The Adventure of the Sperm and Egg Essay Example for Free

The Adventure of the Sperm and Egg Essay Let me introduce myself, I am Penny the Egg and today I will embark on one of the most exciting times in my life span. This has been a long expedition and now that I have reached the infundibulum, this is the outer portion of a female fallopian tube. The name I was in the medical word is â€Å"Ova†, most people just call me egg but my name again is Penny. I have been in contact with a germ cell named Seymour. His medical name is sperm and he lives inside the male human body. Seymour and I have been dreaming about this adventure for our whole lives. I am hope everything goes as planned and Seymour and I get to meet. After we meet, we will become one to create another male or female embryo which will grow into a human baby. As the â€Å"Great Change† occurs, medically that would be puberty for a female; I was one of 2 million ova that once lived inside the female. After the great change there are around 400,000 of my sisters and I left. We all live inside the follicle; these are thin capsules inside the ovaries. Out of the 400,000 of us that survived the great change, only 400 or so of us will reach fulfillment and become a ripened ova (Nevid, Rathus Fichner-Rathus, 2011). When I have ripened to fulfillment I will leave the safety of the ovary where I spent my childhood, I have made my way to where I am now, the fallopian tube. This is where I will wait for Seymour to arrive. It takes me some time to travel down the fallopian tube, and during this time is when my female host will ovulate, and then two weeks later my host will menstruate unless Seymour and I create life. The length of my travel is around 4 inches, but I must travel different parts of the tube in order to be totally ready to meet Seymour. As I travel the fallopian tube, I will come a crossed various small groups who call themselves Cilia. The Cilia groups have miniature hair-like projections that help me along my travels’. I could not make it an inch a day without the help of the Cilia. I dream about Seymour and our meeting day and worry that my female host will not allow me to be discharged with her menstruation. I have now been in the fallopian tube for just over a day now and I pray that Seymour is skillful enough to make it in enough time to help me create life. If Seymour does not arrive within two day of my leaving the ovary, I will not be here to meet him and no life will be created (Nevid, Rathus Fichner-Rathus, 2011). I am the type of egg to worry all the time, I wonder if Seymour’s trip is going according to plan? I just hope Seymour is strong and fast enough to out swim his brother’s taking this adventure also. Hello everyone my name is Seymour the sperm, I ‘m sure by now you know Penny and I am sure she told you I have millions of brothers’. Honestly, I cannot wait to take that adventure because it is too crowded and very uncomfortable for me in here. I just hope I am strong enough and can survive the adventure, why worry? You ask, because many of us do not survive and it can be a very fatal because it is a false adventure, but I know that to keep life going I must swim as fast and hard as I can to meet my Penny. My Life began in a place in the male host body called the testicles. This is where I went through a 72 days process of spermatogenesis. In order for me to meet Penny inside her female host, I had to endure this process. I have been told that Penny only holds the X chromosome (female), and I contain a Y chromosome (male) and the X chromosome. Once Penny and I meet our sex chromosome will connect and I have one of the most important jobs at this point I will decide if Penny and I will create the life of a male or female, because I alone can make I male with the Y chromosome (Nevid, Rathus Fichner-Rathus, 2011). After my preparation for my adventure, I make my way to the epididymis while in this transition, I continue to mature. It will take a few more weeks for me to be able to move to the Vans Deferens tube of my male host. I will continue my adventure to meet my Penny by making my way into the seminal vesicle; this is where I get all my nourishment from seminal fluid rich in fructose. The nutrition I receive from the fructose in the seminal fluids is what will make me strong enough to out swim my brothers’ to meet Penny. I have discovered I look a lot like a tadpole. I have a tail that whips back and forth to move me forward. Before I matured to this â€Å"tadpole† stage my movements were conducted by the contractions in the epididymis, Vans, Deferens, and just like Penny, I also had help from groups of cilia (Nevid, Rathus Fichner-Rathus, 2011). As the prostate and Cowper’s are making secretions, I continue my adventure. The secretions the other organs are making are what my brothers’ and I will mix with in the ejaculation proses. Yes, I made it to the point I am ready to be ejected from the male’s penis darning sexual intercourse. Once this happens I can begin a whole other adventure to meet Penny in the fallopian tube of her female host. My male host has ejected me and my brothers from his body to Penny’s female host. I must move faster than I have ever moved before. Millions of my brother s are trying to get to my Penny also and will race through the cervical canal, onto the uterus, we will continue to battle to be the first one to successfully reach an ovum (Penny) waiting just outside the opening to the fallopian tube. I did it! I was the first one to reach the ovum and penetrate Penny’s hard outer lining. Even thou many of my brothers’ might find her, once I am inside the lining Penny will go through a chemical change that will insure we become an embryo. We will travel together down the rest of the fallopian tube so we can implant ourselves into the uterus until birth as a human .
