Phase 3 of parturition : Labor
BY INDRANEEL ASHOK JADHAV
FIRST STAGE :
 Show
 Uterine contractions
Hypoxia of myometrium
Compression of nerve ganglia
Cervical stretching
Ferguson reflex
Stretching of peritoneum
BY INDRANEEL ASHOK JADHAV
 Formation of distinct Lower and upper
uterine segments :
1. UPPER SEGMENT :
Actively contracting
Becomes thicker as labor advances
Quite firm or hard
2. LOWER SEGMENT :
Relatively passive
Develops into a much thinly walled passage
for the fetus
Much less firm
