NM 704 Exam
What are the 3 functions of the bony pelvis? - (1) attachment site and support for pelvic organs
(2) site of attachment and articulation to the lower limbs (3) supports the weight of the upper
trunk and distributes to lower extremities
What nerve innervates the perineum? - Pudenal nerve
What pelvis includes the iliac fossa and the iliac crest, and has little obstetric significance? -
False pelvis
What pelvis includes the pelvic brim from the superior part of the symphysis pubis around the
sacral promontory? - True pelvis
Where does the pudenal nerve originate? - S2, S3, S4
What are hormones that cause an effect on the uterus, such as estrogen and progesterone? -
Uterotropins
What are hormones that cause an effect on the inducing uterine contractions, such as oxytocin
and prostaglandins? - Uterotonins
What are the traditions 4 Ps of labor? - (1) passenger (2) power (3) passage (4) psyche
What is the descent of the fetus into the true pelvis? - Lightening
Who is lightening more common with? - Nulliparous
When does lightening normally occur? - As early as 4 weeks prior to the start of labor
,What is the result of the lengthening of the muscle fibers at the internal os, which stretch the
endocervix upward into the lower uterine segment? - Effacement
In nulliparous women, _______ typically proceeds dilation? - Effacement
The passing of the mucus plug often indicates that labor will start within when? - 48 hours
What is the widening of the external os? - Dilation
What are inhibitors of uterine contractions? - (1) progesterone (2) prostacyclin (3) relaxin (4)
nitric oxide (5) other hormones
When are the inhibitors of uterine contractions present? - Quiescence
What is the main characterization of the activation phase (1) of partuition? - Loss of
progesterone dominance
Where is the uterine muscle the thickest? - At the fundus
What phase of parturition is the stimulation of uterine myometrial activity? - Phase 2
What does the placenta release during phase 1 of partuition that can help transition from
progesterone to estrogen dominance? - CRH
What layer of muscle of the uterus do contractions originate from? - Myometrium
, What happens to the myometrium during the activation phase of parturition? - Becomes more
sensitive to labor hormones
What happens to the myometrium during the activation phase of parturition? - Regular
contractions due to influence of oxytocin and prostaglandings
What hormones predominate during the activation phase of parturition? - (1) oxytocin (2)
prostaglandins
Propagation of contractions wave of fundal dominance? - (1) start in the fundus (2) last longer in
the fundus (3) progress from the fundus toward the isthmus

What type of pelvis has a short anteroposterior diameter and a wide transverse diameter? -
Platypelloid
What are the positional changes the fetus undergoes to accommodate itself to the maternal
pelvis? - Mechanisms of labor
