Growth and Development Flashcards
Briefly describe the process of development from fertilization to implantation.
Following fertilization, the zygote undergoes cleavage, forming a morula, which then develops into a blastocyst. The blastocyst implants into the uterine wall, initiating pregnancy.
Describe the main causes and treatments of infertility.
Infertility can result from various factors such as hormonal imbalances, reproductive system abnormalities, or lifestyle factors. Treatments include medication, assisted reproductive technologies (ART), or surgical interventions.
What are the main anatomical changes that occur from birth to adolescence?
The main anatomical changes that occur from birth to adolescence include growth in height, development of secondary sexual characteristics, increased muscle mass, and changes in bone structure.
Describe the significance of organogenesis for normal embryonic development.
Organogenesis is significant for normal embryonic development because it is the process of organ formation from the three germ layers (endoderm, mesoderm, and ectoderm), leading to the development of essential organs and structures.
What are congenital malformations, and what are their main causes?
Congenital malformations are structural or functional anomalies present at birth. They can be caused by genetic factors, environmental factors (such as exposure to teratogens during pregnancy), or a combination of both.
Explain the significance of assessing prenatal development using ultrasound, amniocentesis, and CVS.
Prenatal development is assessed using ultrasound to visualize the fetus, amniocentesis to analyze amniotic fluid for genetic abnormalities, and chorionic villus sampling (CVS) to obtain fetal cells for genetic testing.
True or False: Organogenesis is the process of organ formation during embryonic development.
True: Organogenesis is indeed the process of organ formation during embryonic development.
True or False: Infertility refers only to the inability to conceive naturally.
False: Infertility can refer to the inability to conceive naturally or carry a pregnancy to full term.
True or False: Congenital malformations are always caused by genetic factors.
False: Congenital malformations can be caused by genetic factors, environmental factors, or a combination of both.
True or False: Ultrasound is a common method used to assess prenatal development because it is non-invasive.
True: Ultrasound is non-invasive and commonly used to assess prenatal development.
True or False: Postnatal growth and development are influenced by genetics, hormones, and nutrition.
True: Postnatal growth and development are influenced by genetics, hormones, and nutrition.
