Overexpression of the mucin proteins, especially MUC1, is associated with many types of cancer. [ 5 ] [ 6 ] Although some mucins are membrane -bound due to the presence of a hydrophobic membrane-spanning domain that favors retention in the plasma membrane , most mucins are secreted as principal components of mucus by mucous membranes or are ...
They secrete mucus to lubricate the vagina. [3] They are homologous to bulbourethral glands in males. However, while Bartholin's glands are located in the superficial perineal pouch in females, bulbourethral glands are located in the deep perineal pouch in males. Their duct length is 1.5 to 2.0 cm and they open into navicular fossa. [2]
Plasma from the vaginal walls due to vascular engorgement is considered to be the chief lubrication source, and the Bartholin's glands, located slightly below and to the left and right of the introitus (vaginal opening), also secrete mucus to augment vaginal wall secretions. Near ovulation, cervical mucus provides additional lubrication.
Estrogens and progestins are metabolized in the liver, so there is a theoretical concern for use in women with liver disease. [35] Large studies have shown a slight increased incidence of breast cancer among hormonal contraceptive users compared to nonusers. [36] However, the overall risk of breast cancer in users and nonusers remains low. [36]
The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. [1] The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. [2] [3]

Normal vaginal discharge is composed of cervical mucus, vaginal fluid, shedding vaginal and cervical cells, and bacteria. [1] The majority of the liquid in vaginal discharge is mucus produced by glands of the cervix. [1] [4] The rest is made up of transudate from the vaginal walls and secretions from glands (Skene's and Bartholin's). [4]
“These are great to moisten and loosen up hard mucus so it blows out easier,” Dr. Parikh says. In fact, Dr. Kelley calls salt water irrigation the “gold-standard intervention” for nasal ...
