(a) Corpus luteum: The ruptured Grafiaan follicle gives rise to a structure called the Corpus luteum. A hormone Progesterone hormone during the luteal phase of the menstrual cycle. The increased amount of progesterone inhibits the secretions of FSH and LH, thereby preventing ovulation. The proliferation of the endometrium of the uterus and the process of implantation is also allowed by the corpus luteum.
(b) Endometrium: The innermost lining of the uterus is the endometrium. It is removed during menstrual discharge each month in the menstrual cycle and thus it prepares itself for the implantation of the embryo.
(c) Acrosome: In the sperm, there is a cap-like structure present in the anterior part called the acrosome. There is a presence of an enzyme called hyaluronidase enzyme, which hydrolyses the outer membrane of the egg. The acrosome secretes enzymes that help in the penetration of sperm into the egg by dissolving the egg membrane during fertilization
(d) Sperm tail: It is the region of the sperm which is several times longer than the head. The locomotion of the sperm is determined inside the female reproductive tract by the tail of the sperm.
(e) Fimbriae: The finger-like projections at the ovarian end of the fallopian tube are called fimbriae. After the process of ovulation, they help in the collection of the ovum which is facilitated by the beating of the cilia.
