Early Child Development Essay -- Child Development Psychology Sociolog

Early Child Development There be many a(prenominal) key factors that play up to the role of early child development, starting signal from before the child is nonexistent, until the child is a full grown baby. bodily Processes of Re intersection There are numerous hormones in the human body that play key factors in allowing a human being to cat successfully.Spermatogenesis Spermatogenesis is the 65 to 75 day process in which the human manful anatomy produces spermatozoon cells. In the male person body, follicle-stimulating hormones, or FSH, and leutinizing hormones, or LH, are very important in the process of spermatogenesis. These hormones control sperm re intersection. The production of the hormones testosterone and androgens are stimulated by the leutinizing hormones. During this process, the follicle-stimulating hormones motivate the testes to produce sperm. The development of the sperm takes place in twisted tubules called seminiferous tubules. Mitosis o ccurs, in which the diploid cells reproduce themselves constantly. Then, day by day, at least 3 million of these cells write down to undergo meiosis, where the number of doubled chromosomes is reduced in half by dividing the cell over and over again. In severalize for the first physique of Meiosis to begin, the cell must become a primary spermatocyte. after(prenominal) this has occurred, the diploid cell, which has 46 chromosomes, split into ii haploid secondary spermatocytes, each(prenominal) containing only 23 chromosomes. In the next phase of Meiosis, Meiosis II, the two cells split, again, forming four cells also consisting of 23 chromosomes, and the cell undergoes the change in order to perform its more specialized function for reproduction. This production takes place in the male gonads, also known as the testes. Oogenesis Oogenesis, also called ovigenesis, is the process in which the female anatomy produces egg cells. The egg cell is made up of three layers a jelly coat, the vitelline layer, and the egg cells plasm membrane. A hormone called gonadotropin releasing hormone, or GnRH, control the production of the follicle-stimulating hormones and the leutinizing hormones that, as stated above, are also found in the male body. The process of oogenesis is similar to spermatogenesis. Although produced by the leutinizing hormones, the androgen hormones control the levels of FSH, GnRH, as wholesome as the LH. Oogenesis begins before bi... ..., M.D., F.A.A.P., Robert, (2001) Alcohol and Drugs During Pregnancy.
