Surface linings of the body, which secrete mucus.
Membrane lining passages and cavities communicating with the air.
A wet membrane which lines internal passages in the body, e.g. the nose, mouth, stomach and throat, and secretes mucus.
Thin sheet of tissue that covers or lines parts of the body; it consists of a layer of epithelium overlying thicker connective tissue. It protects underlying organs, secretes mucus, and absorbs water and solutes. Also called mucosa.
A thin, soft tissue (found throughout the body) that lines a body cavity, passageway, or structure. A mucous membrane secretes mucus, a thick fluid that lubricates the tissue.
The moist membrane lining many tubular structures and cavities, including the nasal sinuses, respiratory tract, gastrointestinal tract, biliary, and pancreatic systems. The mucous membrane consists of a surface layer of epithelium, which contains glands secreting mucus, with underlying layers of connective tissue (lamina propria) and muscularis mucosae, which forms the inner boundary of the mucous membrane.
The membrane lining passages and cavities communicating with the air, consisting of a surface layer of epithelium, a basement membrane, and an underlying layer of connective tissue (lamina propria). Mucus-secreting cells or glands are usually present in the epithelium but may be absent. In humans, mucous membranes and the skin provide effective mechanisms for preventing the entry of pathogens. Mucous membranes are normally colonized with nonpathogenic organisms that discourage colonization by pathogens because the resident organisms compete for the nutrients essential to their survival. Some mucosal surfaces in the digestive tract have special characteristics that tend to repel or kill organisms, such as the extremely high acid level on the mucosa of the stomach.
The moist membrane lining many body cavities and passages, including the respiratory and digestive tracts.
The moist tissue that lines some organs and body cavities (such as the nose, mouth and lungs) and makes mucus.
The moist, protective lining that covers some of the openings to the body and the air passages.
The soft, pink tissue that lines most of the cavities and tubes in the body, including the respiratory system, gastrointestinal tract and genitourinary tracts, and the eyelids.
A membrane abundant in mucous glands, which coats body passages and cavities that directly or indirectly connect with the external environment. Examples include the alimentary, respiratory, and genitourinary tracts. Mucous membranes serve various functions such as protection, support, absorption of nutrients, and the secretion of mucus, enzymes, and salts.
The gentle, rosy, skin-resembling layer that coats numerous cavities and passages within the body, encompassing the respiratory and digestive tracts. Mucous membranes house specialized cells known as goblet cells, responsible for producing a liquid containing mucus.
Lining of passages and cavities in the body that are connected to the air.
