Document Summary

Psychology 2075: chapter 6 - conception, pregnancy, and childbirth. The egg is released from the ovary into the body cavity, picked up by the fimbriae, and enters the fallopian tube. It then begins a leisurely trip down the tube toward the uterus, reaching it in about five days if it has been fertilized. The sperm is one of the tiniest cells in the human body. It is composed of a head, a midpiece, and a tail. Conception occurs in the outer third of the fallopian tube. Hyaluronidase: an enzyme secreted by the sperm that allows one sperm to penetrate the egg. Zygote: the developing organism from the time of the union of the sperm and the egg to about the second week of gestation. Between weeks two and eight it is called an embryo, and from then until birth it is called a fetus. Improving the chances of conception: making a baby.
