Question

Lower narrow end of uterus is called as
A. Urethra
B. Cervix
C. Clitoris
D. Vulva

Answer 1

A hollow muscular organ located in the female pelvis between the rectum and bladder is called a uterus. The cervix is the part of the female reproductive system. It connects the uterus to the vagina.

Complete answer:
The cervix is a cylinder shaped part of the female reproductive system. It connects the vagina with the uterus. It is located at the lower part of the uterus and provides a passage between the uterine cavity and vaginal cavity. It is the narrow end of the uterus. The cervix is only about four centimeters (1.6 inches) long. The vagina is fused obliquely and circumferentially around the distal part of the cervix, dividing it into a lower, upper and supravaginal vaginal portion. The normal position of the cervix is slightly angulated downward and backward. It projects about two centimeters into the upper vaginal cavity. It is composed of fibro muscular tissue. There are two parts of cervix, endocervix and ectocervix. The inner part of the cervix lining the canal leading into the uterus is called endocervix. The outer part of the cervix is known as the ectocervix (exocervix). It is rounded and lip-like in shape and sticks out into the vagina.

The endocervical canal transports sperm into the uterine cavity, allows blood to flow from the uterus during menstruation, and it supplies mucus (a thick lubricating protein) to the female reproductive tract.

Hence, the correct answer is option (B).

Note: During childbirth, the cervix dilates to a great extent to allow the baby to pass through. The cervix opens a small amount to permit passage of menstrual flow during menstruation.
