a.
To explain:
Whether the first phrase in the pair that is the cell number in morula is greater than second phrase that is the cell number in gastrula or smaller or both are equal.
Concept introduction:
The gametogenesis is the process of formation of gametes. The female gamete is known as egg cell and the male gamete is known as the sperm. The fertilization is the process in which the male gamete fuses with the female gamete.
b.
To explain:
Whether the first phrase in the pair that is the thickness of endometrium after ovulation is greater than second phrase that is thickness of endometrium after menstruation or smaller or both are equal.
Concept introduction:
The gametogenesis is the process of formation of gametes. The female gamete is known as egg cell and the male gamete is known as the sperm. The fertilization is the process in which the male gamete fuses with the female gamete.
c.
To explain:
Whether the first phrase in the pair that is the number of eggs released from ovary during each ovarian cycle is greater than second phrase that is the number of sperms released during ejaculation or smaller or both are equal.
Concept introduction:
The gametogenesis is the process of formation of gametes. The female gamete is known as egg cell and the male gamete is known as the sperm. The fertilization is the process in which the male gamete fuses with the female gamete.
d.
To explain:
Whether the first phrase in the pair that is the number of chromosomes in egg
are greater than second phrase that is the number of chromosomes in a sperm cell or smaller or both are equal.
Concept introduction:
The gametogenesis is the process of formation of gametes. The female gamete is known as egg cell and the male gamete is known as the sperm. The fertilization is the process in which the male gamete fuses with the female gamete.

- In the fertility awareness method of birth control, a woman gauges her monthly fertile period by monitoring changes in the consistency of her vaginal mucus. What kind of information does such a method provide about the likelihood of getting pregnant?arrow_forwardWhich of the following statements correctly describes the development of the endometrium during the menstrual cycle? Select one: A. Estrogen causes accelerated development of the endometrium during the follicle stage and then maintains the thickness of the endometrium during the luteal stage. B. Progesterone causes the relatively slow development of the endometrium during the follicle stage and accelerates the thickening of the endometrium during the luteal stage. C. Estrogen causes the relatively fast thickening of the endometrium during the follicular stage. Progesterone maintains the thickness of the endometrium during the luteal phase. D. Estrogen causes the relatively slow development of the endometrium during the follicular stage. Progesterone causes accelerated thickening of the endometrium during the luteal phase.arrow_forwardWhich is/are true concerning the general structure of female reproductive organs? a. the oviducts are found lateral to the uterus, along the pelvic brim b. the vagina is located posterior to the bladder and anterior to the rectum c. the distal opening of the oviduct is surrounded by the finger-like fimbriae, which serve to guide a recently ovulated ovum into the oviduct d. the cortex of the ovary contains the helicine arteryarrow_forward

The production of primary oocytes continues in women from the onset of puberty until the onset of menopause. b. Meiotic divisions are complete at the time of ovulation. c. At ovulation, the structure released from the follicle includes a secondary oocyte and polar body. d. All of these statements are correctarrow_forwardWhich of the following statements does NOT describe the events that occur if the ovum is not fertilized? Select one: a. The corpus luteum degenerates and stops producing estrogen and progesterone. b. GnRH, FSH, and LH levels begin to increase. c. Progesterone maintains the endometrium for the zygote. d. Low levels of progesterone result in menstruation.arrow_forward
- A. There is an increase of FSH at the beginning of the menstrual cycle. What causes it? B. There is a surge in E2 level before the ovulation. What causes it? C.

There is a decrease of LH and FSH after ovulation. What causes it? F. There is a decrease in E2 after ovulation. What causes it? G. There is an increase of E2 and P4 a few days after the ovulation. What causes it? H. There is a decrease of E3 and P4 at the end of menstrual cycle. What causes it?arrow_forwardWhich of the following embryological events is involved in the formation of the ovarian follicles? a. Development of a genital tubercle in the cranial and the cloacal membrane b. Differentiation of the endoderm of the urogenital sinus c. Formation of longitudinal invaginations along the lateral aspect of the mesonephros d. Innervation of the ovary by neural crest cells e. Migration of the primordial germ cells from the yolk sacarrow_forwardWhich of the following rows identifies the site of fertilization, and the hormone released when the fertilized egg implants, respectively? Select one: a. Site of Fertilization Hormone Released Fallopian tube hCG b. Site of Fertilization Hormone released Uterus hCG c. Site of Fertilization Hormone released Uterus Aldosterone d. Site of Fertilization Hormone Released Fallopian tube Aldosteronearrow_forward
