Question

The main function of the fimbriae of the fallopian tube in females is to
A. Release the ovum from the Graafian follicle
B. Make necessary changes in the endometrium for implantation
C. Help in the development of corpus luteum
D. Help in the collection of the ovum after ovulation
E. Help in the development of ovary

Answer 1

Small, fingerlike cellular projections are usually present on the apical surfaces of the linings of internal hollow organs which assist in the movement of cells or secretions.

Complete answer:
Option (A) is incorrect: The production of Luteinizing hormone stimulates the ovaries to produce oestrogen and progesterone. It triggers the release of a mature ovum from the ovary by rupturing the Graafian follicle
Option (B) is incorrect: The secretion of Oestrogen hormone is responsible for the necessary changes that helps to develop a thickened uterine lining (endometrium) for the process of implantation.
Option (C) is incorrect: Luteinizing hormone (LH) triggers ovulation and develops corpus luteum from the remains of the Graafian follicle after ovulation.
Option (D) is correct: The fimbriae of the uterine tube, also called a fimbriae tube. A small, fringe of finger-like cellular projections and it is located at the end of the fallopian tube is known as fimbria.
During the ovulation period, when an egg is released from the ovary, the fimbriae help the non-motile egg to enter into the Fallopian tube, from which it moves through the passage to the uterus.
Its main function is to collect the egg released from the ovary after ovulation and draw it into the fallopian tube.

Hence, the correct answer is option (D).

Note: In women, the production of Luteinizing hormone (LH) by the anterior pituitary gland plays a predominant role before and after ovulation at the time of menstrual cycle. It helps to stimulate the other important hormones for sexual development and functioning.
