Computer art of sperm and egg during fertilisation
Bildnummer 11874393
| Fertilisation. Computer artwork of a human sperm (centre right) penetrating an egg (yellow) during the process of fertilisation. Other sperm are seen at left. Sperm have an oval head and a hair-like tail which beats with a whiplash motion to swim. The human female usually produces a single large egg from the ovary,while the male releases some 300 million much smaller sperm. The sperm travel through the uterus (womb) and up the fallopian tubes to reach the egg. The sperm must penetrate the egg; this penetration is aided by enzymes contained in the sperm's head. Only one sperm can fuse with the egg nucleus. Fertilisation enables male and female genetic material to be shared | |
