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.
These structures transmit sound vibrations to the inner ear. In so doing, they act as a transformer, converting sound vibrations in the external ear canal into fluid waves in the inner ear. The inner ear chamber contains tiny hearing and balance nerve endings bathed in fluid. The inner ear is a delicate, tissue-lined sense organ, which is encased in an outer hard bony shell.
