To identify the structure that is not an accessory duct of the female reproductive system, one must first define accessory ducts. Accessory ducts in this system facilitate the movement and provision of support for the ovum and subsequent zygote, playing a vital role in reproduction.
Let's examine each option:
Consequently, the Uterus is not considered an accessory duct of the female reproductive system due to its principal function of supporting fetal development, rather than serving as a conduit for gametes or fertilized eggs. Thus, the correct identification is the Uterus.
The female external genitalia encompass the structures forming the external reproductive anatomy. The following options are presented:
Accordingly, the components of the female external genitalia are:
Therefore, the correct response includes only (A), (B), and (D).
The correct answer is Ovary. The ovary is not the destination for sperm during coitus. Sperm navigates the female reproductive tract as follows: sperm enters the vagina and proceeds through the Cervix, then enters the Uterus, and finally reaches the Fallopian Tube, where fertilization typically occurs. The Ovary produces and releases the ovum during ovulation but is not a point of sperm transport.
The human menstrual cycle consists of hormonal shifts and events. Key phases and activities are as follows:
Consequently, the event "the corpus luteum secretes large amounts of progesterone" occurs post-ovulation, during the luteal phase, not before it.
| Option | Description |
|---|---|
| The secretion of LH and FSH increases during the follicular phase. | This occurs before ovulation. |
| The corpus luteum secretes large amounts of progesterone. | This occurs after ovulation. |
| LH and FSH attain peak levels in the middle of the cycle. | This marks the time of ovulation. |
| Maximum secretion of LH induces rupture of the Graafian follicle. | This occurs during ovulation. |
| List-I (Phase of menstrual cycle) | List-II (Days of menstrual cycle) |
| (A) Proliferative phase | (I) 14th day |
| (B) Menstrual phase | (II) 15th–28th/29th days |
| (C) Secretory phase | (III) 1st–5th days |
| (D) Ovulatory phase | (IV) 5th–13th days |
The human menstrual cycle comprises distinct phases, each defined by specific biological markers and hormonal fluctuations. To facilitate matching, each phase and its corresponding cycle days will be detailed.
Based on this information, the phases can be accurately matched with their respective cycle days:
| (A) Proliferative phase | (IV) 5th–13th days |
| (B) Menstrual phase | (III) 1st–5th days |
| (C) Secretory phase | (II) 15th–28th/29th days |
| (D) Ovulatory phase | (I) 14th day |
The correct matching is:
(A) - (IV), (B) - (III), (C) - (II), (D) - (I)
