Document Summary

**after cells pass through primitive node, they spread laterally and cranially. Capacitation: activations of sperm cell, allows fertilization to occur, increase motility, change head shape, this happens when it makes contact with corona radiate. Tubal pregnancy, usually terminated because if tubes burst it can cause death of mother and fetus. **know all times: 12-24 hours after ovulation.
