Flashcards in Ch 3 Deck (49):
1

ovulating

1 every 28 days corpus luteum (where ovum bursts) secretes hormones to makes uterus ready

2

conception

fertilized in falopian tubes, ovum lives for 24 hrs, sperm 6 days waiting 3-500 make it up of 300 million produced a day

3

egg fertilization

70% mortality rate

4

implantation

btwn 7-9th days, blastocyst burrows into uterine lining

5

amnion

forms from trophoblast, contains fluid that fusions and keeps temp right, 30% die by now

6

blastocyst

4th day forms hollow fluid filled ball

7

embroynic disk

inner layer of blastocyst, becomes organism

8

zygote

first 2 weeks, fertilization, impletation, start of placenta, palcenta and umbilical cord has developed

9

embryo

wks 2-8, groundwork for all structures and organs. ectoderm becomes neural tube, heart begins to pump, four chambers. limbs begin. liver and spleen makes blood, respond to touch, head and features form, neuro system vulnerable to toxins

10

chorion

surrounds amnion, villi and blood vessels emerge from it

11

ectoderm

nervous system and skin, embryonic period

12

mesoderm

muscles, skeleton, ciriculatorysystem, organs, embryonic period

13

endoderm

digestive system, lungs, kidney, glands, urinary tract

14

fetus period

9wk to birth, growth and finishing phase, lungs last

15

Fetus third month

kicks, lungs expand and contract, body becomes connected and organized

16

second trimester

organs are well developed by 20 weeks, most brain neurons in place

17

third trimester

22-26 weeks = viability, fetus gets personality

18

vernix

cheese like skin protection

19

languo

downy hair appears over body keeps vernix stuck

20

teratogens

refers to environmental agent that causes damage during prenatal period, depending on dose, heredity, age, neg influences(nutrition, medical care)

21

teratogen ex

drugs, EtOH, tobacco, radiation, pollution, infectious disease

22

fetal alcohol spectrum disorder

range of physical, mental, behavioral outcomes caused by prenatal EtOH exposure

23

fetal alcohol syndrome

slow physical growth, short eyelids; thin upper lip; smooth philtrum, brain injury or small head due to heavy drinking and 3 cognitive area impairments

24

partial fetal alcohol syndrome

2/3 facial abnormalities and 3 cognitive impairments

25

alcohol related neurodevelopment disorder

normal physical growth, 3 areas of cognitive growth

26

pre-natal nutrition

anencephaly , spine bifida

27

Rh factor

if mom neg and dad pos baby can be pos and if baby becomes pos moms immune system can enter baby and destroy organs and tissues

28

Stages of Childbirth

dilation and effacement of the cervix, delivery of the baby, delivery of the placenta

29

stages of labor

dialation and effacement, transition (contractions at high strength and freq, cervix open totally),; pushing(head appears), birth; delivery of placenta

30

Apgar Scale

Appearance, Pulse, Grimace, Activity, Respiration. Measured 0-2

31

analgesics

pain blocker

32

anesthetics

sensation blocker

33

pre-term infants

born before due date, may be in relation

34

small for dateinfants

probably bad nutrition, full term, bad placentas, baby defects

35

isolette

temp controlled bed, gentle rocking, visual or auditory stimulation, touch, filtered air

36

eye blink

shine light, quick eyelid close, permanent

37

rooting

touch cheek, head turns toward side until 3 wks

38

sucking

sucks rhythmically on anything in mouth, voluntary at 4 mts

39

moro

41

tonic neck

turn head while infant on back and extends that arm and flexes other - fencing

42

stepping

when feet but no weight on ground until 2 mts unless skinny

43

babinski

stroke foot toe to heel toes fan and curl as foot twists until 8-12 mts

44

newborn touch

sensitive on mouth and feet, severe pain sometimes can use anesthetic

45

newborn taste/smell

prefer sweet at birth, can use smell to ID mom

46

newborn hearing

wide variety about, prefer complex, can distinguish at only few days, prefer human speech, recognize all human language

47

newborn vision

least developed sense at birth, limited acuity, not good at discriminating colors, track movement is first muscle exercise

48

neonatal behavioral assessment scale

evals NB relfexes, muscle tone, state changes, responsive to physical and social stimuli, used to compare across many nations

49

anoxia

oxygen deprivation at birth
