Answer 1

1) uterine tube

• Uterine tube also known as fallopian tube , that stretches from the uterus to ovary and are a part of female reproductive system.
• Finger like projections at the end of uterine tube , which recieve oulated egg and fused with male sperm at ampulla for fertilization.
• Option A is wrong because oocyte is released from ovary.
• Option B is wrong because cervix is a cylinder shaped tissue located below uterus .
• Option D is wrong because ductus deferens is a male reproductive structures.

2) corpus spongiosum

• Corpus spongiosum is a mass of spongy tissue that surround male urethra .
• Main function include erection and  prevent the urethra from pinching closed , thereby maintaining the urethra a viable channel for ejaculation.
• Option A is wrong ductus deferens transport sperm from epididymis and ejaculatory duct.
• Option B is wrong epididymis is a long coiled tube that carry sperm from testicle.
• Option C is wrong because urethra is a common passage for urine and sperm.

3)   receive, retain, and nourish a fertilized ovum

• Uterus is a hollow muscular organ ,present in female pelvis between bladder and rectum.
• Implantation of fertilized ovum occur at the endometriumof uterus .
• There are three layers for uterus (from inside to outside ) :- endometrium , myometrium , perimetrium .
• Option A is wrong because uterus doesnot protect ovary.
• Option B is wrong because hormones like progesteron, estrogen regulate menstrual cycle.
• Option C is wrong because ovary produce female hormone.

4) androgen-binding protein

• Sustentocytes are also called sertoli cells.
• Sustenocytes are ells that extend from the basal lamina to the lumen of the seminiferous tubules and surrounds developing cells
• It provid nutrients to developing cell.
• Option B is wrong because sperm is produced by testis
• Option A and D  is wrong because it is released from gonadotropic cells in the anterior pituitary gland

5) Proliferative

• Ovulation occur , at 14th day od 28 day cycle.
• There are mainly 4 phases, menstrual phase , proliferative phase , ovulation and luteal phase .
• Preovulatory phase is also known as follicular phase which include menstrual phase , proliferative phase and post ovulatory phase is also known as secretory phase.
• Duration of menstrual phase is 1-7 days of cycle, hence option B is wrong.
• Option A and D is wrong , which occur after ovulation from 15th day -28th day.

6)    secondary oocyte

• At the time of ovulation , secondary oocyte is released .Which are immature ovum shortly after ovulation , to fertilization , where it turns into ootid.
• Secondary oocyte is produces by meiosis 1 during oogenesis,
• Option A is wrong primary oocyte is produced by during oogenesis of oogonium into primary oocyte.
• Option C is wrong, because oogonium is the undifferentiated cells in females at the birth no more oogonia are present.
• Optiona B is wrong because ovum is produced by ovary, which is also known as ova.
