{I already really know all I need to know about embryology. | |||
|type="()"} | |||
- true | |||
+ false | |||
|| If you said '''true''', how can that be, as we have not yet begun to explore this topic in detail. You clearly don't understand enough to even answer this first question correctly. | |||
{Which of the following statements is most correct about the human menstrual cycle. | |||
|type="()"} | |||
- The menstrual cycle in all women is a 28 day reproductive cycle | |||
- Ovulation always occurs at the midpoint of the menstrual cycle | |||
- The menstrual cycle's main function is to regularly replace the lining of the uterus | |||
- A high body temperature indicates ovulation is occurring | |||
+ The menstrual cycle is an endocrine cycle regulating reproductive physiological changes | |||
||The menstrual cycle is variable amongst women and also within an individual, the "28 days" is an average time course. Like the cycle itself, the time of ovulation can vary anywhere between day 10 - day 19. The uterine lining (functional layer) is replaced ever cycle, though this would not be considered the main function of the cycle. The body temperature does increase at ovulation, but it remains high even after this point, it is the time of change that indicates ovulation. | |||
{Most pregnancies can be detected by pregnancy tests soon after fertilization. | |||
|type="()"} | |||
- true | |||
+ false | |||
|| Following fertilization, at least 1 to 2 weeks of development must occur before implantation commences, it is only after implantation that regnancy tests work. | |||
{Which of the following statements is correct about the zona pellucida: | |||
|type="()"} | |||
- surrounds the oocyte in the ovary | |||
- protects oocyte in the uterine tube | |||
- is a specialized extracellular matrix | |||
- is important for fertilization | |||
+ all of the above | |||
||Yes, the [[Z#zona pellucida|zona pellucida]] has many different functions at different times of oocyte development, fertilization and in the first week of development. | |||
{Pregnancy tests generally are based upon the detection in maternal urine of: | |||
|type="()"} | |||
- Estrogen | |||
- Progesterone | |||
- human Chorionic Somatommotropin | |||
+ human Chorionic Gonadotrophin | |||
- human Chorionic Corticotropin | |||
||Estrogen and Progesterone are made in the ovary and support the endometrium. human Chorionic Somatommotropin (or placental lactogen, stimulate maternal mammary development) and human Chorionic Corticotropin are both made by the placenta later in development. | |||
