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 3 Most pregnancies can be detected by pregnancy tests soon after fertilization. true false 4 Which of the following statements is correct about the zona pellucida: 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 5 Pregnancy tests generally are based upon the detection in maternal urine of: Estrogen Progesterone human Chorionic Somatommotropin human Chorionic Gonadotrophin human Chorionic Corticotropin 6 The most correct sequence of early development following fertilization is: zygote, blastomeres, morula, blastocyst oocyte, zygote, morula, blastocyst zygote, conceptus, blastocyst polar bodies, zygote, conceptus, blastocyst 7 Which process in the third week of development converts the embryonic disc into the trilaminar embryo. placentation gastrulation neuralation somitogenesis embryonic disc folding 8 The second and third trimesters cover the fetal period of development. true false 9 Which of these statements about environmentally derived abnormal development is incorrect: bacterial and viral infections can sometimes not affect development a specific environmental insult will result in a specific abnormal development outcome the first trimester is the most sensitive period to environmental insults some prescription drugs can lead to abnormal development outcomes rubella virus infection during pregnancy has serious abnormal development outcomes 10 Which of the following statements about Figure 1 (shown below) is most correct: figure 1 shows a normal female karyotype figure 1 shows all human chromosomes figure 1 shows a metaphase spread of a human genome figure 1 shows an abnormality of mitosis

{The menstrual cycle is |type="()"} - norochord to neural plate to neural tube - neural tube to neural plate to neural groove + neural plate to neural groove to neural tube - neural plate to neural crest to neural zone ||The sequence neural plate to neural groove to neural tube represents the gradual folding of a flat surface sheet of ectodermal cells into a closed tube isolated from the embryo surface. The notochord is part of the mesoderm and regulates the initial overlying differentiation process. The neural crest are a population at the edge of the neural plate that do not get incorporated into the neural tube. I think I made up neural zone.

{The neural plate is narrower at the caudal (tail) end and therefore closes earlier than the broad cranial (head) end. |type="()"} - true + false || The caudal or posterior neuropore closes after the cranial or anterior neuropore.

{The correct sequence from cranial to caudal of the secondary brain vesicles is: |type="()"} - prosencephalon, mesencephalon, metencephalon, myelencephalon, rhombencephalon - telencephalon, diencephalon, metencephalon, mesencephalon, myelencephalon + telencephalon, diencephalon, mesencephalon, metencephalon, myelencephalon - prosencephalon, diencephalon, mesencephalon, myelencephalon, metencephalon ||The prosencephalon and rhombencephalon are primary brain vesicles. The others are distractors using your lack of understanding of what the terms mean.
