The prostatic gland

Cell

The prostate gland is made up of smooth muscle groups, it borders the urinary and that surrounds the urethra. Additionally, it produces semen. This liquid contains nutrients and protein to protect the sperm. This is certainly known as the hair follicle phase. This is when the hair follicle produces even more estrogen, which will tells the mind that the egg is ready to be released. The uterine liner then thickens as the LH and FSH amounts stay low. The production of gametes is due to meiosis. Meiosis is wherever cells divide to produce four daughter cellular material. These include half of the hereditary information. The four child cells created contain half of the genetic details which is also half the number of chromosomes of the father or mother cell to create haploids. The gametes employed during reproduction are the ejaculation and the egg which are haploids. Each of these have half of the chromosomes (23 chromosomes).

When fertilisation takes place they contact form a zygote. To produce these gametes the parent cellular duplicates plus the chromosomes separated into pairs. These pairs then simply divide to create two skin cells which then divided again to form four daughter cells the gametes. This process is called gametogenesis where cellular material use meiosis to form gametes. For men the production of sperm is called spermatogenesis and then for women the production of ova are called oogenesis.

During spermatogenesis semen cells are produced from stem cells. These stem skin cells multiply by mitosis to produce sperm cells which then affix to the Sertoli cells. The sperm skin cells produced include 23 chromosomes. The ejaculate cells will be produced in the seminiferous tubules from the come cells and therefore are surrounded by Sertoli cells. These kinds of Sertoli skin cells give the sperm cells nutrition and goods from the blood vessels. They also assist to transport the sperm to the central funnel as they expand. During oogenesis an egg cell divides to generate two fresh cells. The nucleus might have split to offer each cellular 23 chromosomes.

One of the cells is definitely the secondary ovum and the other is the polar body. The secondary ovum continues to grow until it reaches total maturity and is then ready for fertilisation once released into the fallopian tubes. The zygote is formed during fertilisation when the two gametes (egg and sperm) merge together. The gametes will be haploid cellular material which blend to create a diploid cell (zygote). A diploid cell can be described as cell which usually contains 46 chromosomes. One of a zygote is a great embryo. Once the egg cell is fertilised, it really is implanted in to the uterus. The zygote is a eukaryotic cellular which contains the necessary hereditary information from the DNA in each gamete. The zygote then divides into small cells simply by mitosis. This division really helps to form the embryo.
