DefintionTerm
Cells responsible for main function of organ
Dark bands of muscle
Produces connective tissues
# corresponds to the energy needs of the cell
Component of microfilament
Collagen type in CT proper
Collagen type in basal lamina
Proteins which span the bilayer
Tissue where collagen fibers are arranged without definite orientation
Propels material over epithelium
Transects the I band
Synthesizes collagen, elastin, etc.
Non-differentiated/fused myoblast cells
First step of collagen synthesis
Permits flow of signals between cells
Cells are flat and very thin, single layer
Fat cells where mitochondria produce ATP
Disappears when muscle is contracted
Tissue where collagen bundles are in definite pattern
Facilitates movement of molecules in and out of cell
Connective tissue which surrounds fascicle
Muscle type that contains few mitochondria/myoglobin
Site of intracellular digestion
Connective tissue which surrounds entire muscle
Accumulation of residual bodies with age
Type of tissue that surrounds small blood vessels
Fourth step of collagen synthesis
Assembly of 9+2 microtubules
Organelle which is responsible for producing ATP
Cell division which produces 2 haploid cells
Adheres epithelial cell to basement membrane
DefintionTerm
Light bands of muscle
Increase absorption, 'brush' border
Stain with acidic dyes
Flattened/elongated top nuclei, multiple layers, dark top layer
Entry/progression into each phase of mitosis is controlled by
Stain black with silver stain
Cells vary in height, but tend to be as long as they are tall
Prevents flow of materials between epithelial cells
Cell is metabolically functional but cannot divide
Muscle type that contains abundant mitochondria/myoglobin
Most common dye
Invaginations of sarcolemma
Carry vesicles towards MTOC
Sixth step of collagen synthesis
Cell division which produces 2 diploid cells
Outermost component of the cell
Exocytosis of proteins/glycoproteins
Comprises interface between two cardiac muscle cells
Membrane formed by basal lamina and reticular lamina
Supporting tissue of organs
Tool used for sectioning paraffin-embedded tissues for light microscopy
Binds with elastin to form elastic fibers
Carry organelles towards + end of microtubules
Largest GAG/non-sulfated GAG
Glands which secrete into bloodsteam/cells
One of the best fixatives for routine light microscopy
Cells appear to be in layers, but all cells are in contact with basement membrane
Organelle which stains dark due to rRNA
Gives rough ER it's name
Sequesters calcium ions
Cells which are completely undifferentiated, divide asymmetrically and infrequently
DefintionTerm
Adheres one epithelial cell to another
Muscle fibers which transmit sensory information
Flattened/elongated top nuclei, multiple layers, normal top layer
Responsible for movement of flagella and cilia
Collagen type in most cartilage
Electron dense, coarse granules in the nucleus
Cells are taller than they are wide
Contracts muscle fiber, extends from Z line to Z line
Third step of collagen synthesis
Oxidizes hydrogen peroxide
Organelle prominent in cells specialized in phospholipid synthesis
Unicellular gland
Lightly stained areas in the nucleus
Component of microfilament
Glands which retain connection with epithelial surface
Provides adhesion for epithelial cells
Stain with basic dyes
Connective tissue which surrounds individual fibers
Vesicle buds off and is secreted
Reason why nucleolus is dark staining
Secretion of whole cell
Organelle prominent in cells specialized in protein secretion

Second step of collagen synthesis
Cell capable of dividing but is not currently going through cell cycle
Fat cells where mitochondria produce heat
Bundle of muscle fibers
Fifth step of collagen synthesis
Collagen type in reticular tissue
