-Thyroxine (T4)
Ilnnesses:
-T-O-R-C-H
Placenta side ;attached to the uterus
Duncan
Manuever to deliver placenta by applying pressure on lower abdomen
Crede’s Manuever/ Fundal Pressure
Protective structure of umbilical cord from trauma
Wharton’s Jelly
Position of choice Cord Proplapse:
1st: Knee Chest
2nd: Trendelenburgs
-Prevents compression to umbilical cord
-Small passages that direct blood needs to be oxygenated
-To bypass the lungs & liver. be not fully work until afterbirth.

-Growth of the brain
Suture
Normal, when crying
Abnormal, when not crying/ ↑ICP

Early closure of fontanel
early closure is x/sx of abnormality

0Hormone for brain development in fetus
-Iodine forms this hormone
Thyroxine (T4)
GOOD TO KNOW!
-No intermingling of maternal & fetal blood occurs in the placenta.
-Mixing of blood of mother and fetus occurs by 3rd stage of labor
-Spaces between bone of skull
-allow molding during birth

Suture that divides 2 halves of frontal bone
Metopoic
Suture that extends across the skull between parental & frontal bone
Coronal
Suture between two parietal bones
Sagittal
Suture between occipital and two parietal bone at the back of skull
Lamboidal
-Birth defects, skull joined too early before brain fully formed
-Premature closure of cranial suture
-2 y.o., before brain becomes developed
