Statement I: The myometrium is the inner glandular layer of the uterus that undergoes cyclical changes during the menstrual cycle.

Statement II: The cervix is the narrow inferior portion of the uterus that opens into the vagina, and its canal forms part of the birth canal along with the vagina.

Only Statement II  is correct .

The correct answer is Option (4) –Only Statement II  is correct .

The female reproductive system consists of a pair of ovaries alongwith a pair of oviducts, uterus, cervix, vagina and the external genitalia located in pelvic region. These parts of the system alongwith a pair of the mammary glands are integrated structurally and functionally to support the processes of ovulation, fertilisation, pregnancy, birth and child care.

The oviducts (fallopian tubes), uterus and vagina constitute the female accessory ducts. The uterus is single and it is also called womb. The shape of the uterus is like an inverted pear. It is supported by ligaments attached to the pelvic wall. The uterus opens into vagina through a narrow cervix. The cavity of the cervix is called cervical canal which along with vagina forms the birth canal. The wall of the uterus has three layers of tissue. The external thin membranous perimetrium, middle thick layer of smooth muscle, myometrium and inner glandular layer called endometrium that lines the uterine cavity. The endometrium undergoes cyclical changes during menstrual cycle while the myometrium exhibits strong contraction during delivery of the baby.
