The sperm cell makes it journey through the body to make it to the egg. This article discus the journey this sperm cell will make to get to the egg to fertilize it. It starts with talking about the cell and how it works. As it says in the article “The sperm starts out as a round, immobile cell. An important structure, the "acrosomal body," that will eventually develop highly erosive enzymes--able to dissolve the membranes around other cells--is made by Sertoli cells at the newly-developed head of the sperm and sealed in a protective coat.” When the sperm fuses with the egg, which also has undergone divisions within the mother's ovary, the full complement of 46 chromosomes will be present.
Big amounts of cellular fluid within the sperm, called …show more content…
Sertoli cells transfer other things to the developing sperm from the blood stream, since at this point in creation the sperm must not be in contact with blood. The hypothalamus will let out.
However, cellular mechanisms allow slight variations in the information contained on certain portions of the chromosomes to be shuffled during the divisions. This feature ensures that each sperm and egg carry the correct information to make a normal human, but each is different as to the exact traits that will be expressed by the new …show more content…
Without this stimulus, Leydig cells decrease production of testosterone until the circulating concentration drops to a level that will trigger the cycle to start all over again--keeping it in perfect balance. Recall how the sperm are being kept from contact with the blood.
They are locked behind very tight junctions between Sertoli cells that make a collective configuration called the "blood-testis barrier." The male's immune system is programmed to recognize specific combinations of protein markers on the outside of his cells as belonging to his own body--but that programming takes place while he is still in his mother's womb. Were it not for this barrier, sperm cells would be recognized as foreign cells by the male's own immune system and destroyed, rendering the male
