Second step of collagen synthesis
Largest GAG/non-sulfated GAG
Type of tissue that surrounds small blood vessels
Sequesters calcium ions
Fourth step of collagen synthesis
Vesicle buds off and is secreted
Secretion of whole cell
Outermost component of the cell
Stain with basic dyes
Unicellular gland
Adheres epithelial cell to basement membrane
Component of microfilament
Collagen type in basal lamina
Component of microfilament
Dark bands of muscle
Site of intracellular digestion
Glands which retain connection with epithelial surface
Facilitates movement of molecules in and out of cell
Cells appear to be in layers, but all cells are in contact with basement membrane
First step of collagen synthesis
Collagen type in most cartilage
Organelle which is responsible for producing ATP
Cells vary in height, but tend to be as long as they are tall
Glands which secrete into bloodsteam/cells
Invaginations of sarcolemma
Stain with acidic dyes
Fat cells where mitochondria produce ATP
Oxidizes hydrogen peroxide
DefintionTerm
Connective tissue which surrounds individual fibers
Organelle prominent in cells specialized in phospholipid synthesis
Propels material over epithelium
Cell capable of dividing but is not currently going through cell cycle
Organelle which stains dark due to rRNA
Permits flow of signals between cells
Contracts muscle fiber, extends from Z line to Z line
Adheres one epithelial cell to another
Non-differentiated/fused myoblast cells
Tool used for sectioning paraffin-embedded tissues for light microscopy
Flattened/elongated top nuclei, multiple layers, normal top layer
Example of tumor suppressor gene
Tissue where collagen fibers are arranged without definite orientation
Third step of collagen synthesis
Cells responsible for main function of organ
Prevents flow of materials between epithelial cells
Organelle prominent in cells specialized in protein secretion
Lightly stained areas in the nucleus
Entry/progression into each phase of mitosis is controlled by
Membrane formed by basal lamina and reticular lamina
Electron dense, coarse granules in the nucleus
Stain black with silver stain
Cell is metabolically functional but cannot divide

Muscle type that contains few mitochondria/myoglobin
Cell division which produces 2 diploid cells
DefintionTerm
Cells which are completely undifferentiated, divide asymmetrically and infrequently
Proteins which span the bilayer
Gives rough ER it's name
Cells are flat and very thin, single layer
Reason why nucleolus is dark staining
