Example of tumor suppressor gene
Stain with basic dyes
Most common dye
Comprises interface between two cardiac muscle cells
Synthesizes collagen, elastin, etc.
Outermost component of the cell
Cells vary in height, but tend to be as long as they are tall
Flattened/elongated top nuclei, multiple layers, normal top layer
Collagen type in basal lamina
Provides adhesion for epithelial cells
Contracts muscle fiber, extends from Z line to Z line
Muscle type that contains abundant mitochondria/myoglobin
Muscle fibers which transmit sensory information
Cell division which produces 2 haploid cells
Produces connective tissues
Fat cells where mitochondria produce heat
Cells responsible for main function of organ

Type of tissue that surrounds small blood vessels
Second step of collagen synthesis
Glands which secrete into bloodsteam/cells
Vesicle buds off and is secreted
