7. Nipple has 15-25 openings called ________________
a) Lactiferous ducts
b) Somniferous duct
c) Milk duct
d) Pores
View Answer
Explanation: Lactiferous ducts converge and form a branched system connecting nipple to the lobules of the mammary gland. Each breast has about 15-20 Lactiferous ducts.
8. The base of nipple is called the areola.
a) True
b) False
View Answer
Explanation: The base of the nipple is termed as areola. Milk comes out of nipple after child birth.
9. Which of the following is not the characteristic of mammary gland?
