Anatomy & Physiology 2- Chapter 26: The Reproductive System

True or False: At three months of development, the connective tissue bands elongate as the fetus grows.

False

True or False: At three months of development, the relative position of the testes does not change.

False

True or False: At two months of development, the testes form inside the scrotal sac.

False

True or False: Decreased sexual function in men typically occurs after vasectomy

False

True or False: Emission in male sexual activity is controlled by somatic motor neurons in the lower lumbar and upper sacral segments of the spinal cord.

False

True or False: Emission in male sexual activity is due to parasympathetic activation.

False

True or False: Emission in male sexual activity stimulates the bulbo-urethral glands.

False

True or False: If fertilization does not occur, a layer of thecal cells forms around the follicle.

False

True or False: If fertilization does not occur, the tertiary follicle initially collapses and under LH stimulation, forms the corpus luteum.

False

True or False: If fertilization does not occur, the tertiary follicle releases the secondary oocyte with its protective outer covering, the corona radiata, into the pelvic cavity

False

True or False: More than 95 percent of testicular cancers result from abnormal nurse cells

False

True or False: Screening with periodic PSA tests is recommended for testicular cancer

False

True or False: Spermatozoa do not continue to develop after surgical sterilization is complete.

False

True or False: The average age at the time of diagnosis for testicular cancer is 18 years.

False

True or False: The failure rate is extremely high with surgical sterilization in males

False

True or False: The uterine glands enlarge, accelerating their rates of secretion during menses

False

True or False: There is a degeneration of the basilar zone and the deepest uterine glands during menses

False

True or False: menses begins at the time of ovulation and persists as long as the corpus luteum remains intact

False

During the follicular phase of the ovarian cycle:

developing follicles secrete estradiol.

Which region is the rounded portion of the uterine body superior to the attachment of the uterine tubes?

fundus

Gardasil is a vaccine against ______, which is responsible for 75 percent of cervical cancers.

human papillomavirus

Throughout childhood, the vagina and vestibule are usually separated by which structure?

hymen

Which structure surrounds the tip of the penis, attaches to the relatively narrow neck of the penis, and continues over the glans?

prepuce

Which ovarian structure remains in a state of suspended development until the individual reaches puberty?

primary oocyte

During the luteal phase of the ovarian cycle, __________.

progesterone secretion by the corpus luteum stimulates endometrial growth and secretion

The bulbo-urethral glands:

secrete a thick, alkaline mucus that helps neutralize any urinary acids.

Within which structure does sperm production occur?

seminiferous tubule

In which process does a spermatozoon lose its attachment to the nurse cell?

spermiation

Which structure is associated with the formation of primary follicles?

zona pellucida

True or False: Emission in male sexual activity begins with peristaltic contractions in the ampullae of the ductus deferens.

True

True or False: If fertilization does not occur, the corpus albicans is formed.

True

True or False: In a vasectomy, each ductus deferens is cut, and either a segment is removed (and the ends tied or cauterized), or silicone plugs are inserted

True

True or False: Late in fetal development, each testis is pulled through the abdominal musculature into the scrotum.

True

True or False: The 5-year survival rate for localized testicular cancer is 99%.

True

True or False: menses marks the beginning of the uterine cycle

True

Within spaces between the seminiferous tubules, the interstitial endocrine cells __________.

are responsible for the production of androgens

Which structure is an extensive mesentery that attaches to the sides and floor of the pelvic cavity?

broad ligament

Which male accessory organ functions as the site of sperm maturation?

epididymis

Which male reproductive structure is the start of the male reproductive tract in which spermatozoa exist in a sheltered environment that is precisely regulated by the surrounding epithelial cells?

epididymis

stress and anxiety can make it difficult to become sexually aroused, because those emotions

inhibit parasympathetic reflexes

Testosterone injections could lower sperm count by

inhibiting release of GnRH

Which birth control method may utilize copper ions to inhibit sperm motility?

intrauterine device (IUD)

The recto-uterine pouch:

is formed between the posterior wall of the uterus and the anterior surface of the colon.

Near the nipple, each lactiferous duct enlarges, forming an expanded structure called a:

lactiferous sinus

Which function is a peripheral effect of testosterone?

maintenance of accessory glands and organs of the male reproductive system

Which stage of spermatogenesis yields four immature (undifferentiated) haploid cells?

meiosis II

Which uterine structure provides much of the force needed to move a fetus out of the uterus and into the vagina?

myometrium

Which regional structure of a sperm contains both centrioles of the original spermatid?

neck

Regarding the proliferative phase of the uterine cycle:

the uterine glands are manufacturing a glycogen-rich mucus that can be metabolized by an early embryo.

tunica albuginea

tough fibrous capsule that covers the testis (continuous with septa testis

Which structure is continuous with the septa that subdivide the interior of the testis into separate lobules?

tunica albuginea
