During the secretory phase of the menstrual cycle ________. the Graafian follicle forms LH reaches its highest levels estrogen reaches its highest levels progesterone levels are at their highest

?

All of the following statements referring to the uterine cycle are true except ________. FSH and LH directly promote development of the uterine endometrium a decrease in the levels of ovarian hormones signals menstruation estrogen is secreted by the developing follicle in the follicular phase of the cycle the corpus luteum is formed from the ruptured follicle after ovulation

FSH and LH directly promote development of the uterine endomentrium

Select the correct statement about the uterine cycle. During the proliferative phase, levels of progesterone rise as the follicle begins to produce more hormone. During the secretory phase, estrogen levels are at their highest. The menstrual phase of the cycle is normally from day 1 to day 8. If fertilization occurs, the corpus luteum is maintained by a hormone secreted by the developing embryo.

If fertilization occurs, the corpus luteum is maintained by a hormone secreted by the developing embryo

Which of these statements about sexually transmitted infections is false? Chlamydia is caused by bacteria that can often be asymptomatic or bring on a wide variety of symptoms. Genital herpes is caused by a virus that may cause intermittent lesions. Syphilis is caused by a virus that may lead to death if untreated. Gonorrhea is caused by a bacterium that can bring on painful discharges in males.

Syphilis is caused by a virus that may lead to death if untreated

THALAMUS

Erection of the penis results from ________. parasympathetic activation of the bulbourethral glands dilation of the veins in the penis a sympathetic reflex a parasympathetic reflex

a parasympathetic refles

The duct system of the male reproductive system includes all but which of the following? urethra corpus spongiosum ductus deferens epididymis

corpus spongiosum

Fertilization generally occurs in the ________. uterus ovary fallopian tubes vagina

fallopian tubes

Spermiogenesis involves the ________. formation of a functional sperm by the stripping away of superfluous cytoplasm formation of four haploid cells from a spermatogonium movement of sperm in the female genital tract sequence of events in the rete testis

formation of a functional sperm by the stripping away of superfluous cytoplasm

Spermatogenesis ________. is the process of releasing mature sperm cells into the lumen of the seminiferous tubule involves a kind of cell division limited to the gametes uses mitosis to produce gamete cells results in the formation of diploid cells

involoves a kind of cell division limited to the gametes

The hypothalamic-pituitary-gonadal axis ________. involves a positive feedback loop control of spermatogenesis is the tight relationship between the cortex and the control of testicular function involves FSH and LH release involves posterior pituitary release of regulating hormones

involves FSH and LH release

Erection of the penis results from ________. parasympathetic activation of the bulbourethral glands dilation of the veins in the penis a sympathetic reflex a parasympathetic reflex

parasympathetic reflex

The primary function of the uterus is to ________. synthesize female hormones protect the ovaries receive, retain, and nourish a fertilized ovum regulate the ovarian and menstrual cycles

recieve retain and nourish a fertilized ovum

Which of the following phases or processes in the monthly reproductive cycle of the female occur simultaneously? regression of the corpus luteum and a decrease in ovarian progesterone secretion maximal steroid secretion by the corpus luteum and menstruation early follicular development and the secretory phase in the uterus maximal LH secretion and menstruation

regression of the corpus luteum and a decrease in ovarian progesterone secretion

Which of the choices below is not a function of the vagina? serves as a passageway for the primary oocyte receives semen from the penis during sexual intercourse serves as a passageway for menstrual flow serves as the birth canal

serves as a passageway for the primary oocyte

Why doesn't semen enter the urinary bladder during ejaculation? Ejaculation is a parasympathetic reflex resulting in no response by urinary contraction muscles. The smooth muscle sphincter at the base of the urinary bladder closes. There is no urge to urinate during sexual intercourse because of the suppression of LH by testosterone buildup in the blood. There is no common duct between the reproductive system and the urinary system.

tEH SMOTTH MUSCHLE SPHICTER AT THE BASE OF OTHE URINARY BALDDER CLOSES

Which of the following glands are responsible for 70% of the synthesis of semen? the prostate the pituitary the seminal vesicles the bulbourethral glands

the seminal vesicles

How do the testes respond to exposure to excessive body warmth? Excessive warmth has no effect on the testicles because of their location in the scrotum. Excessive warmth is actually beneficial in that it speeds up the maturation of sperm. They move away from the pelvic cavity. They move close to the pelvic cavity.

they move away from the pelvic cavity

If gametes were diploid like somatic cells, how many chromosomes would the zygote contain? twice the diploid number, and with every succeeding generation, the chromosome number would continue to double and normal development could not occur There is no relationship between gametes and somatic cells. half the diploid number with no change in development triple the diploid number, and with every succeeding generation, the chromosome number would continue to triple and normal development would not occur

twice the diploid number, and with every succeeding generation, the chromosome number would continue to double and normal development could not occur

The most important risk for testicular cancer in young males is ________. sexually transmitted infections a diet high in fat undescended testes smoking
