Figure 43.17 Which of the following statements about the menstrual cycle is false? Progesterone levels rise during the luteal phase of the ovarian cycle and the secretory phase of the uterine cycle. Menstruation occurs just after LH and FSH levels peak. Menstruation occurs after progesterone levels drop. Estrogen levels rise before ovulation, while progesterone levels rise after.
Figure 43.8 Which of the following statements about the male reproductive system is false? The vas deferens carries sperm from the testes to the penis. Sperm mature in seminiferous tubules in the testes. Both the prostate and the bulbourethral glands produce components of the semen. The prostate gland is located in the testes.
2 3 K. Seme 456 carries sperm from epididymis to ejaculatory duct copulatory organ; passageway for urine and sperm organ that produces sperm secretes 60% of semen volume; alkaline pH; prostaglandins secretes 25% of semen volume; increases viability and motility of sperm secretes mucus for lubrication of glans; alkaline pH site of storage and maturation of sperm FIGURE 38.8 Function of the male reproductive organs, sagittal section. 7

V. Sequence of Events: Spermatogenesis Thousands of sperm are produced each second. Insert numbers in the spaces provided to arrange the events of spermatogenesis in the proper order. A Daughter cells of spermatogonia differentiate into slightly larger cells called primary spermatocytes, which move toward the lumen of the seminiferous tubule. _B Spermatids differentiate to form heads and tails and eventually transform into mature spermatozoa (sperm), each with 23 chromosomes _C Each secondary spermatocyte divides to form two spermatids. D Spermatogonia in the walls of the seminiferous tubules divide by mitosis to produce two daughter cells, each with 46 chromosomes. E. Through meiosis, the primary spermatocyte yields two genetically unique secondary spermatocytes, each with 23 chromosomes.

1) Trace the path of a sperm cell from the site of its maturation to the site where it leaves the male body. Include descriptions of fluids added along that path. 2) Chronicle the events of the female sexual cycle including hormonal control with particular emphasis on the overlap and regulation of the ovarian and menstrual cycles. What are differences if fertilization does not take place vs. when a pregnancy intervenes?

Some Functions of the Female Reproductive System 1. transports the ovum from the ovary to the Fallopian tubes 2. supplied richly with blood vessels to support the fertilized egg 3. the entrance for sperm as well as the birth canal for the fetus 4. site of fertilization 5. opening to the uterus Match the functions of the female reproductive system numbered above with their structure below. Number: Structure: Vagina Endometrium Fallopian tubes Cervix
PART II. TRUE OR FALSE 1. The glans penis and the clitoris are always covered by a prepuce. 2. The ovaries and the uterus are the primary female sex organs. 3. Ejaculation is the discharge of semen from the erect penis. 4. The labia minora of the female genitalia are homologous to the body of the penis. 5. Meiosis is unique to the gonads. 6. Sympathetic stimulation of the arteries within the penis causes engorgement of the erectile tissue as arterial flow increases and venous drainage decreases. 7. Mammary glands are modified sudoriferous glands. 8. Prolactin causes the breasts to enlarge and the mammary glands to mature during puberty. 9. Secretions from the vestibular glands moisten and lubricate the vaginal orifice during sexual arousal. 10. The secretory phase of menstruation is from the time of ovulation until the start of the menstrual phase.
