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.

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.
