3. _________ lies between external opening to vagina and internal opening to uterus.
a) Lateral cervical ligaments
b) Round ligaments
c) Cervical canal
d) Mesometrium
View Answer
Explanation: Cervical canal is sindle shaped flattened canal of the cervix. It is seen in neck of uterus. It is also called as canal of the cervix.
4. Where does implantation of the blastocyst occur?
a) Fallopian tube
b) Endometrium
c) Ovary

5. Which hormones thicken the lining of the uterus?
a) FSH
b) Estrogen
c) LH
d) Progesterone
View Answer
Explanation: Estrogen is the primary female sex hormone. It is responsible for development of female reproductive system and regulation of secondary sex characteristics.
6. The contraction of the myoepithelial breast cells is stimulated by ____________
a) Estrogen
b) Progesterone
c) Oxytocin
d) Prolactin
View Answer
Explanation: Prolactin is luteotrophic hormone. It helps to produce milk after childbirth. It is important for female reproductive health.
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?
a) There are many plasma cells in the connective tissue surrounding epithelial units
b) There is apocrine secretion of lipids in Brest milk
c) Mammary gland is responsive for both hormones and steroids.
d) There are striated ducts that are active in transport of ions and water
View Answer
Explanation: Striated ducts are found in salivary glands. Breast doesn’t have striated ducts. Breasts have stratified cuboidal epithelium.
10. A non lactating mammary gland in adult female cannot produce ilk because of the lack of which of the following?

b) Lactiferous sinuses
c) Intraovular ducts
d) Alveoli
View Answer
Explanation: Functional alveoli is absent in non lactating adult female. Hence component of breast milk cannot be synthesized.
