Question: 162: Arrange the components of mammary gland. (from proximal to distal)
(a) Mammary duct
(b) Lactiferous duct
(c) Alveoll
(d) Mammary ampulla
(e) Mammary tubules
Choose the most appropriate answer from the options given below :
(1) (c) → (a) → (d) → (e) → (b)
(2) (b) \rightarrow (c) \rightarrow (e) \rightarrow (d) \rightarrow (a)
(3) (c) → (e) → (a) → (d) → (b)
(4) ( e ) \rightarrow (c) \rightarrow (d) \rightarrow (b) \rightarrow (a)
Answer: Option (3)
Explanation:
The mammary gland is made up of glandular tissue organized for the production and transport of milk.
The alveoli are the secretory units of the mammary gland where milk is synthesized,
so they are the most proximal components.
Alveoli open into mammary tubules, which collect the milk produced.
Several mammary tubules join to form mammary ducts that carry milk further.
The mammary ducts widen to form the mammary ampulla,
which acts as a temporary storage area.
Finally, milk is transported through the lactiferous duct to the nipple.
Thus, the correct proximal to distal sequence is (c) → (e) → (a) → (d) → (b).
