Anatomia aparatului genital feminin |
|
Reproducerea este o caracteristica fundamentala a oricarei fiinte si se realizeaza prin participarea a doua organisme de sex diferit. Ea este rezultatul fecundarii gametului feminin (ovul) de catre gametul masculin (spermatozoid). Oul rezultat se grefeaza in cavitatea uterina, unde continua sa creasca si sa se dezvolte pana ce fatul devenit viabil este expulzat din uter prin actul nasterii.
Diferentierea sexuala este prezenta inca din momentul fecundarii oului, dfar diferentierea intersexuala somatopsihica are loc lent in timpul copilariei si se realizeaza dupa pubertate ca urmare a activitatilor gonadelor. In copilarie, hormonii sexuali secretati in cantitati reduse contribuie, impreuna cu ceilalti hormoni, la cresterea si dezvoltarea armonioasa a organismului, iar dupa pubertate, acesti hormoni secretati in cantitati crescute la femei cu anumite caracteristici ciclice, intretin functia sexuala. Organizarea morfofunctionala a sistemului reproducator la ambele sexe este extrem de complexa, gonadele avand atat functia de a produce gameti (ovule si spermatozoizi) cat si pe cea de a secreta hormoni sexuali, care prin diferitele lor activitati asupra organelor genitale si asupra intregului organism, asigura conditii optime pentru reproducere. .

Maturatorii de aur.polenizatorii |
|
Albinele sunt cei mai prolifici polenizatori, dar nu singurii. Viespea-paianjen se hraneste cu polen de aclepia. Gandacii se numara printre cei mai vechi carausi de polen.Polenul unei orhidee-de-smarc e amplasat la gura florii, ca tantarul care ajunge la ea sa poata lua o trompa plina.
Pentru a se reproduce, cele mai multe plante cu flori depind de o terta parte, care sa transfere polenul intre partile lor masculine si feminine.Unele au nevoie de incurajari suplimentare pentru a renunta la pulberea lor de aur.De pilda, floarea de patlagea-rosie are nevoie de o scuturatura violenta, o vibratie cam de 30 de ori cat atractia gravitationala a Pamantului.............................. .

Cleopatra |
|
Cleopatra Vll was born in 69 BC, in Alexandria, Egypt. Despite what people say today, that she was glamorous and beautiful, she was far from it.
She is shown on ancient coins with a long hooked nose and masculine features. Although she was not beautiful she was clearly a very seductive woman, and she used this to further Egypt politically. She had a beautiful musical voice. It is also said that she was highly intelligent. She spoke nine different languages, and she was the first Ptolemy pharaoh who could actually spoke Egyptian. She ascended the Egyptian throne after her father, Ptolemy Xll Auletes died in 51 BC. Cleopatra which was seventeen at the time and her brother Ptolemy Xlll, which was twelve, were married because of the terms of her fathers will. They then ruled Egypt together. In the third year of their reign Ptolemy’s advisers told him that he should rule Egypt by himself. So, because of this he drove Cleopatra into exile. Cleopatra then escaped to Syria. She then returned with an army. Ptolemy sent an army to meet with her. At this point, Julius Caesar of Rome arrived in pursuit of an enemy, who was seeking help from Ptolemy. Cleopatra had to roll herself up in a rug so that she wouldn’t get killed while entering Egypt. If she hadn’t hidden herself she would have been killed. When she unrolled herself in front of Caesar he fell in love with her right away.Caesar had to choose which of the Egyptian rulers to help keep the throne. Of course he chose Cleopatra. He then became Cleopatra’s lover. In 47 BC Ptolemy Xlll drowned in the Nile while trying to escape, and Caesar then restored Cleopatra to her throne. . Cleopatra |
