QUESTIONS AND CORRECT DETAILED ANSWERS (100% VERIFIED
ANSWERS) |ALREADY GRADED A+| ||PROFESSOR VERIFIED||
What physiologic input increases in the second trimester,
innvervated via vagus nerve, and eventually becomes dominant
over sympathetic stimulation so that baseline FHR slows? -
ANSWER-Parasympathetic
What is found in the aortic arch and CNS, sensitive to changes in
O2 and CO2 content in blood? When the CO2 increases it
increases the vagus nerve and slows the FHR in neonate. -
ANSWER-Chemoreceptors
What is found in aortic arch and carotic arch, rapidly detects
changes in BP rises and quick reflux occurs to slow the heart
rate? - ANSWER-Baroreceptors
What is the primary part of the levator ani that is divided into 3
parts: pubovagainalis, puborectalis, and pubococcygeus proper? -
ANSWER-Puboccygeus
,2|Page
What is known as the spincter vaginae, contractions of these
muscles releases the size of the vaginal orifice. Contraction of the
anterior muscle fibers contributes to clitoral erection? - ANSWER-
Bulbocavernosus
What are the major components of the pelvic floor? - ANSWER-
(1) endopelvic fascia (2) pelvic diaphragm (3) the urogenital
diaphragm (4) superficial perineal muscles
What is the diamond-shaped hammock that supports the viscera,
abdominal organs, and pelvic organs? - ANSWER-Pelvic
diaphragm
What is a common point of attachment for a number of layers of
fascia and muscles: bulbocavernosus, superficial transverse
perineal, some fibers of the deep transverse perineal, external
anal spinchter, and levator ani-pubococcgeus? - ANSWER-
Central tendinous point of the perineum
What is the plane that separates the true and the false pelvis? -
ANSWER-Linea terminalis
,3|Page
What has occurred, in cephalic presentations, when the biparietal
diameter has passed through the inlet of the pelvis? - ANSWER-
Engagement
What is a relationship determined when the anteroposterior
diameter of the fetal head is in alignment with the transverse
diameter of the pelvic inlet? - ANSWER-Asynclitism (or synclitism)
What is it when the fetal head is tilted so that the fetal head leans
laterally toward the fetal shoulder somewhat? - ANSWER-
Acynclitism
What is it when the sagittal suture is located midway between the
symphysis pubis and the sacral promontory? - ANSWER-
Synclitism
What describes the mechanisms of labor that describe the
movements made by the fetus during labor? - ANSWER-Cardinal
movements of labor
, 4|Page
What are the cardinal movements of labor? - ANSWER-(1)
engagement (2) descent (3) flexion (4) internal rotation (5)
extension (6) restitution (7) external rotation (8) lateral flexion
What cardinal movements of labor all occur simultaneously? -
ANSWER-(1) engagement (2) descent (3) flexion
What is the mechanical advantage of acynclitism? - ANSWER-
Allows a bigger head to pass through the inlet and allows for
engagement
What is the downside to acynclitism? - ANSWER-If it persists and
the head is deep in the pelvis, it may prevent normal internal
rotation
What is the lower exiting parting of the pelvic curve; the fetus and
the placenta must follow this curve to be born? - ANSWER-Curve
of carus
