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