EOG8WHC0K	GO:0005814	1/87	centriole	cellular_component	"A cellular organelle, found close to the nucleus in many eukaryotic cells, consisting of a small cylinder with microtubular walls, 300-500 nm long and 150-250 nm in diameter. It contains nine short, parallel, peripheral microtubular fibrils, each fibril consisting of one complete microtubule fused to two incomplete microtubules. Cells usually have two centrioles, lying at right angles to each other. At division, each pair of centrioles generates another pair and the twin pairs form the pole of the mitotic spindle."

EOG8WHC0K	GO:0035044	1/87	sperm aster formation	biological_process	"Formation and organization of an aster composed of microtubule arrays originating from the sperm basal body and extending virtually to the egg periphery. The sperm aster ensures the appropriate positioning of the male and female pronuclei." [GOC:bf, ISBN:0879694238]
EOG8WHC0K	GO:0030953	1/87	astral microtubule organization	biological_process	"A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of astral microtubules, any of the spindle microtubules that radiate in all directions from the spindle poles." [GOC:mah]
EOG8WHC0K	GO:0005813	1/87	centrosome	cellular_component	"A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle." [GOC:mah, ISBN:0198547684]
EOG8WHC0K	GO:0000242	1/87	pericentriolar material	cellular_component	"A network of small fibers that surrounds the centrioles in cells; contains the microtubule nucleating activity of the centrosome." [GOC:clt, ISBN:0815316194]
EOG8WHC0K	GO:0051297	1/87	centrosome organization	biological_process	"A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a centrosome, a structure comprised of a pair of centrioles and peri-centriolar material from which a microtubule spindle apparatus is organized."
