Document Summary
Fallopian tubes: two 4- inches extending from the sides of the uterus, in which the egg and sperm travel, fimbriae: outer funnel shaped part of tube with fringe, cilia and hair- like cells that move egg. Together with contractions of tube egg moves 1 inch/ 24 hours: fertilization occurs when egg is still close to ovary. Oogenesis is the development of a mature ovum from initial oogonia uterine lining for pregnancy. October 16, 2017: both oogenesis and spermatogenesis involve meiosis, meiosis is the process of cell division by which reproductive cells, ova and sperm are formed, two divisions and four resulting cells have half the chromosome number. Menstruation: ovulation timing and cycle length based on nutritional or psychological stress, exercise and body fat, even sunshine, regardless of the length of the cycle, variation most likely occurs between menstruation and ovulation.
