| Descriptio |
English: 9-Week Human Embryo from Ectopic Pregnancy (7th week p.o.)
The size and anatomic features suggest development equivalent to a nine-week pregnancy (or seven weeks post ovulation).
In obstetrics, pregnancy is dated from the first day of the last menstrual period, which is about two weeks prior to the ovulation that resulted in the pregnancy. For the photo, I immersed the formalin-fixed specimen in absolute alcohol (which, because of its low specific gravity, allows the specimen to firmly sink to the bottom of the dish and not float around). I shot the picture with an expensive Nikon D2X, but I used an old, worn, cheap Nikkor f/4 manual-focus 105mm macro lens, courtesy of the eBay shopping experience. In this case, I added a Nikkor 1.4X tele-converter, which gave me just the right image size and working distance. The picture would have been fine without the tele-converter, requiring just a little mote cropping. Español: Embrión humano de 9 semanas del embarazo ectópico El tamaño y las características anatómicas sugieren un desarrollo equivalente a un embarazo de nueve semanas (o siete semanas después de la ovulación). En obstetricia, el embarazo está fechado desde el primer día del último período menstrual, que es aproximadamente dos semanas antes de la ovulación que resultó en el embarazo. Para la foto, se sumergió la muestra fijada con formalina en alcohol absoluto (que, debido a su baja gravedad específica, permite que la muestra se hunda firmemente en el fondo del plato y no flote). Se grabó la imagen con una costosa Nikon D2X, pero utilizando una lente macro de 105mm de foco manual Nikkor f/4, vieja y gastada y barata, cortesía de eBay por la compra. En esta situación, se agregó un teleconvertidor Nikkor 1.4X, que proporcionó el tamaño de imagen y la distancia de trabajo correctos. La imagen resultante quedó bien, requiriendo sólo un pequeño recorte. |
