The Sperm and the Egg Essay Rhettman Mullis The Sperm and the Egg Hello, my name is Eve and today is going to be the most exciting day of my life. It has been a really long journey but I have finally made it to the infundibulum, this is the outer part of a women’s fallopian tube. My medical name is known as â€Å"Ova†, but to my friends I am known as Eve or Egg. I have recently been in contact with a germ cell named Adam. His medical name is known as â€Å"Sperm† and he lives inside of a human body of a male. Adam and I have been dreaming and planning this adventure for quite some time now. I am just praying that when we finally do meet that everything goes according to plan. You see, this day is so important because when Adam and I meet we will be joining as one to create a life. When we unite we will create either a male or female embryo which will grow into a baby. This process all starts with the life of a female human being. When a female child is born they are born with all the ova they will ever have throughout their life, which is about 2 million. After about 15-17 years that child is more developed and goes through a stage in their life called puberty. Only about 400, 00 of the 2 million Ova make it through this stage in a women’s life. I was lucky enough to be one of those 400, 00 who made it through. After this stage myself and the remaining ova resided in a thin capsule inside the women’s ovaries called the follicle. When the woman has reached her reproductive years and the ova have reached their full ripened potential they will be released in hopes of fertilization. There are only about 400 ripened ova that typically make it to possible fertilization. This is roughly 1ova per month (Rathus, S. A. , Nevid, J. S. , amp; Fichner-Rathus, L 2011) and today is my day, the day I have been planning my whole life. Today is the day Adam and I will embark on a journey to create a life. I have just been released and am now making my way to the fallopian tube. Once I reach the fallopian tube I will wait for Adam patiently and we will set off on our journey together. Traveling down the fallopian tube is about a 4 inches long, and will not be a quick trip, however it is vital. The fallopian tube works like a passageway to help nourish and conduct myself and other ova passing through on our way to the uterus. Cilia are hair like projections that line the fallopian tube that help me along my journey. The cilia move me through the tube about 1 inch day. Fertilization usually occurs in the infundibulum, within a couple of inches of the ovaries because ova must be fertilized within a day or two after they are released from the ovaries. Rathus, S. A. , Nevid, J. S. , amp; Fichner-Rathus, L. 2011). During which my host will begin the ovulation process, and within two weeks we will have either created a life or my host will menstruate. Adams journey will begin in the seminiferous tubules, which is located inside of male’s testes. While in this location Adam will develop which will take about 2 months for him to reach his full ripened potential. Onc e Adam is developed and ready to go he will travel to the epididymis where he will be carried to the urethra from the force of ejaculation. Once in the urethra Adam will meet a mixture of secretions that were created by his host’s prostate gland. This mixture that was created will help Adam find his way to Eve to begin their journey together. When Adam’s host is sexual aroused and is about the ejaculate his pelvic muscles will begin to contract. Adam will now leave the males body through the releasing of the mixture through the penis and inserted in the vagina. Once Adam and I meet we will begin the fertilization process. This is where we will begin to create the human life we have always dreamed about. Adam’s 23 chromosomes from the father’s sperm cell combine with the 23 chromosomes from the mother’s ovum, furnishing the standard ensemble of 46 in the offspring. Among the 23 chromosomes borne by sperm cells is one sex chromosome—an X sex chromosome or a Y sex chromosome. Ova contain X Sex chromosomes only. The union of an X sex chromosome and a Y sex chromosome Leads to the development of male offspring. Two X sex chromosomes combine to yield female offspring (Rathus, S. A. , Nevid, J. S. , amp; Fichner-Rathus, L. 2011). Adam and I have great news to present, the trip when according to plan and together we have created a baby girl. It was a long journey and at time we were not quite sure if everything was going to work in our favor. Despite it all everything worked out and we have successfully completed this mission and our goals in life. REFERENCES Rathus, S. A. , Nevid, J. S. , amp; Fichner-Rathus, L. (2011).
