Labia are the lips or folds of skin that sit on either what is normal sex of the vaginal opening. You might call them flaps or lips.
The Labia Library is about showing you that, just like any other part of the body, labia come in all shapes and sizes. They’re also really important in sex and they keep your vagina healthy. Health Victoria has developed The Labia Library to bust a few common myths about how normal labia look. Check out our Tumblr and Facebook pages for fantastic comments we’ve received about The Labia Library. Photographs are reproduced with kind permission from Show Off Books. The glands are located in and around the mouth and throat. The major salivary glands are called the parotid, submandibular and sublingual glands.
They all secrete saliva into the mouth: the parotid through ducts near the upper teeth, submandibular into the front portion under the tongue, and the sublingual through multiple ducts in the floor of the mouth. Salivary glands produce the saliva used to moisten your mouth, initiate digestion, and help protect teeth from decay. Obstruction to the flow of saliva most commonly occurs in the parotid and submandibular glands, usually due to stone formation. Saliva production is initiated, but cannot exit the ductal system, leading to swelling of the involved gland and significant pain, sometimes with an infection. Secondary infection of salivary glands from adjacent lymph nodes also occurs.
These lymph nodes are the glands in the upper neck which often become tender during a common sore throat Many of these lymph nodes are actually located on, within, and deep in the substance of the parotid gland, near the submandibular glands. When these lymph nodes enlarge through infection, this is noticed by the patient as a red, painful swelling in the area of the parotid or submandibular glands. If stones are not totally obstructive, the major glands will swell during eating and then gradually subside after eating, only to enlarge again at the next meal. Infection often develops in the abnormally pooled saliva, leading to more severe pain and swelling in the glands. If untreated long enough, the glands may become abscessed.
In some individuals the duct system of the major salivary glands may be abnormal. These ducts can develop small constrictions which decrease salivary flow, leading to infection and obstructive symptoms. The most common salivary gland infection is mumps, which involves the parotid glands. While this is most common in children, it can occur in adults. However if an adult has swelling in the area of the parotid gland on one side, it is more likely due to an obstruction or a tumor. Infections occurring because of ductal obstruction or sluggish flow of saliva have already been mentioned.
