Question

Nature of mammary gland is .......

• A. Apocrine
• B. Merocrine
• C. Holocrine
• D. All of the above

Answer 1

The correct option is A Apocrine

• Apocrine gland cells secrete their secretions in the form of pinched-off buds or vesicles into the lumen of the gland. Mammary gland is an example of an apocrine gland.
• Merocrine glands are those glands in which cells secrete their substances by exocytosis from secretory cells into an epithelial walled duct or ducts and thence onto a bodily surface or into the lumen. Salivary glands are merocrine in nature.
• Holocrine glands are those glands whose secretions are produced in the cytoplasm of the cells and these are released by the rupture of the plasma membrane. Sebaceous gland is a holocrine gland.
• So, the correct answer is option A.
