Cell division which produces 2 haploid cells
Electron dense, coarse granules in the nucleus
Bundle of muscle fibers
Fat cells where mitochondria produce heat

Muscle type that contains few mitochondria/myoglobin
DefintionTerm
Unicellular gland

Light bands of muscle
# corresponds to the energy needs of the cell
Flattened/elongated top nuclei, multiple layers, normal top layer
Non-differentiated/fused myoblast cells
Glands which retain connection with epithelial surface

Component of microfilament
Vesicle buds off and is secreted
Membrane formed by basal lamina and reticular lamina
Cell division which produces 2 diploid cells
Stain with acidic dyes
