between nucleus and cytoplasm
  10. Nucleolus
    synthesizes rRNA and assembles ribosomes in the nucleus
  11. Smooth Endoplasmic Reticulum (smooth ER)
    • interconnected network of membrane tubules and vesicles; no ribosomes
    • Synthesizes lipids
    • metabolizes carbohydrates
    • detoxifies drugs
    • alcohol
  12. Rough Endoplasmic Reticulum (Rough ER)
    • synthesizes proteins for secretion
    • new proteins for the the plasma membrane and lysosomal enzymes
    • transports and stores molecules
  13. Golgi Apparatus
    • modifies, packages, and sorts newly synthesized proteins for secretion
    • inclusion in new plasma membrane, or lysosomal enzyme synthesis
  14. Lysosomes
    • digest materials or microbes ingested by the cell
    • removes old/damaged organelles
  15. Peroxisomes
    Convert Hydrogren peroxide formed during metabolism to water
  16. Mitochondria
    Synethsize most ATP during cellular respiration; "powerhouses of cell"
  17. Ribosomes
    • Synthesizes protein for:
    • 1. use in the cell
    • 2. secretion, incorporation into plasma membrane or lysosomes
  18. Cytoskeleten
    • Provides structural support
    • facilitates cytoplasmic streaming
    • organelle and cellular motality
  19. Microtubules
    • support cell
    • hold organelles in place
    • direct organelle movement within cell and cell motility as cilia and flagella
    • move chromosomes at cell division
  20. Centrosome
    Organizes microtubules during cell division for movement of chromosomes
  21. Cilia
    Move fluid, mucus, and materials over the cell surface
  22. Flagellum
    Propels sperm cells in human male
  23. Microvilli
    Increase membrane surface area for increased absorption and/or secretion
