  2. Serous demilune - Wikipedia

    en.wikipedia.org/wiki/Serous_demilune

    After sectioning the serous cells resembled the common demilune shape, and were so named. [2] When the gland has this demilunar structure, it has mucoserous acini producing both serous and mucous secretions. Slice of submandibular gland. H&E staining, the structure of the red stained cytoplasm on the left is the serous demilunes.

  3. Mucoserous acinus - Wikipedia

    en.wikipedia.org/wiki/Mucoserous_acinus

    Mucoserous acini (singular acinus) or mixed acini are mainly present in submandibular and sublingual glands. They are formed by mucous cells with some serous cells interspersed each other. Both cells pour their secretion directly in the lumen. Layer of mucous cells and serous demilune of serous cells superficial to mucous cells

  4. Serous gland - Wikipedia

    en.wikipedia.org/wiki/Serous_gland

    They contain serous acini, a grouping of serous cells that secrete serous fluid, isotonic with blood plasma, that contains enzymes such as alpha-amylase. Serous glands are most common in the parotid gland and lacrimal gland but are also present in the submandibular gland and, to a far lesser extent, the sublingual gland .

  5. Mucous gland - Wikipedia

    en.wikipedia.org/wiki/Mucous_gland

    They produce a glycoprotein, mucin that absorbs water to form a sticky secretion called mucus. They are from 12 to 25 mm. long, and about 8 mm. broad, and each opens by three or four ducts on the under surface of the apex. The Weber's glands are an example of muciparous glands located along the tongue.

  6. Exocrine gland - Wikipedia

    en.wikipedia.org/wiki/Exocrine_gland

    Seromucous glands (mixed) secrete both protein and mucus. Examples include the salivary glands: although the parotid gland (saliva secretion 25%) is predominantly serous, the sublingual gland (saliva secretion 5%) mainly mucous gland, and the submandibular gland (saliva secretion 70%) is a mixed, mainly serous gland.

    Giuseppe Oronzo Giannuzzi. Giuseppe Oronzo Giannuzzi (March 16, 1838, Altamura, Kingdom of the Two Sicilies – March 8, 1876, Siena, Italy) was an Italian physiologist.. His most important discovery is one of the serous demilunes, or crescents: cellular formations that are on some submaxillary salivary glands.

  9. Salivary gland - Wikipedia

    en.wikipedia.org/wiki/Salivary_gland

    Each acinus consists of a single layer of cuboidal epithelial cells surrounding a lumen, a central opening where the saliva is deposited after being produced by the secretory cells. The three forms of acini are classified in terms of the type of epithelial cell present and the secretory product being produced - serous, mucoserous, and mucous.
