Histology

6. mechanism by which cells signal to themselves
8. comprises the microfilaments
9. plasmalemma invaginates and forms a small vesicle that buds off into the cytoplasm
10. scattered magenta particles, using Periodic acid-Schiff Reagent, in the cytoplasm of liver cells.
11. spherical to oblong membrane-delimited organelles.
12. Hemidesmosomes connect cells to the basement membrane complex by way of specific cell-surface matrix receptor proteins called what?
14. have heterochromatic nuclei and only a thin rim of cytoplasm
17. largest organelle within the cell
18. synthesized by smooth endoplasmic reticulum
21. attachment point for microtubules emanating from opposite centrosomes

23. makes up about half of the cell volume and contains water, ions, sugars, amino acids, nucleotides, and myriad other molecules.
24. each of this organelle is formed from two spherical subunits of different sizes
25. Prevents unordered mixing of different biochemical pathways and allows the cells to increase in size by ordered delivery of membrane-delimited molecules to their appropriate destinations.

13. roughly circular basophilic region within the nucleus
15. divides into two during prophase
16. Describes tissue components that stain with acid dyes
19. cell uptake of fluid
20. disklike, cell-to-cell contacts that are particularly well developed in the epidermis of the skin.
