S. T., tumulus rectus, rete testis, epididymus, vas deferens, ejaculatory duct, urethra

Front 5

Name the three erectile bodies in the penis

Back 5

Corpus Spongiosum, Corpora cavernosa

Front 6

Starting in the ovary, trace a pathway to the outside world

Back 6

Uterine tube(fimbria, infundibulum, ampulla, isthmus), uterus, cervical canal, vagina

Front 7

What does the Greek word salpinx mean?

Back 7

Trumpet, as in fallopian tube

Front 8

Name the three layers of the uterus

Back 8

Perimetrium, myometrium, endometrium

Front 9

Which layer of the endometrium is shed during menstruation

Back 9

Stratum functionalis

Front 10

Name the three phases of the uterine cycle

Back 10

Menstrual, proliferative, secretory

Front 11

Where are interstitial cells located? What is their function?

Back 11

Interstitial cells are clusters in the loose connective tissue between the seminiferous tubules. The cells secrete testosterone.

Front 12

What is meant by the phrase, “sperm mature in the epididymis”?

Back 12

In the epididymis, sperm gain the ability to swim in the ability to fertilize egg

Front 13

Where is the ejaculatory duct located?

Back 13

The ejaculatory duct is located at the junction of the ampulla of the ductus deference and the duct of the seminal gland. This duct passes through the prostate and empties into the prostatic urethra.

Front 14

Which pair of accessory glands produces a majority of the semen

Back 14

Approximately 60% of the volume in semen is produced by the seminal glands

Front 15

Which erectile tissue does the urethra pass through? What is this portion of the urethra called?

Back 15

Do you read the passage through the corpus spongiosum and thus this portion of the urethra is called the spongy urethra

Front 16

Which erectile tissue does the urethra pass through? What is this portion of the urethra called?

Back 16

Do you read the passage through the corpus spongiosum and thus this portion of the urethra is called the spongy urethra

Front 17

How many spermatids are formed from each primary spermatocyte?

Back 17

Each primary spermatocyte produces four spermatids

Front 18

Which erectile tissue does the urethra pass through? What is this portion of the urethra called?

Back 18

The urethral passage through the corpus spongiosum and thus this portion of the urethra is called the spongy urethra

Front 19

How many spermatids are formed from each primary spermatocyte?

Back 19

Each primary spermatocyte produces four spermatids

Front 20

What roles do sustentocytes play in sperm formation

Back 20

Sustentocytes help to form sperm by nourishing spermatogenesis cells and moving the cells toward the tubular lumen. Secretion from Sustentocytes influence testosterone and FSH levels and function either to stimulate or to inhibit sperm formation. Tight junctions between adjacent sustentocytes form the blood testis barrier, which prevents sperm from attack by the immune system.

Front 21

What are the components of the head of the sperm? of the midpiece? of the tail?

Back 21

The head of the sperm contains the nucleus and the acrosome. the midpiece contains mitochondria and tail is a flagellum

Front 22

What type of tissue lines the uterine tubes? How does this aid in capturing the ovulated oocyte?

Back 22

The uterine tubes are lined with ciliated and unciliated columnar epithelium. The beating of the cilia produces movement of the peritoneal fluid to draw the oocyte into the uterine tube.

Front 23

Names of peritoneal supports of the female reproductive structures. To which organ does each attach

Back 23

peritoneal folds that support the female reproductive structures are the broad ligament composed of the mesometrium to the uterus, the mesosalpinx to the uterine tubes, and mesovarium and suspensory ligament to the ovary

Front 24

Describe the location of each of the following structures:(a). fundus of the uterus (b). infundibulum to the uterine tube (c). endometrium

Back 24

(A) the fundus of the uterus is the region superior to the entrance of the uterine tubes

(B). the infundibulum is the lateral funnel shaped opening of the uterine tube

(C). the endometrium is the innermost layer of the uterine wall

Front 25

Which hormone stimulates follicle development in the ovaries

Back 25

Follicle-stimulating hormone stimulates follicle development in the ovary

Front 26

During which period of a females life, do stem cells, oogonia, produce oocytes? does this differ from spermatocyte production in males?

Back 26

Oogonia Differentiate into oocytes during the fetal period in females. In males, spermatogonium differentiate into spermatocytes throughout a males adult

Front 27

What is the corpus luteum and what role does it play in the ovarian and uterine cycle?

Back 27

The corpus luteum is a remnant of the ovarian follicle after ovulation. the corpus luteum secretes progesterone, which stimulates the secretory phase of the uterine cycle

Front 28

What is the corpus luteum and what role does it play in the ovarian and uterine cycle?

Back 28

The corpus luteum is a remnant of the ovarian follicle after ovulation. the corpus luteum secretes progesterone, which stimulates the secretory phase of the uterine cycle

Front 29

What are the medical modulus of the following female genitalia structures:(a) labia majora, (b). major clitoris (c). bulb of the Vestibule

Back 29

A. The female labia majora are homogolous to the males scrotum

B. The clitoris is homogolous to the corpora cavernosa of the penis.

C. The bulb of the vestibule is homogolous to the corpus spongiosum

Front 30

When does the glandular portion of the breast develop in females

Back 30

The glandular portion of the breast develops midway through pregnancy
