What is gastric fundus?
The fundus refers to the superior portion of the stomach that lies above an imaginary horizontal plane that passes through the esophagogastric junction. The antrum is the smaller distal, one-fourth to one-third of the stomach. The narrow, 12-cm channel that connects the stomach and duodenum is the pylorus.
What is fundus in endoscopy?
In the fundus can be seen the lesser curvature. Just beyond the antrum is the pylorus emptying into the first portion of duodenum is at the lower right. The normal appearance of the gastric fundus on upper GI endoscopy is shown below at the left, with the normal duodenal appearance at the right.
What is the function of fundus of the stomach?
Fundus. The fundus stores gas produced during digestion. It typically doesn’t store any food; however, it can if the stomach is very full.
Is the gastric fundus in the stomach?
fundus, the body or largest part of the stomach which contain the gastric (fundic) glands. pyloric, which secretes two types of mucus, and the hormone gastrin.
Where is the gastric fundus located?

What is a gastric lesion?
Gastric lesions include crypt dilatation, submucosal fibrosis, adenomatous gastric hyperplasia, mineralization, and erosion or ulceration. Gastric ulcers may be stress-related, especially in mice with prolonged illness. Germfree mice may have reduced muscle tone in the intestinal tract.
What diseases can be detected by an endoscopy?
Upper GI endoscopy can be used to identify many different diseases:
- gastroesophageal reflux disease.
- ulcers.
- cancer link.
- inflammation, or swelling.
- precancerous abnormalities such as Barrett’s esophagus.
- celiac disease.
- strictures or narrowing of the esophagus.
- blockages.
Why is it called fundus of stomach?

What liquid is in the stomach?
The main exocrine product of the stomach is gastric juice a mixture of mucus, hydrochloric acid, and digestive enzymes. Gastric juice is mixed with food in the stomach to promote digestion.
What is gastric cardia?
The gastric cardia is a microscopic zone that is normally found in the most proximal portion of the stomach, although cardiac-type mucosa may arise in the distal esophagus as a metaplastic phenomenon secondary to gastroesophageal reflux disease (GERD).
What are the 3 types of gastric glands?
There are three types of gastric glands, distinguished from one another by location and type of secretion. The cardiac gastric glands are located at the very beginning of the stomach; the intermediate, or true, gastric glands in the central stomach areas; and the pyloric glands in the terminal stomach portion.
Why gastric juice doesn’t destroy the stomach cells?
Second, HCl in the lumen doesnt digest the mucosa because goblet cells in the mucosa secrete large quantities of protective mucus that line the mucosal surface. Basic electrolytes, such as HCO3 –, trapped inside the layer of mucus neutralize any HCl that penetrates the mucus.
What’s the cause of gastritis?
Stomach and pyloric valve The inflammation of gastritis is most often the result of infection with the same bacterium that causes most stomach ulcers. Regular use of certain pain relievers and drinking too much alcohol also can contribute to gastritis.
Can stomach lesions be cured?
Q: Can an ulcer be completely cured? A: If you have peptic ulcer disease, which can involve stomach ulcers and/or duodenal ulcers of the small intestine, the answer is yes! These ulcers can be completely healed.
What is gastric antrum inflammation?
Antral gastritis is an inflammation of the antral portion of the stomach of unknown etiology, which probably begins in the mucosa, usually involves the submucosa, and may even extend to the serosa.
What is a gastric mass?
A stomach mass is a lump or growth in the stomach area. A person may be able to feel the lump, or it might be deeper in the stomach. Stomach masses have many possible causes, and some may only be detectable with imaging or surgical exploration.
Can you choke during an endoscopy?
The endoscope camera is very slim and slippery and will slide pass the throat into the food pipe (oesophagus) easily without any blockage to the airways or choking. There is no obstruction to breathing during the procedure, and patients breathe normally throughout the examination.
Which is better CT scan or endoscopy?
Both procedures are relatively safe; CT does expose you to radiation (at a safe level) and if IV contrast dye is used to enhance CT images, some people may be allergic or have the possibility of kidney damage while endoscopy has the risk of bowel perforation and allergic reaction to anesthesia drugs.
What type of cancers can an endoscopy detect?
This procedure is used to check for stomach cancer. An upper endoscopycalled endoscopic gastroduodenoscopy (EGD)is a procedure that helps find most stomach cancers. During this test, a doctor looks inside your stomach with a thin, lighted tube called an endoscope.
What is pH of gastric juice?
The normal volume of the stomach fluid is 20 to 100 mL and the pH is acidic (1.5 to 3.5).
What is the stomach lining called?
Your stomach has a protective lining of mucus called the mucosa. This lining protects your stomach from the strong stomach acid that digests food. When something damages or weakens this protective lining, the mucosa becomes inflamed, causing gastritis. A type of bacteria called Helicobacter pylori (H.
What are the 4 regions of the stomach?
The stomach is a ‘j’-shaped organ, with two openings- the oesophageal and the duodenal- and four regions- the cardia, fundus, body and pylorus.
What is a normal fundus?
Normal Fundus. The disk has sharp margins and is normal in color, with a small central cup. Arterioles and venules have normal color, sheen, and course. Background is in normal color. The macula is enclosed by arching temporal vessels. The fovea is located by a central pit.
Why fundus examination is done?
This test is often included in a routine eye exam to screen for eye diseases. Your eye doctor may also order it if you have a condition that affects your blood vessels, such as high blood pressure or diabetes. Ophthalmoscopy may also be called funduscopy or retinal examination.
How do I check my eye fundus?
Hold the instrument with the hand ipsilateral to the examining eye; both are ipsilateral to the eye being examined: examine every left fundus with your left eye, holding the ophthalmoscope in your left hand (Figure 117.2); and every right fundus with your right eye and hand.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
