Q

Physiological Criteria of Uterine Contractions

  • Polarity
A
  • When UUS contracts & retracts, LUS relaxes & dilates (actually, lower part contracts but much less than upper part).

Q

Physiological Criteria of Uterine Contractions

  • Retraction
A
  • Shortening of muscle in response to stimulus but doesn’t return to its original length when contraction has passed.
  • Retraction occurs in UUS & is responsible for fetal descent & control of postpartum bleeding.
