实验一 上皮组织
报告主题:假复层纤毛柱状上皮 主题属性:指定 标本号:27#
材料:豚鼠气管横切片 染色:HE染色
教学要求:掌握假复层纤毛柱状上皮的侧面形态结构。
纤毛 Cilium 杯状细胞 Goblet cell 柱状细胞 Golumnar cell
结缔组织
Connective tissue

Figure1 Pseudostratified epithelium (Guinea pig tracheal section,HE stained,40×10)
假复层纤毛柱状上皮由一层棱柱状细胞构成,垂直切面观,细胞呈柱状,核椭圆,靠近细胞基底部。上皮细胞的游离面有排列整齐的浅红色丝状物,即纤毛。在柱状细胞之间常夹有杯状细胞。基膜染淡红色,清晰可见。
Pseudostratified ciliated columnar epithelium is composed by a layer of prismatic cells of
vertical section view, the cells are columnar; nuclear is ellipse, closed to the cell base department. The epithelial cells of the free surface have aligned pale red filament.There are goblet cells between columnar cells. Basement membrane is dyed into damask, visible clearly.

实验二 骨
报告主题:骨单位 主题属性:指定 标本号:6# 材料:脱钙骨切片 染色:Schmorl氏法块染
教学要求:掌握光镜下骨组织的结构特点。
骨陷窝 Bone lacuna 骨内膜 Endosteum
中央管
Central canal 骨板
Bone lamella
图2 骨单位(脱钙骨切片,Schmorl氏法块染,40×10)
Figure 2 Osteon (Decalcified bone section,Schmorl stained,40×10)
标本中有许多骨单位,其中央为圆形的中央管,多层骨板围绕中央管呈同心圆排列。在骨单位之间有一些不规则排列的间骨板。
There are many specimens bone unit, its centre is a round central tube, multilayerosteone around the central tube is concentric arrangement. There are irrigullararrengmentinterstitial lamella in the osteon.

实验三 肌组织
报告主题:心肌 主题属性:指定 标本号:12# 材料:人心肌切片 染色:HE染色
教学要求:掌握心肌纤维纵断面和横断面的结构特点。
心肌纤维 Cardiac muscle
闰盘 Intercalated disk
图3 心肌纤维 (人心肌切片,HE染色,40×10)
Figure 3 Cardiac muscle (The section of cardiac muscle, HE stained, 40×10)
心肌纤维走向无一定规则,互相平行排列,但有分叉,彼此吻合成网,有横纹但不明显,细胞核单个,卵圆形,位于中央。心肌纤维端端连接处常可见深染的带状结构,是为闰盘,是心肌纤维的特有结构。
The arrengment of myocardial fibers is irregular.Myocardial fibers are parallel arrangement, but have bifurcates,connected with each other into network.There are not obvious horizontal stripes. a single nucleus, ovoid, located in the central. There is a visible hyperchromatic banded structure at the connection of end to end , which is intercalated disc,a special structure of the myocardial fibers.
