Accumulation of residual bodies with age
Lightly stained areas in the nucleus
Cells are taller than they are wide

Third step of collagen synthesis
Cell capable of dividing but is not currently going through cell cycle
Cells vary in height, but tend to be as long as they are tall
Cell division which produces 2 haploid cells
Muscle type that contains abundant mitochondria/myoglobin
Largest GAG/non-sulfated GAG
Outermost component of the cell
Example of tumor suppressor gene
Disappears when muscle is contracted
Carry organelles towards + end of microtubules
Fourth step of collagen synthesis
Unicellular gland
Secretion of whole cell
Collagen type in basal lamina

Connective tissue which surrounds entire muscle
Cells responsible for main function of organ
Sequesters calcium ions
Connective tissue which surrounds fascicle
Adheres epithelial cell to basement membrane
Organelle which is responsible for producing ATP

Facilitates movement of molecules in and out of cell
Invaginations of sarcolemma
Provides adhesion for epithelial cells
Bundle of muscle fibers
Sixth step of collagen synthesis
Flattened/elongated top nuclei, multiple layers, normal top layer
Oxidizes hydrogen peroxide
Collagen type in most cartilage
Gives rough ER it's name
Type of tissue that surrounds small blood vessels
Propels material over epithelium
Site of intracellular digestion
# corresponds to the energy needs of the cell
Glands which secrete into bloodsteam/cells

Cell is metabolically functional but cannot divide
Component of microfilament
One of the best fixatives for routine light microscopy
Organelle prominent in cells specialized in protein secretion
