Uterus lining during menstruation, SEM Featured 7 Dec 2005 Print

Uterus lining during menstruation, SEM

Uterus during menstruation. Coloured scanning electron micrograph (SEM) of the lining of the uterus being shed during menstruation. The upper layers (red) are being shed and the breakdown of the underlying blood vessels releases red blood cells (red dots). Menstruation occurs for a few days during a woman's menstrual cycle. Prior to menstruation, the uterine lining (endometrium) thickens to prepare it for the reception of a fertilised egg. If a fertilised egg enters the uterus, it implants in the wall and develops into an embryo. If the released egg is not fertilised, the thickened wall is shed

Pulvilli on a flys foot, SEM

Fly's foot. Coloured scanning electron micrograph (SEM) of pulvilli (tubular hairs) on the base of the foot of a fly (order Diptera). Each pulvillus secretes a solution that forms a bond with the surface on which the fly is standing. This allows the fly to walk on vertical surfaces, or even upside down

Collapsed ovarian follicle, SEM Featured 7 Dec 2005 Print

Collapsed ovarian follicle, SEM

Collapsed ovarian follicle. Coloured scanning electron micrograph (SEM) of an ovarian follicle just after ovulation (release of an egg). The central lumen is filled with red blood cells (yellow) from a collapsed blood vessel. Surrounding the lumen are cuboidal follicular cells (blue). The follicle will form into the corpus luteum, or yellow body. The function of the corpus luteum is to secrete the hormone progesterone to ready the uterus for the implantation of a fertilised egg. If the egg is not fertilised it stops secreting and degrades after roughly 12 days
