LM of sperm on egg during fertilisation
Numéro d’image : 12071132
| Fertilisation. Light micrograph of sperm clustered around a human egg (ovum) during fertilisation. The rounded egg is at centre. Sperm can be seen free swimming or attached to the egg surface. They appear as fine hair-like structures,each with a rounded head and a long tail. They are penetrating the thick spongy zona pellucida of the egg,a surface layer that attracts sperm to the egg and enables the sperm to attach. The human female usually produces a single large egg,and only one of the millions of male sperm may penetrate the egg's wall to fuse with the egg nucleus. Once fertilised,the egg begins its process of growth by cell division. Magnification: unknown | |
