Question

Arrange in sequence the following in mammary gland:
a. Mammary tubule
b. Mammary Ampulla
c. Alveoli
d. Mammary duct
e. Lactiferous duct

• A. c, b, a, e, d
• B. c, a, d, b, e
• C. c, a, e, d, b
• D. c, b, d, a, e

Hint:

Remember: Alveoli secrete milk → Tubules → Ducts → Ampulla stores → Lactiferous duct releases.

Answer 1

The Correct Option is B

The correct flow of milk in the mammary gland begins from the site of secretion and ends at the point of ejection:
- Alveoli (c): These are the milk-secreting structures in the mammary gland.
- Mammary tubule (a): Milk secreted in alveoli is drained into mammary tubules.
- Mammary duct (d): These tubules join to form mammary ducts.
- Mammary ampulla (b): The ducts widen to form the ampulla, a storage region.
- Lactiferous duct (e): Finally, milk is transported through the lactiferous duct to the exterior.
Thus, the correct sequence is: c → a → d → b → e
