False-colour SEM of secondary oocyte & polar body Featured 27 Jul 2005 Image

False-colour SEM of secondary oocyte & polar body

Human egg. False-colour scanning electron micrograph of a human egg (primary oocyte) at the end of the first meiotic division, occurring just before ovulation. At this stage the primary oocyte is split into two cells, known as the secondary oocyte (green) and the first polar body (yellow), each containing 23 chromosomes. If after ovulation the secondary oocyte is penetrated by a spermatozoon, it completes the second meiotic division producing a fertilised mature oocyte and one polar body. The first polar body divides into two and all three polar bodies shortly degenerate. Magnification: x700 at 6x7cm size. x1115 at 4x5ins

Collecting duct from a kidney, SEM Featured 27 Jul 2005 Image

Collecting duct from a kidney, SEM

Collecting duct from a kidney. Coloured scanning electron micrograph (SEM) of a section through a collecting duct from a kidney. This section across the duct (a thin tube) shows a thick, folded wall surrounding a narrow central space (lumen). This collecting duct receives urine from the Loop of Henle (which is part of a kidney structure called a tubule). The urine is the product of the blood filtration that occurred elsewhere in the kidney. The Loop of Henle reabsorbs water and salts from the urine, increasing the concentration of waste products such as urea. Magnification: x12, 500 when printed 10cm wide
