  2. Foveola - Wikipedia

    en.wikipedia.org/wiki/Foveola

    Foveola. 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 ] In this region the cone receptors are found to be longer ...

  3. Foveolar cell - Wikipedia

    en.wikipedia.org/wiki/Foveolar_cell

    Foveolar cells or surface mucous cells are mucus -producing cells which cover the inside of the stomach, protecting it from the corrosive nature of gastric acid. [1][a] These cells line the gastric mucosa and the gastric pits. Mucous neck cells are found in the necks of the gastric glands. The mucus-secreting cells of the stomach can be ...

  4. Gastric glands - Wikipedia

    en.wikipedia.org/wiki/Gastric_glands

    Gastric glands are glands in the lining of the stomach that play an essential role in the process of digestion. Their secretions make up the digestive gastric juice. The gastric glands open into gastric pits in the mucosa. The gastric mucosa is covered in surface mucous cells that produce the mucus necessary to protect the stomach's epithelial ...

  5. Gastric mucosa - Wikipedia

    en.wikipedia.org/wiki/Gastric_mucosa

    The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm thick, and its surface is smooth, soft, and velvety. It consists of simple secretory columnar epithelium, an underlying supportive layer of loose connective tissue called the lamina ...

  6. Psychotria viridis - Wikipedia

    The foveolae (also called domatia) are distinctive for Psychotria viridis and a few related species: They are generally 1.5–5 mm (0.059–0.197 in) long and 0.5–1 mm (0.020–0.039 in) wide at the top, conical and tapered to a closed base, open and truncate or variously ornamented at the top, and situated along the sides of the central vein ...

  7. Gastric pits - Wikipedia

    en.wikipedia.org/wiki/Gastric_pits

    2918. FMA. 76583. Anatomical terminology. [edit on Wikidata] Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands. [1][2] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium.

  8. Arachnoid granulation - Wikipedia

    en.wikipedia.org/wiki/Arachnoid_granulation

    Arachnoid granulations (also arachnoid villi, and pacchionian granulations or bodies) are small outpouchings of the arachnoid mater and subarachnoid space into the dural venous sinuses of the brain. The granulations are thought to mediate the draining of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system.
