The angular incisure (or angular notch) is a small notch on the stomach. It is located on the lesser curvature of the stomach near the pyloric end. Its location varies depending on how distended the stomach is.

With fundus photography, a special fundus camera points through the pupil to the back of the eye and takes pictures. These pictures help your eye doctor to find, watch and treat disease.

What are the layers of the fovea?

The foveal pit now contains a very thin, only one layer thick, ganglion cell layer, a thin inner plexiform layer (IPL) but a prominent inner nuclear layer (INL) (Figure 10, a). The cones are now evident as straight vertical cones with synaptic pedicles, cell bodies and inner segments.

What does foveolar hyperplasia mean?

Foveolar hyperplasia was defined as the presence of abnormal branching and twisting and at least a twofold elongation of gastric cardiac foveolae and pits.

Is chronic gastritis permanent?

A: Chronic gastritis caused by H. pylori bacteria or by use of NSAIDs or alcohol can be cured by either eliminating the bacteria or discontinuing use of the substance. However, if a person has had chronic gastritis for a long time, some of the damage to the inner stomach lining may be permanent.

What are the 3 parts of the stomach?

The stomach has three anatomical regions:

  • cardiac, which contains mucous secreting glands (called cardiac glands) and is closest to the oesophagus.
  • 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 gastric fundus?

Fundus: the upper part of the stomach next to the cardia. Body (corpus): the main part of the stomach, between the upper and lower parts.

How is the normal fundus used to identify the eye?

Normal Fundus The first task is to identify which eye is in the photograph. In order to do this, imagine yourself looking at the patient: the optic disc (the optic nerve) is always on the same side as the nose. On this photograph, the optic disc is on the left, meaning that this is a photograph of the left eye.

The left image (right eye) shows lighter areas close to larger vessels, which has been regarded as a normal finding in younger people. A fundus photo, showing the optic disc as a bright area on the right where blood vessels converge.

When do pepsinogen granules appear in the stomach?

It has been reported that the moment of the first appearance of measurable pepsinogen in the fetal stomach varies considerably between species. In the human fetus, granules appear in the peptic cells at weeks 32 to 36.

Are there any disease or pathology in the fundus?

Fundus (eye) Each fundus has no sign of disease or pathology. The gaze is into the camera, so in each picture the macula is in the center of the image, and the optic disc is located towards the nose. Both optic discs have some pigmentation at the perimeter of the lateral side, which is considered non-pathological.

What is the main function of the fundus? The fundus plays an important role, because it stores both undigested food and gases that are released during the process of chemical digestion.
