4) In humans, the egg is released from the ovary and enters the oviduct. How is this accomplished?
A) The egg moves through a small tube that connects the ovary and the oviduct.
B) Peristalsis of ovarian muscles moves the egg into the oviduct.
C) The egg is drawn into the oviduct by the action of beating cilia located in the opening of the oviduct.
D) The force of the follicular ejection propels the egg into the oviduct.
E) The egg propels itself into the oviduct by the beating action of its flagellum.
5) What is the narrow opening of the human uterus called?
A) fallopian tube
B) vas deferens
C) vagina
D) oviduct
E) cervix
6) In vertebrate animals, spermatogenesis and oogenesis differ, in that
A) oogenesis produces one functional ovum, whereas spermatogenesis produces four functional spermatozoa.
B) spermatogenesis begins before birth.
C) spermatogenesis is not complete until fertilization occurs.
D) oogenesis produces four haploid cells, whereas spermatogenesis produces only one functional spermatozoon.
E) oogenesis begins at the onset of sexual maturity.
7) Fertilization of human eggs usually takes place in the
A) ovary.
B) labia minora.
C) oviduct.
D) uterus.
E) vagina.
8) During human gestation, organogenesis occurs during the first trimester. What is the significance of this fact?
A) It allows for early detection of genetic disorders.
B) This may block progesterone production and thus cause a spontaneous abortion.
