FUNDUS GLANDS Meaning and
Definition
-
Fundus glands are specialized glands located in the fundus region of the stomach, which is the upper portion of the organ. These glands secrete various substances that play crucial roles in the digestion process.
The fundus glands are composed of different types of cells, including parietal cells, chief cells, and mucous cells. Parietal cells secrete hydrochloric acid, which helps in the breakdown of food and destroys harmful bacteria that may have been ingested. They also produce intrinsic factor, a protein that is essential for the absorption of vitamin B12 in the small intestine.
Chief cells are responsible for producing pepsinogen, an inactive enzyme that is converted to pepsin in the presence of hydrochloric acid. Pepsin is a protease that aids in the digestion of proteins by breaking them down into smaller peptides.
Mucous cells secrete mucus, which forms a protective barrier on the surface of the stomach lining, preventing damage from the acidic environment and reducing friction between the stomach walls.
The secretions of the fundus glands, including hydrochloric acid, enzymes, and mucus, collectively contribute to the proper digestion of food in the stomach. These substances also help in the defense against pathogens by killing bacteria and other microbes that may have entered the stomach through food or drink. Overall, the fundus glands are essential for maintaining the normal function of the stomach and promoting efficient digestion.

Etymology of FUNDUS GLANDS
The word "fundus" is derived from the Latin term "fundus uteri", which translates to "the bottom of the uterus". It refers to the upper part of an organ, such as the stomach or uterus, that is farthest away from the opening. In the context of the gastrointestinal system, the fundus is the part of the stomach that lies above the level of the opening of the esophagus.
The term "glands" has its roots in the Latin word "glandula", which can be traced back to the Greek word "glándion". It refers to an organ or group of cells within an organ that produces substances such as hormones or enzymes.
