Question
Which duct is the terminal excretory duct formed by the merger of the striated ducts in intraepithelial glands
Solution 1
The terminal excretory duct formed by the merger of the striated ducts in intraepithelial glands is known as the intercalated duct. Here are the steps:
-
Intraepithelial glands, also known as exocrine glands, are glands that secrete substances onto an epithelial surface by way of a duct.
-
These glands have a system of ducts that transport the secretions from the gland to the target surface. The system usually starts with smaller ducts merging into larger ones.
-
The smallest ducts, which are in direct contact with the glandular cells, are known as the intercalated ducts.
-
The intercalated ducts then merge to form the striated ducts. The striated ducts are named for their appearance under a microscope, which is due to the presence of mitochondria and infoldings of the plasma membrane.
-
The striated ducts then merge to form the interlobular ducts, which eventually drain the gland's secretions to the surface of the epithelium.
-
Therefore, the terminal excretory duct formed by the merger of the striated ducts in intraepithelial glands is the intercalated duct.
