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