early deceleration in fetal heart rate monitoring, a transient decrease in heart rate that coincides with the onset of a uterine contraction. late deceleration in fetal heart rate monitoring, a transient decrease in heart rate occurring at or after the peak of a uterine contraction, which may indicate fetal hypoxia.
DIFFERENCES:   Internal regulators only respond only to the inside, while external  regulators respond only to the outside.   SIMILARITIES:   Both internal and exâ¦ternal regulators can stop their processes.
Positive and Negative Feedback. 1  They are ultra-stable, meaning the system is capable of testing which way its variables should be adjusted. 2  Their whole organization (internal, structural, and functional) contributes to the maintenance of balance. 3  Physiology is largely a study of processes related to homeostasis.
