The '''mucous membranes''' (or '''mucosae'''; singular '''mucosa''') are linings of mostly [[germ layer|endodermal]] origin, covered in [[epithelium]], which are involved in [[absorption (digestive)|absorption]] and [[secretion]]. They line various body cavities that are exposed to the external environment and internal [[organ (anatomy)|organs]]. It is at several places continuous with [[skin]]: at the [[nostril]]s, the [[lip]]s, the [[ear]]s, the [[Sex organ|genital area]], and the [[anus]]. The sticky, thick fluid secreted by the mucous membranes and [[glands|gland]] is termed [[mucus]]. The term ''mucous membrane'' refers to where they are found in the [[body]] and not every mucous membrane secretes mucus. |
|||
Body cavities featuring mucous membrane include most of the [[respiratory system]]. The [[glans penis]] (head of the [[penis]]) and [[glans clitoridis]], along with the inside of the [[prepuce]] (foreskin) and the [[clitoral hood]], are mucous membranes. The urethra is also a mucous membrane. The secreted mucus traps the pathogens in the body, preventing any further activities of diseases. |
