人的口腔上皮细胞临时装片的制作过程是:擦拭载玻片和盖玻片→在载玻片上滴一滴生理盐水→漱口→用消毒牙签在口腔侧壁上刮取口腔上皮细胞→将牙签在生理盐水中涂抹均匀→盖盖玻片→染色. (1)擦:用洁净的纱布将载玻片、盖玻片擦拭干净. (2)滴:用滴管在洁净的载玻片中央滴一滴生理盐水,保持细胞的正常形态. (3)刮:用凉开水把口漱净,用牙签从口腔腮壁处轻轻刮几下, (4)涂:把牙签上附着的一些碎屑放在载玻片的生理盐水滴中涂几下. (5)盖:盖上盖玻片,先让盖玻片的一边接触生理盐水滴,然后慢慢放下,注意不要留下气泡. (6)染:经碘液染色后.染色的正确方法是把一滴稀碘液滴在盖玻片的一侧, (7)吸:用吸水纸从另一侧吸引,使稀碘液浸润标本的全部; 把制好的口腔上皮细胞装片放在低倍显微镜下观察. 故答案为:(2)生理盐水(4)生理盐水(5)接触;气泡(6)一侧(7)另一侧 |
