Simple columnar epithelium consists of tall, narrow cells having considerably greater height than width.
单层柱状上皮由高桂状上皮细胞组成,细胞的高度显著大于细胞的宽度。
Epithelial tissue is the pseudostratified ciliated columnar epithelium, more Fabricius nodes are located in the natural layer.
黏膜上皮全部为假复层柱状上皮,黏膜的固有膜内腔上囊小结也相对发达。
The rectum mucosa epithelium is composed of single-layer columnar epithelium and pseudostratified ciliated columnar epithelium.
直肠单层柱状上皮与假复层纤毛柱状上皮共存。
Transmission electron microscope indicated a polarized columnar epithelium in monolayer with basally nuclei and tight junction.
透射电镜观察显示培养的上皮具有极性,表面有微绒毛,细胞间紧密连接及细胞间糖原沉积。
The inner face of sack was covered with a sheet of columnar epithelium where some of goblet cell were found between the columnar epithelium.
该囊腔的内面被覆一层柱状上皮,其间夹杂有较多的杯状细胞。
柱状上皮(columnar epithelium)是上皮组织的一种类型,其细胞呈细长柱状排列,细胞核通常靠近基底部。这类上皮细胞根据结构和功能可分为多种亚型,广泛分布于人体多个器官系统中,在分泌、吸收和保护等方面发挥关键作用。
柱状上皮的细胞高度显著大于宽度,细胞质内含有丰富的细胞器以适应其功能需求。根据细胞顶部特化结构可分为:
柱状上皮主要承担以下生理功能:
柱状上皮的异常增生可能提示病变,例如巴雷特食管中食管复层鳞状上皮被柱状上皮替代,增加癌变风险(来源:Nature Reviews Disease Primers综述文献。
柱状上皮(Columnar Epithelium)是一种由高柱状细胞构成的上皮组织,细胞高度显著大于宽度,核多呈椭圆形且靠近细胞基底部。以下是详细解释:
