Q

Meiosis

A
  • Each oogonium produces a single haploid ovum once some cytoplasm moves into the polar bodies
  • Polar bodies will degenerate
  • Born with oogonia that can develop into eggs
  • FSH causes follicular cells to proliferate -> form the Zona pellucida and Atrum -> use cholesterol to form estrogen (or testosterone in men)
  • Estrogen surge leads to negative feedback which causes LH surge and follicle opens up to release oocyte
  • Each spermatogonium produces four haploid spermatozoa

Q

Cellular Differentiation

A
  • Begins in the blastocyst
  • Inner cell mass becomes embryonic tissues and amnion
  • Trophoblast becomes placenta
  • All tissues develop from the primary germ layers
  • Ectoderm (skin, peripheral nerves)
  • Mesoderm (muscles, CV system, organs)
  • Endoderm (inner lining of organs)
  • Amnion (amniotic sac)
  • Yolk Sac (not important in humans)
  • Allantois (umbilical cord)
  • Chorion (surrounds entire amnion, develops chorionic villi which is the fetal portion of the placenta)

Q

Amniotic Fluid

A
  • Slightly alkaline
  • Lungs are last to develop and need amniotic fluid
  • Functions = cushions against injury, maintains temperature, permits symmetric growth and muscle development, extension of fetal extracellular space, stops fetus from adhering to amnion and prevents cord compression)
  • Oligo = not enough fluid
  • Polygo = too much fluid

Q

Umbilical Cord

A
  • Fuses with the embryonic portion of the placenta
  • Delivers oxygenated blood and nutrients to the fetus
  • Returns deoxygenated blood and waste to the placenta
  • Provides circulatory pathway from chorionic villi to embryo (1 vein, two arteries)

Q

Placenta

A
  • Metabolic and nutrient exchange
  • Maternal portion = from decidua basalis, cotyledons
  • Fetal portion = chorionic villi, covered in amnion (shiny, gray)
  • Placenta and embryo are homografts (exempt from immunologic reaction by host; progesterone and hCG suppress cellular immunity during pregnancy)

Q

Embryonic Stage

A

-day 15 to week 8
-tissues differentiate into essential organs
3 weeks = heart is most advanced
4-5 weeks = somites develop, heart beats and circulates blood, eyes and nose begin to form, arm and leg buds present
6 weeks = head is more developed, jaws and palate start to form, liver is producing blood cells, trunk straightens, digits develop, tail begins receding
7 weeks = head is rounded, GI and GU are separate tracts
8 weeks = embryo is 3cm, resembles a human, facial features continue to develop

Q

Fetal Stage

A

-9 weeks until birth
-every organ and structure is present, structures grow, refine, and perfect function
9-12 weeks = eyelids are closed, tooth buds appear, genitals well differentiated, urine is produced, fetal heart can be heart, spontaneous movement
13-16 weeks = lanugo begin to develop, blood vessels clearly developed, active movements present, makes sucking motions, swallows amniotic fluid, produces meconium
20 weeks = subcutaneous brown fat appears, quickening felt by mother, 8 inches long
24 weeks = eyes structurally complete, vernix caseosa covers skin, alveoli beginning to form, viable outside the womb
25-28 weeks = testes begin to descend, lungs structurally mature (functionally still developing), rapid brain development
29-32 weeks = rhythmic breathing movements, ability to partially control temperature, bones fully developed but soft and flexible
35-36 weeks = increase in subcutaneous fat, skin is plump and less wrinkled, lanugo begins to disappear
38-40 weeks = skin appears polished, maternal antibody transfer (TDAP vaccine!), lanugo disappears except in upper arms and shoulders, fetus is flexed

  • Temperature over 101/chills
  • Dizziness, blurring of vision, double vision or spots (signs of HTN and eventually preeclampsia)
  • Persistent nausea and vomiting
  • Severe headache
  • Edema of hands or face
  • Seizures or convulsions
  • Epigastric pain
  • Dysuria - urinary frequency, -UTI’s (present differently in pregnancy, doesn’t have to have be burning) can cause membranes to get infected and water will break prematurely
