- A goblet cell is a glandular, modified simple columnar epithelial cell whose function is to secrete gel-forming mucins, the major components of mucus.

- Microscopic Anatomy. The nasal and paranasal sinuses are lined with pseudostratified ciliated columnar epithelium. Four types of cells are noted in the sinonasal cavity: ciliated columnar epithelial cells, nonciliated columnar cells, goblet cells, and basal cells.

15 Real Movie Locations You Can Actually Visit While many major films shoot on a closed sound stage, sometimes productions venture out into the real world to create movie magic. Here are 15 locations from famous films that you can actually visit. The Ghostbusters' New York City headquarters sits at 14 North Moore Street on the corner of Varick Street in TriBeCa.

- Goblet cells are scattered among the absorptive cells in the epithelium of the small intestine and colon. These epithelial cells are specialized for secretion of mucus, which facilitates passage of material through the bowel.The name goblet refers to the cell's shape, narrow at the base and bulging apically.hief cells of the stomach secrete the digestive enzymes (pepsins) of the stomach and have the typical appearance of serous-secretory epithelial cells. Secretory vesicles (containing pepsinogen) are clearly visible in the apical cytoplasm of chief cells.

- [Trachea, monkey; x-section, PTS]. The lumen of the trachea is lined by pseudostratified columnar epithelium. Note that all the surface cells have cilia at their free (apical) surface. (What function do these cilia serve in the trachea?) Mucus-secreting unicellular gland cells (goblet cells) are interspersed among the ciliated cells. The term pseudostratified is commonly applied to certain epithelia which, when sectioned, appear to be stratified.

- B. K cells (Figure 14). Killer (K) cells are not a morphologically distinct type of cell. Rather a K cell is any cell that mediates antibody-dependent cellular cytotoxicity (ADCC). In ADCC antibody acts as a link to bring the K cell and the target cell together to allow killing to occur.

Goblet Cells Goblet cells are found scattered among other cells in the epithelium of many organs, especially in the intestinal and respiratory tracts. In some areas, their numbers are rather small relative to other cell types, while in tissues such as the colon, they are much more abundant.

- A gonad or sex gland or reproductive gland is an endocrine gland that produces the gametes (germ cells) of an organism. In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes, are haploid germ cells.

Mucous layer (mucin) issues in dry eyes: role of goblet cells Mucus is the most slippery substance in the human body. Think of these goblet cells as the ball bearings of the eye surface — instead of containing stainless steel they contain mucus. And this is why normal eyes don't squeak when they blink and one of the reasons why dry eyes are so uncomfortable.

- Epithelium: Low columnar to cuboidal cells. Tubules are tightly packed, have straight test tube shape (minimal branching), parallel to each other, straight luminal surface, rest on thin basement membrane, extend to muscularis mucosa; have absorptive cells and goblet cells.

- Goblet Cells. The talent of goblet cells is to secrete mucus, a viscous fluid composed primarily of highly glycosylated proteins called mucins suspended in a solution of electrolytes.ecretion of Mucus. Secretion of mucus from goblet cells is elicited primarily by irritating stimuli rather than in response to hormones. The lumen of the intestinal tract inevitably contains numerous irritants, and in the lung, such things as dust and smoke are potent inducers of goblet cell secretion.

Golgi Apparatus Golgi Apparatus Definition. The Golgi complex is referred to as the manufacturing and the shipping center of the eukaryoric cell. The Golgi apparatus or the Golgi body or Golgi complex or Golgi is a cellular organelle present in most of the cells of the eukaryotic organisms. The Golgi bodies were identified by an Italian biologist Camillo Golgi in the year 1897 and was maned after him in the year 1898.

Functional biology of intestinal goblet cells Goblet cells reside throughout the length of the small and large intestine and are responsible for the production and maintenance of the protective mucus blanket by synthesizing and secreting high-molecular-weight glycoproteins known as mucins.ecause of the unique nature of this highly polarized exocrine cell, the maturational reorganization of the cytoarchitecture and the cellular mechanisms by which goblet cells secrete their products are discussed.

- Goblet cell carcinoid (GCC) is a rare tumor normally occurring in the appendix which displays features of both a neuroendocrine tumor and a more aggressive form of cancer known as an adenocarcinoma. It is usually diagnosed in people over the age of 50. People with this tumor may develop acute appendicitis, abdominal pain, and diarrhea.
