2019年10月4日 · Goblet cells of the epithelium secrete mucus to trap particles and prevent them from traveling further down respiratory passages. The coordinated action of cilia on longer columnar cells facing the lumen moves the mucus along …

2023年8月3日 · The cells are arranged tightly adjacent to one other, and goblet cells are present in between cells in the layer of ciliated pseudostratified columnar epithelium. These mucus-producing goblet cells extend up to the apical surface.

2024年4月6日 · The goblet cells between columnar cells of the tissue produce mucus which helps to lubricate the linings of the reproductive and respiratory tracts and the majority in the tract for urinary elimination.

2023年11月3日 · Goblet cells are unicellular intraepithelial mucin-secreting glands scattered within simple epithelia, such as cuboidal, columnar, and pseudostratified epithelia. Their name corresponds to their shape, as they resemble a goblet, with their narrow bases and wide apex.

Pseudostratified columnar epithelium is a type of epithelium that, though comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified columnar epithelium. A stratified epithelium rarely occurs as squamous or cuboidal.

This tissue often has numerous mucous-producing goblet cells, shown in turquoise in the illustration overlays for Figures 1 and 2. As seen in both of these examples, the cells of pseudostratified columnar epithelium often contains cilia on their apical side, which help to sweep/move the mucous across the surface of the tissue.

Goblet Cells produce mucus. It contains: Mucin: helps maintain epithelial moisture and traps particulate material and pathogens moving through the airway. *** Ciliated cells and Mucus, together are responsible for very important “Mucociliary clearance function”.

Histology of the pseudostratified columnar epithelium with cilia and goblet cells (respiratory epithelium) that lines the lumen of the trachea.

Goblet Cells - scattered cells that secrete mucus. The secretion granules are clustered within the cells. This is seen as a clear circular area due to the mucus being extracted during preparation of the specimen.

What is the role of the goblet cells in pseudostratified ciliated columnar epithelial tissue of the upper respiratory tract?
