   Q.Fill in the blank: The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining part of the Graafian follicle transform as ______.

   ›Reveal solutionSolution

   After ovulation, the ruptured Graafian follicle is converted into the corpus luteum, which secretes progesterone to maintain the uterine lining.

   The menstrual cycle has follicular, ovulatory and luteal phases. After ovulation (release of the ovum), the remaining part of the Graafian follicle transforms into the corpus luteum ('yellow body'), which secretes large amounts of …

   Q.The remaining part of Graafian follicle, after ovulation is termed as

   (a) Primary follicle

   (b) Stroma

   (c) Corpus albicans

   (d) Corpus luteum

   ›Reveal solutionSolution

   The empty Graafian follicle left behind after ovulation develops into the corpus luteum, a temporary progesterone-secreting endocrine structure.

   During the ovarian cycle, a mature Graafian follicle ruptures at ovulation to release the secondary oocyte. The remaining follicular cells (granulosa and theca cells) do not simply disappear — they reorganise into a yellowish glandular mass called the corpus luteum ('yellow body').

   • The corpus luteum secretes progesterone, which maintains the endometrium so it can support implantation.
   • If fertilisation occurs, hCG from the developing embryo keeps the corpus luteum active through early pregnancy. …

   Q.Which one is not a part of fallopian tube?

   (a) Isthmus

   (b) Ampulla

   (c) Infundibulum

   (d) Cervix

   ›Reveal solutionSolution

   The fallopian tube (oviduct) has three named regions — infundibulum, ampulla, and isthmus; the cervix belongs to the uterus, not the tube.

   Each fallopian tube extends from near the ovary to the uterus and is divided into distinct regions:

   • Infundibulum — the funnel-shaped end near the ovary, fringed with finger-like projections (fimbriae) that help sweep the released ovum into the tube.
   • Ampulla — the wider, longer middle part of the tube; this is typically where fertilisation occurs. …

   Q.Given below are few statements with reference to the uterus in the female reproductive system :

   (i) The myometrium exhibits strong contractions during the delivery of the baby.

   (ii) The uterus opens into the cervix through a narrow opening called vagina.

   (iii) The cavity of the cervix and the vagina forms the birth canal.

   (iv) The outermost layer of uterus is a thin membranous perimetrium.

   (v) The uterus is supported by tendons attached to the pelvic wall. Choose the option with all true statements from the given options : (A) (i),

   (ii) and

   (iv) (B) (ii),

   (iii) and

   (v) (C) (ii),

   (iv) and

   (v) (D) (i),

   (iii) and (iv)

   ›Reveal solutionSolution

   The question tests knowledge of uterine anatomy and function. Statements (i), (iii), and (iv) are correct; (ii) and (v) are false. The correct option is (D).

   The uterus is a pear-shaped, hollow muscular organ in the female pelvis. Its structure and function are frequently tested in biology exams, especially the layers of the uterine wall and the birth canal. Let’s examine each statement carefully.

   1. Statement (i): "The myometrium exhibits strong contractions during the delivery of the baby."

      The uterine wall has three layers: the inner endometrium, the middle myometrium, and the outer perimetrium. The myometrium is composed of smooth muscle fibres. During labour, these muscles contract rhythmically and powerfully to push the baby out through the birth canal. This statement is true.

   2. Statement (ii): "The uterus opens into the cervix through a narrow opening called vagina."

      This statement gets the anatomical order wrong. The uterus opens into the cervix, not the other way around. The cervix is the lower, narrow part of the uterus that projects into the vagina. The opening between the uterus and the cervix is called the internal os, and the cervix then opens into the vagina through the external os. The vagina is a separate canal, not a "narrow opening" connecting uterus to cervix. This statement is false.

   3. Statement (iii): "The cavity of the cervix and the vagina forms the birth canal."

      During childbirth, the baby passes from the uterus through the cervix (which dilates) and then through the vagina. Together, the cervical canal and the vaginal canal constitute the birth canal. This statement is true.

   4. Statement (iv): "The outermost layer of uterus is a thin membranous perimetrium."

      The perimetrium is indeed the outermost serous layer of the uterus. It is a thin membrane derived from the peritoneum. This statement is true.

   5. Statement (v): "The uterus is supported by tendons attached to the pelvic wall." …

   Q.What is the fate of corpus luteum if fertilization does not occur?

   (a) Corpus striatum

   (b) Corpus callosum

   (c) Corpus spongiosum

   (d) Corpus albicans

   ›Reveal solutionSolution

   Without fertilization, the corpus luteum regresses into the corpus albicans and progesterone secretion stops, triggering menstruation.

   After ovulation, the ruptured Graafian follicle is transformed by LH into the corpus luteum, which secretes progesterone to maintain the uterine endometrium for a possible pregnancy. If the released ovum is not fertilized, the corpus luteum has a limited lifespan (about 10-14 days); it degenerates into a small, fibrous, whitish mass of scar tissue called the corpus albicans. As the corpus luteum regresses, progesterone levels fall sharply, which cau …

   Q.Fill in the blank: Graafian follicles are found in ______ organ of human body.

   ›Reveal solutionSolution

   Graafian follicles - the mature, fluid-filled ovarian follicles that release the ovum at ovulation - are located in the ovary.

   Inside each ovary, primary follicles present at birth develop, under hormonal (FSH/LH) stimulation beginning at puberty, into secondary and then tertiary follicles. The tertiary follicle further matures into the Graafian follicle, a large, fluid-filled follicle in which the secondary oocyte is surrounded by the zona pe …

   Q.Which of the following structures is characterised by the presence of a fluid filled cavity called antrum?

   (a) Primary follicle

   (b) Secondary follicle

   (c) Tertiary follicle

   (d) Corpus luteum

   ›Reveal solutionSolution

   As a primary follicle matures into a secondary and then a tertiary follicle, a fluid-filled cavity called the antrum develops within it, and it is fully formed by the tertiary follicle stage.

   Follicular development in the ovary proceeds: primordial follicle -> primary follicle -> secondary follicle -> tertiary follicle -> Graafian follicle. The tertiary follicle is distinguished by a well-developed, fluid-filled cavity called the antrum, along with a thecal layer differentiated into theca inte …

   Q.Fill in the blank: The inner glandular layer of uterus is called ______.

   ›Reveal solutionSolution

   The endometrium is the inner, glandular, highly vascular lining of the uterus that undergoes cyclic changes and is where the embryo implants.

   The wall of the uterus has three layers: the outer perimetrium, the middle thick muscular myometrium (responsible for uterine contractions during parturition), and the innermost endometrium, which is glandular and richly supplied with blood vessels. The endometrium undergoes cyclical changes th …

    Q.If fertilization does not occur, Graafian follicle is converted to which endocrine gland?

    (a) Corpus luteum

    (b) Corpus albicans

    (c) Corpus spongiosum

    (d) Corpus cavernosum

    ›Reveal solutionSolution

    After ovulation, the ruptured Graafian follicle transforms into the corpus luteum, a temporary endocrine gland that secretes progesterone; if fertilisation/implantation does not occur, the corpus luteum itself later degenerates into a non-functional scar tissue called the corpus albicans.

    During the ovarian cycle, after ovulation (release of the secondary oocyte), the remaining follicular tissue of the ruptured Graafian follicle in the ovary is reorganised into a solid, glandular structure called the corpus luteum ('yellow body'). The corpus luteum is a true (though temporary) endocrine gland - it secretes large amounts of progesterone, which is essential for maintaining the endometrium (uterine lining) in a receptive state for implantation.

    • If fertilisation and implantation do occur, the corpus luteum is maintained (initially under hCG signalling from the developing embryo) and continues secreting progesterone throughout early pregnancy. …

    The human menstrual cycle (ovarian cycle) has an average length of about 28 days, running from the start of one menstruation to the start of the next.

    The menstrual cycle, also called the ovarian cycle, is the recurring reproductive cycle in human females that lasts, on average, about 28 days. It comprises the menstrual phase (shedding of the uterine lining), the follicular/proliferative phase (follicle maturation, rising oestrogen, endometrial thickening), ovulation (release of the ovum around day 14), and the luteal/secretory phase (cor …
