Question
TRUE or FALSE Numbers: 67, 69, 71, 73, 74 66-75 A=TRUE B=FALSE 66, Erectile dysfunction in the male can be due to a lack of guanidine monophosphate-T 67. The SRY factor determines the sex of a female 68. The Uterine cycle prepares one Oocyte per month for fertilization T 69. The Luteal phase of the Menstrual Cycle is dominated by the hormone Progesterone 70. The First Day of Menstruation is Day One of the Menstrual Cycle T 71. The Late Luteal phase is dominated by the hormone Estrogen 72. The Proliferative Phase of the uterine cycle results in a Thickening of Endometrium 73. Two days after the formation of the corpus albicans menstruation begins 74. Sperm deposited in the vagina are moved toward the fallopian tubes by peristaltic contractions of the vagina and Uterus 5. The female sexual response has been, and will always be, a mystery to men.TExplanation / Answer
Ans 67. SRY (sex determining region Y protein) also known as Testis determining factor is a gene encoded from a region on Y-chromosome which are present only in males. This region is responsible for initiation of male sex determination. However, in the statement, it states that it determines the sex of female. So, the statement is FALSE.
Ans 69. Luteal phase is the phase after the egg is released (after ovulation) and culminates into menstruation. In this case, the ruptured follicle closes after releasing the egg and forms corpus luteum which starts producing progesterone and estrogen. However, the amount of progesterone is much higher than estrogen. So, the luteal phase is indeed dominated by progesterone. Hence, the statement is TRUE.
Ans 71. In the late luteal phase, the corpus luteum degenerates and stop producing progesterone and estrogen. So, we can not say that the phase is dominated by hormone Estrogen. Hence, the statement is FALSE.
Ans 73. Corpus albicans is the regressed form of Corpus luteum which develops if fertilisation does not take place. This happens on 12th day after ovulation resulting in drop in levels of progesterone and estrogen. Also, around 14th day after ovulation, menstruation starts. So, 2 days after formation of corpus albicans menstruation indeed begins. So, the statement is TRUE.
Ans 74. Peristaltic contractions help the sperm to move towards fallopian tube by decreasing the distance it has to travel. So, the statement is TRUE.
