Simple columnar epithelium consists of tall, narrow cells having considerably greater height than width.
單層柱狀上皮由高桂狀上皮細胞組成,細胞的高度顯著大于細胞的寬度。
Epithelial tissue is the pseudostratified ciliated columnar epithelium, more Fabricius nodes are located in the natural layer.
黏膜上皮全部為假複層柱狀上皮,黏膜的固有膜内腔上囊小結也相對發達。
The rectum mucosa epithelium is composed of single-layer columnar epithelium and pseudostratified ciliated columnar epithelium.
直腸單層柱狀上皮與假複層纖毛柱狀上皮共存。
Transmission electron microscope indicated a polarized columnar epithelium in monolayer with basally nuclei and tight junction.
透射電鏡觀察顯示培養的上皮具有極性,表面有微絨毛,細胞間緊密連接及細胞間糖原沉積。
The inner face of sack was covered with a sheet of columnar epithelium where some of goblet cell were found between the columnar epithelium.
該囊腔的内面被覆一層柱狀上皮,其間夾雜有較多的杯狀細胞。
柱狀上皮(columnar epithelium)是上皮組織的一種類型,其細胞呈細長柱狀排列,細胞核通常靠近基底部。這類上皮細胞根據結構和功能可分為多種亞型,廣泛分布于人體多個器官系統中,在分泌、吸收和保護等方面發揮關鍵作用。
柱狀上皮的細胞高度顯著大于寬度,細胞質内含有豐富的細胞器以適應其功能需求。根據細胞頂部特化結構可分為:
柱狀上皮主要承擔以下生理功能:
柱狀上皮的異常增生可能提示病變,例如巴雷特食管中食管複層鱗狀上皮被柱狀上皮替代,增加癌變風險(來源:Nature Reviews Disease Primers綜述文獻。
柱狀上皮(Columnar Epithelium)是一種由高柱狀細胞構成的上皮組織,細胞高度顯著大于寬度,核多呈橢圓形且靠近細胞基底部。以下是詳細解釋:
