On The Dark Side by John Cafferty & the Beaver Brown Band. This was written for Eddie and the Cruisers, a 1983 movie about a New Jersey bar band. In the film, the song becomes the band's big hit and leads to a second album and a conflict with their record company. Kenny Vance was the music supervisor on Eddie and the Cruisers.
The gestational age of 20â29 days was chosen because the fetal size with a crownârump length of 4â6 cm correlates well with the size of a human embryo at about 10â12 weeks, when selective reduction is often performed2.
1 Measure between 11 weeks and 14 weeks. 2  The minimum fetal crownârump length should be 45mm and the maximum 84mm. 3  The success rate for taking a measurement at this gestation is 98â100%, falling to 90% at 14 weeks; from 14 weeks onwards, the fetal position (vertical) makes it more difficult to obtain measurements. Fetus should be examined in a mid-sagittal plane. 2  Fetal neck should be in a neutral position. 3  Fetal image should occupy at least 75% of the viewable screen. 4  Fetal movement should be awaited to distinguish between amnion and overlying fetal skin, because, at this gestation, both structures appear as thin membranes.
