False-colour SEM of sperm on uterine mucosa
Numéro d’image : 11874106
| A spermatozoon on the uterine mucosa. False-colour scanning electron micrograph of a spermatozoon floating over the endometrium,the internal wall of the uterus. Spermatozoa have pear-shaped heads (bottom right) about 7 microns long and a tail about 60 microns long. This image also shows the two different types of simple columnar cells which populate this area: ciliated (orange-yellow) and secretory (blue). During their journey through the uterus towards the Fallopian tubes spermatozoa undergo a capacitation process which enable them to penetrate and then fertilise an egg.
