Question

Mark the CORRECT sequence of structures in the breast from inner to outer side.

• A. Lactiferous ducts $\rightarrow$ Lactiferous sinuses $\rightarrow$ Lactiferous glands
• B. Lactiferous sinuses $\rightarrow$ Lactiferous ducts $\rightarrow$ Lactiferous glands
• C. Lactiferous glands $\rightarrow$ Lactiferous sinuses $\rightarrow$ Lactiferous ducts
• D. Lactiferous glands $\rightarrow$ Lactiferous ducts $\rightarrow$ Lactiferous sinuses

Hint:

Milk pathway: {Glands → Ducts → Sinuses → Nipple}.

Answer 1

The Correct Option is D

Step 1: Understand milk production.
Milk is produced in the lactiferous glands of the mammary glands.
Step 2: Trace the pathway of milk.
From lactiferous glands, milk flows into lactiferous ducts.
Step 3: Storage before release.
The ducts open into lactiferous sinuses, where milk is temporarily stored before release through nipple.
Step 4: Final sequence.
Thus, the correct inner-to-outer sequence is glands $\rightarrow$ ducts $\rightarrow$ sinuses.
