spermato genesis:
The primary germ cells present in the seminal nuclei of the testicle begin to form the sperm cells in the semen. In many vertebrates, the sperm cells are located in the outer region of the spermatozoa, where the outer membrane of the spermus is attached to the semen. However, what remains of them outside the spermic tubules and inside the connective connective tissue With a built-in catheter.
(1) Multiplication phase:
The semen is divided into a number of times related to the type of object to give a large number of semen mothers to form a source of new sexual cells.
(2) Growth stage:
Some sperm cells continue to divide and some begin to grow. Each one is divided into two cells, each of which enters a growth stage by increasing the size of the cell by increasing the amount of cytoplasm known as primary or primary sperm cells, the largest sperm cells, Semen and be in a continuous split state.
(3) Maturity stage:
The primary sperm divide is divided by the first mitotic fraction after multiplying the chromosome DNA to give each cell two cells, each known as the secondary sperm cell containing half the number of chromosomes found in the sperm cells of the semen, which are smaller than the previous ones and also turn towards the center and have a dark nucleus In turn, it is divided in the case of the composition of the sperm by the second mitotic division to give four small cells with a small, central, dark central nucleus, the seminal vultures that pass through a differentiation phase in which all sperm components are formed. In summary, the mother cell of one semen grows to be a primary sperm cell divided by the first equitable division to be two secondary cells and two are divided in the division of equitable to be the two vowels are differentiated to the spermatozoa and so each cell of semen formed four mature sperm cells half chromosomes accumulate in Anibiba Center in the form of cellular groups.
(4) differentiation stage (shift):
The seminal viability is characterized by the ability to move and fertilize in a process known as the velocity shift. It involves the mutation of the seminal vesicle from an ordinary cell with a small, spherical and small central globular nucleus, chromatin bodies, a clear number of Golgi and mitochondria, two central bodies and a cytoplasm containing cellular organelles.
