cells Flashcards
what is the largest cell in the body?
ovum/oocyte
what is the smallest cell?
granule cell of the cerebrum
what is the smallest cell by volume?
sperm
what is the shape of the oocyte nucleus?
round
what is the shape of the nuclei of the gray loss cell?
round to oval
what is the shape of the nuclei of the fibroblast?
elongated and fusiform
why is the oocyte nucleus pale?
it is actively synthesizing proteins and the chromatin is unwound
what makes the nucleus visible in an oocyte
euchromatic- heterochromatim clumps (blue dots)
why can’t the nucleolus be clearly seen in fibroblasts and granulosa cells?
heterochromatic- chromatin is tightly wounded
what are goblet cells filled with?
mucin
what are the spaces between fibers in living tissue that is washed away during processing filled with?
extracellular matrix
what is the purpose of elastic fibers?
give blood vessel walls their elasticity so they can yield to changes in blood pressure
what are satellite cells?
smaller cells with round nuclei around the neuronal cell bodies
