Question

Which of the following is NOT a characteristic feature of the mammary gland?

• A. There are many plasma cells in the connective tissue surrounding the epithelial units.
• B. An apocrine secretion of lipids occurs into the breast milk.
• C. There are striated ducts that are active in transport of ions and water.
• D. Mammary gland responds to steroid and peptide hormones.

Answer 1

The correct option is C There are striated ducts that are active in transport of ions and water.

• The mammary gland is exocrine gland is enlarged and modified sweat glands and are the characteristic of mammals which gave the class its name.
• The basic components of the mammary gland are the alveoli lined with milk-secreting cuboidal cells and surrounded by myoepithelial cells. The cells typically exhibit apocrine secretion.
• The mammary glands are responsible for lactation, or the production of milk. They also respond to steroid and peptide hormones. Hence, There are striated ducts that are active in the transport of ions and water is NOT a characteristic feature of the mammary gland.
So, the correct answer is 'There are striated ducts that are active in the transport of ions and water'.
