Question | Answer |
Gel-like membrane surrounding the ovum | Zona Pellucida |
A fertilized egg is called a | Zygote |
Ranges from conception until birth and lasts about 266 days | Gestation |
The duration of pregnancy is divided into three month periods called | Trimesters |
this trimester lasts from conception through the first 12 weeks | First Trimester |
During this period of time, the developing embryo is most susceptible to toxins, stress, drugs, and nutritional deficiencies | First Trimester |
This trimester ranges from week 13 through week 24 | Second Trimester |
Most of the organs are developed during this phase | Second Trimester |
This trimester lasts from week 25 until birth | Third Trimester |
the period of growth before birth is called | Prenatal |
Begins at fertilization and lasts for 16 days | Preembryonic Stage |
Begins after the sixteenth day and lasts until the eighth week | Embryonic Stage |
Brings the eighth week and lasts until birth | Fetal Stage |
Mitotic division of the zygote is called | Cleavage |
**important To REMEMBER** The PROCESS when a cell splits into Two IDENTICAL daughter cells is called | Mitosis |
**Important to REMEMBER** The growth of organs and tissues in a developing child, the repair of damaged tissue following injury, and the replacement of cells that die through the course of everyday living IS CALLED | Mitosis |
Divides by mitosis to form two daughter cells Called | Blastomeres |
A blackberry-like cluster 16 cells called | Morula |
Hollow space filled with fluid | Blastocoele |
outer most layer of the developing blastocyst | Trophoblast |
About Six days after ovulation, the Blastocyst attaches to the endometrium | Implantation |
the closed sac between the embryo and amnion, containing amniotic fluid is called the | Amniotic Cavity |
the floor of the amniotic cavity is formed by the | Embryonic Disc |
the membranous sac attached to an embryo, providing early nourishment | Yolk Sac |
Produces all organs and tissues of the body in the embryo | Germ Layers |
is one of the primary germ layers, known as the outer most layer | Ectoderm |
is one of the primary germ layers, known as the middle layer | Mesoderm |
is one of the primary germ layers, known as the inner most layer | Endoderm |
A hormone that prompts the corpus luteum to secrete estrogen and progesterone | Human Chorionic Gonadotropin (HCG) |
Develops into the epidermis, nervous system, pituitary gland, optic lens, and salivary glands. | Ectoderm |
develops into bones, muscle, cartilage, blood, and kidneys | Mesoderm |
develops into the epithelial lining of the digestive and respiratory tracts, parts of the bladder and urethra, thyroid and parathyroid glands, liver, and thymus | Endoderm |
The embryonic stage begins and the product of conception is now called an | Embryo |
A transparent sac that completely envelopes the embryo | Amnion |
is filled with amniotic fluid | Amnion |
the Fluid that protects the embryo from trauma as well as changes in temperature | Amniotic fluid |
the outer most membrane of the embryo | Chorion |
Finger like projections that penetrate the uterus | Chorion |
serves as the foundation for the developing umbilical cord | Allantois |
about 11 days after conception, the embryo develops a disk-shaped, pancake like organ called the | Placenta |
Secrets hormones necessary to maintain the pregnancy and supplying the fetus with oxygen and nutrition | Placenta |
the chronic villi projects into maternal blood sinus called | Lacunae |
Connects fetus to placenta | Umbilical cord |
the fetal heart pumps blood to the placenta via to | Umbilical arteries |
the blood returns to the fetus by the way of the | Umbilical vein |
Shunts blood around the liver | Ductus Venous |
and opening to the two atria, shunts blood directly from the right atrium to the left | Foramen Ovale |
livers blood from the right ventricle to the pulmonary artery, bypassing the lungs | Ductus Arteriosus |
Pump oxygen-poor, waste-filled blood away from the fetus and towards the fetus | Umbilical Ateries |
Carries oxygenated blood away from the and placenta towards the fetus | Umbilical Vein |
A fine hair that covers the babys body | Lanugo |
The lanugo is covered by white cheese-like substances called | Vernix Caseosa |
Fetal movement is called | Quickening |
A lipid protein mixture that reduces alveolar surface tension | Surfactant |
Sampling of amniotic fluid | Amniocentesis |
A mother that is having her first baby is called | Primipara |
A mother having her second baby is called | Multipara |
The sequence of events occur during birth is called | Labor |
An unborn child, or another word for baby is | Neonate |
Neonates weighing less then 5.5lbs are considered | Premature |
the process of giving birth is called | Parturition |
These are sometimes known as false labor | Braxton-Hicks Contractions |
the progressive thinning of the cervical walls | Effacement |
the progressive widening of the cervix to the allow for passage of the fetus | Dilation |
the fetal membranes usually rupture during dilation, releasing amniotic fluid, this is often referred to as | Water Breaking |
when giving birth the first appearance of the top of the head is called | Crowning |
A surgical incision that is made between the vagina and the anus to enlarge the vaginal opening | Episiotomy |
when the baby is delivered butt first this is called a ______ birth | Breech |
delivery after the baby that includes the placenta, amnion, and other feral membranes | After Birth |
Following Childbirth, the mammary glands produce and secrete milk to nourish the neonate, this is called | Lactation |
High levels of _______ during pregnancy stimulate the growth of ducts throughout the mammary glands | Estrogen |
High levels of ________ stimulate the development of acini at the ends of the ducts | Progeterone |
A rich in protein and immunoglobulins that provide the neonate with passive immunity | Colostrum |
The anterior pituitary secretes _______, which initiates the production of milk | Prolactin |
The posterior pituitary secretes _______, that causes the lobules in the breast to contract , forcing milk into the ducts | Oxytocin |
pressure changes in the heart causes the foremen ovale to shut, while pressure changes in the pulmonary artery and aorta lead the collapse of the ductus arteriosus | Cardiovascular |
While most neonates begin breathing spontaneously, the first few breaths require considerable effort as they work to inflate the collapsed alveoli | Respiratory |
Neonate have weak ___________ at birth, placing them at risk for infection | Immune System |
Neonates risk becoming hypothermic because their surface area, in relationship to their size, is larger then in an adult is called | Thermoregulation |
Neonates require a fairly high fluid intake because their immature kidneys do not concentrate urine adequately is called | Fluid Balance |
The process of degeneration is called | Senescence |
