Absolutely. This type of epithelial cell is found mainly in the trachea and respiratory tract, and any system open to the outside must have mucous to keep it functioning properly for diffusion and cell health. Goblet cells make the mucous, and they are found in respiratory, digestive and reproductive system epithelium.YESYes. You have them in bronchial epithelium, probably.
psuedostratified ciliated columnar epithelial cells and goblet cells
I would say chief cells since they secrete pesinogen whereas parietal cells secrete HCl which tecnically aids in chemical digestion but has other functions as welll. Obviously, HCl alone is not enough to perform chemical digestion which is why more complex molecules such as pesinogen which is converted to pepsin is produced.
The cells found at the outer layer of your skin (e.g. on your arm) are dead. It's easier to get a good look at the cell of the mucous membranes.
The cell membrane is a phospholipid bilayer that is described as a "Fluid Mosaic." The mosaic consists of various glycoproteins and also cholesterol. The phospholipid bilayer contains phosopholips, which are composed of a unit of glycerol, two hydrophobic fatty acids and a hydrophilic PO4 head. Glycolipids and glycoproteins, collectively the Glycocalyx, are on the surface and involved in cell signalling. Cholesterol helps regulate fluidity. Intrinsic proteins (such as aquaporins) facilitate diffusion and extrinsic proteins are involved in active transport.
Mucous cells are cells which secrete mucous. They are usually found in mucous membranes. Mucous is a slippery product made from glycoproteins and water.

Parietal cells (or oxyntic cells) are epithelium cells found in the gastric mucosa, they secrete hydrochloric acid (HCl) and intrinsic factor (which is required for vitamin B12 absorption). Chief cells are not the same as parietal cells. Chief cells secrete pepsinogen and rennin.
epithelium or epithelial cells
mucus protects the epithelium for the acidity in the stomach.
You may be thinking of the sublingual gland. But there are many mucus secreting cells embedded in the epithelium of various tissues (such as intestinal tract, female reproductive tract, etc.)
A simple cuboidal epithelium absorbs and secretes. It produces mucous. It is found in the liver, thyroid, mammary, and salivary glands.
psuedostratified ciliated columnar epithelial cells and goblet cells
Mucous, made by mucous glands, stick to the cilia of cells that are found in the mucous membranes.
