Physiology of Fertilisation
Steps
Second step: acrosome reaction
release of chemical enzymes
acrosin
establishing a pathway for sperm cell
Third step: fast block to polyspermy
opening of sodium channels
prevent to polyspermy
First step: preparation of the sperm (capacitation)
removal of glycoproteins and seminal protein
increase motility and metabolism
increase the level of Ca+
Last step: slow block to polyspermy
membrane of ovum and sperm fuse
sperm nucleus passes into ovum
opening of Ca+ channels
Definition
fusion of gametes
Place
ampulla of the fallopian tube
Impoetance
transferring of genetic material
the formation of a unique individual
