, ____ denotes the spontaneous, rhythmic depolarization of cardiac cells. - Answer Automaticity
As a contraction begins, partial umbilical cord compression causes occlusions of the low-pressure vein
and decrease return of blood to the fetal heart rate, resulting in decreased CO, hypotension, and a
compensatory FHR ____. - Answer Acceleration
the umbilical vein carries what? - Answer Oxygenated blood from the placenta to the fetus.
_______ is the primary neurotransmitter of the parasympathetic branch of the autonomic nervous
system. - Answer Acetylcholine
_____ respond to increases in fetal arterial bp by detecting the amount of stretch and sending impulses
via the vagus nerve to the midbrain, decreasing FHR, CO, and BP - Answer Baroreceptors.
The FHR baseline reflects what physiological process? - Answer Both parasympathetic and sympathetic
response *(intact central nervous system)*
