These glands are often referred to simply as the gastric glands.
The foveola is located within a region called the macula, a yellowish, cone photoreceptor filled portion of the human retina. Approximately 0.35 mm in diameter, the foveola lies in the center of the fovea and contains only cone cells and a cone-shaped zone of Müller cells . [ 1 ]
Reactive gastropathy, is characterized histologically by: [2] - Foveolar hyperplasia (black arrow), as a tortuosity in the "neck" region of the gastric glands. - Scant or minimal inflammatory cells (white arrow), i.e. lack of large numbers of neutrophils and plasma cells..
