mucous cells
Skin and mucous membranes
The tissue at the entrance of the oropharynx is primarily composed of mucous membrane, which is a type of tissue that lines the cavity of the mouth and throat. This mucous membrane helps to protect and lubricate the tissues in the oropharynx, as well as assist in the process of swallowing and speech.
Mostly the mucous tissue in the respiratory system, but mucous tissue in the gastrointestinal system is also affected.
Chlamydia prefers to infect a type of tissue called columnar epithelium. This tissue is found in mucous membranes, but not on the external skin.
A mucous membrane
Any body area that has an outlet to the out side is covered in a mucous membrane: respiratory tact. digestive tract, urinary tract, even the membrane that surrounds the orbit of the eye (eye ball).
Mucous tissue is the membranes that line the structures and tracts of the body. Examples of this are in the nose, stomach and intestines, urinary bladder, mouth and eyelids.
The membranes that line body cavities open to the exterior are called mucous membranes. They are made up of epithelial tissue and are found in areas like the respiratory, digestive, and reproductive tracts. Mucous membranes help protect the body by secreting mucus and trapping pathogens.
mucoid connective tissue (Wharton jelly)areolar (?)
No, mucus is not a muscle but a secretion in epithelial tissue.
The innermost layer of the stomach is made of mucous membrane. The mucous membrane of the stomach contains simple columnar epithelium tissue, that has many exocrine cells.
Well for the sake of giving a good answer to an interesting question: oddly enough, I'd say yes. Influenza viruses attack our bodies by attaching to the specific cells of our mucous tissue. This type of tissue is in the lining of the respiratory system and also in the lining of the gastrointestinal system. So, it is possible to catch the flu if the virus gets on your mucous tissue regardless of where it is in your body. So, since the rectum is also lined with this type of tissue, it is possible (although unlikely) for a virus particle to enter into your gastrointestinal system at the top and not attach to the mucous tissue cells until it gets to the bottom and then manages to attach to one before it is excreted. In that sense, you would have flu virus particles attached to the cells of your mucous tissue in your rectum. And that could be considered having flu in your rectum. Alternately, if you had the virus on your hand (or an object) and if that managed somehow to touch the mucous tissue at your anus, then virus particles could be introduced and attach directly to the mucous tissue of the rectum near the anus, and then you could also have flu in your rectum. The symptoms would still be of the respiratory flu, not the "stomach flu" (gastroenteritis), however. It is the kind of virus that determines the symptoms, not the location of the introduction of the virus.
