Cell division which produces 2 diploid cells
Carry vesicles towards MTOC
Facilitates movement of molecules in and out of cell
Proteins which span the bilayer
Cells are taller than they are wide
Cells which are completely undifferentiated, divide asymmetrically and infrequently
Fat cells where mitochondria produce heat
Stain black with silver stain
Second step of collagen synthesis
Collagen type in basal lamina
Component of microfilament
Comprises interface between two cardiac muscle cells
Cell capable of dividing but is not currently going through cell cycle
Invaginations of sarcolemma
Collagen type in CT proper
Example of tumor suppressor gene
One of the best fixatives for routine light microscopy
Dark bands of muscle
Cells vary in height, but tend to be as long as they are tall
First step of collagen synthesis
Bundle of muscle fibers
Organelle which is responsible for producing ATP
Propels material over epithelium
Tissue where collagen bundles are in definite pattern
Fourth step of collagen synthesis
Provides adhesion for epithelial cells
Organelle which stains dark due to rRNA
Largest GAG/non-sulfated GAG
Non-differentiated/fused myoblast cells
Sequesters calcium ions
Prevents flow of materials between epithelial cells
Adheres epithelial cell to basement membrane
Cells are flat and very thin, single layer
Lightly stained areas in the nucleus
Most common dye
Reason why nucleolus is dark staining
Oxidizes hydrogen peroxide
Cells responsible for main function of organ
Glands which secrete into bloodsteam/cells
Transects the I band
Unicellular gland
Muscle fibers which transmit sensory information
Cell division which produces 2 haploid cells
Organelle prominent in cells specialized in phospholipid synthesis
Fifth step of collagen synthesis
Gives rough ER it's name
Outermost component of the cell
Contracts muscle fiber, extends from Z line to Z line
Membrane formed by basal lamina and reticular lamina
Electron dense, coarse granules in the nucleus
Accumulation of residual bodies with age
Vesicle buds off and is secreted
Cells appear to be in layers, but all cells are in contact with basement membrane
# corresponds to the energy needs of the cell
Binds with elastin to form elastic fibers
Muscle type that contains few mitochondria/myoglobin
Third step of collagen synthesis
Light bands of muscle
Flattened/elongated top nuclei, multiple layers, dark top layer
Connective tissue which surrounds fascicle
Increase absorption, 'brush' border
Connective tissue which surrounds individual fibers
Sixth step of collagen synthesis
Cell is metabolically functional but cannot divide
Responsible for movement of flagella and cilia
Entry/progression into each phase of mitosis is controlled by
Exocytosis of proteins/glycoproteins
Disappears when muscle is contracted
Adheres one epithelial cell to another
