Defintion	Term
Flattened/elongated top nuclei, multiple layers, dark top layer
Component of microfilament
Collagen type in CT proper
Fourth step of collagen synthesis
Outermost component of the cell
Lightly stained areas in the nucleus
Connective tissue which surrounds individual fibers
Provides adhesion for epithelial cells
Produces connective tissues
Second step of collagen synthesis
Stain black with silver stain
Binds with elastin to form elastic fibers
Assembly of 9+2 microtubules
Light bands of muscle
Sixth step of collagen synthesis
Transects the I band
One of the best fixatives for routine light microscopy
Cells are flat and very thin, single layer
Sequesters calcium ions
Increase absorption, 'brush' border
Muscle type that contains few mitochondria/myoglobin
Muscle type that contains abundant mitochondria/myoglobin
Cell capable of dividing but is not currently going through cell cycle
Connective tissue which surrounds fascicle
Facilitates movement of molecules in and out of cell
Stain with acidic dyes
Cells vary in height, but tend to be as long as they are tall
# corresponds to the energy needs of the cell
Invaginations of sarcolemma
Dark bands of muscle
First step of collagen synthesis

Defintion	Term
Third step of collagen synthesis
Organelle which stains dark due to rRNA
Cells are taller than they are wide
Most common dye
Accumulation of residual bodies with age
Cell division which produces 2 haploid cells
Site of intracellular digestion
Fat cells where mitochondria produce heat
Oxidizes hydrogen peroxide
Tissue where collagen fibers are arranged without definite orientation
Cell division which produces 2 diploid cells
Disappears when muscle is contracted
Tool used for sectioning paraffin-embedded tissues for light microscopy
Example of tumor suppressor gene
Organelle prominent in cells specialized in protein secretion
Cell is metabolically functional but cannot divide
Supporting tissue of organs
Bundle of muscle fibers
Synthesizes collagen, elastin, etc.
Propels material over epithelium
Responsible for movement of flagella and cilia
Entry/progression into each phase of mitosis is controlled by
Contracts muscle fiber, extends from Z line to Z line
Permits flow of signals between cells
Collagen type in basal lamina
Flattened/elongated top nuclei, multiple layers, normal top layer
Proteins which span the bilayer
Carry vesicles towards MTOC
Non-differentiated/fused myoblast cells
Adheres one epithelial cell to another
Cells appear to be in layers, but all cells are in contact with basement membrane

Defintion	Term
Unicellular gland
Muscle fibers which transmit sensory information
Prevents flow of materials between epithelial cells
Exocytosis of proteins/glycoproteins
Organelle prominent in cells specialized in phospholipid synthesis
Cells which are completely undifferentiated, divide asymmetrically and infrequently
Membrane formed by basal lamina and reticular lamina
Tissue where collagen bundles are in definite pattern
Adheres epithelial cell to basement membrane
Fifth step of collagen synthesis
Organelle which is responsible for producing ATP

Reason why nucleolus is dark staining
Fat cells where mitochondria produce ATP
Vesicle buds off and is secreted
Connective tissue which surrounds entire muscle
Largest GAG/non-sulfated GAG
Carry organelles towards + end of microtubules
Electron dense, coarse granules in the nucleus
Cells responsible for main function of organ
Secretion of whole cell
Gives rough ER it's name

Stain with basic dyes
Component of microfilament
Glands which retain connection with epithelial surface
Collagen type in most cartilage
Type of tissue that surrounds small blood vessels
