The Reproductive System

Question 1

Pelvic Inlet

Answer 1

Where the demarcation between the abdominal and pelvic cavities occur
- Transverse plane that crosses the superior borders of the pubis and sacrum

Question 2

Testes

Answer 2

Organs of male reproductive system responsible for spermatozoa production and the primary testosterone source in males

Question 3

Scrotum

Answer 3

Where the testes descend and reside during development

Question 4

Spermatic Cord

Answer 4

Conduit between the scrotum and abdominopelvic cavity

Question 5

Cremaster Muscle

Answer 5

Contracts and relaxes (scrotum), elevating and lowering the testes
- Contraction: When testes is too cold and needs to be warmed (elevation)
- Relaxing: When testes is too warm and needs to be cooled (lowering)

• regulates temperature of testes

Question 6

Testicular Artery

Answer 6

Brings blood from the aorta and is surrounded by the veins pampiniform plexus

Question 7

Testicular Vein

Answer 7

Formed from the network of veins (pampiniform plexus) on each side of body

Question 8

Testicular Vein

Answer 8

Formed from the network of veins (pampiniform plexus) on each side of body

Question 9

Rete testis

Answer 9

Tubule network that collects sperm from several seminiferous tubules

Question 10

Efferent Ductules

Answer 10

Outside the testis and carries sperm to the epididymis

Question 11

Epididymis

Answer 11

Long coiled tube that lies across the testis

Question 12

Ductus Deferens (vas deferens)

Answer 12

Where the epididymis terminates and carries sperm up through the spermatic cord through the pelvic cavity to ultimately joint the urethra

Question 13

Perineal Muscles

Answer 13

Contracts in pelvic floor to propel semen through the urethra during ejaculation

Question 14

Ejaculatory Duct

Answer 14

Formed by fusion of the 2 seminal vesicles with a ductus deferents and travel through prostate to join urethra

Question 15

Seminal Vesicles’ Fluid

Answer 15

Provides energy to sperm cells as fructose and contain buffers to neutralize the vagina’s acidic environment

Question 16

Prostate

Answer 16

Gland that make prostatic fluid and is home to the prostatic urethra and the 2 ejaculatory ducts that join it

Question 17

(2) Bulbourethral Glands

Answer 17

Found in the pelvis’s muscular floor and each have a short duct that connects to the membranous urethra
- Basic mucus to allow sperm to go through acidic vagina

Question 18

Chambers of Erectile Tissue

Answer 18

Corpora Cavernosa: Paired upper chambers that attach to the inferior rami of pubic bones
Corpus Spongiosum: Surrounds the urethra as it emerges from the flood of the pelvis and enlarged at the distal end of the penis forming the glans region

Question 19

Glans

Answer 19

Expansion of the corpus spongiosum and the opening of the urethra is found at its center

Question 20

Penis

Answer 20

Made of erectile tissues that expand with blood during erection by dilation of arteries and constriction of veins

Question 21

Ovaries

Answer 21

Produce oocytes (egg cells) that travel through uterine tubes to the uterus

Question 22

Vagina

Answer 22

Leads to the exterior of the body from the uterus. Receives penis during sex and birth canal.

Question 23

Uterus

Answer 23

Allows for implantation and the formation of a placenta
(upper fundus, middle body, lower cervix)

Question 24

Infundibulum

Answer 24

Where ovulated oocytes are swept into by its finger-like fimbriae
- uterine tube

Question 25

Fimbriae

Answer 25

Finger like projections of the infundibulum

Question 26

Where does Fertilization occur

Answer 26

Infundibulum or the ampulla

Question 27

Isthmus

Answer 27

Formed by the narrowing of the uterine tube

Question 28

Ampulla

Answer 28

Slightly enlarged region of the uterine tube b/w isthmus and infundibulum

Question 29

Cervical Canal’s 2 Ends

Answer 29

Internal os (opening) and external os

Question 30

3 Layers of the Uterus

Answer 30

Endometrium, myometrium, perimetrium

Question 31

Endometrium

Answer 31

Innermost layer of the uterus that is shed with each menstrual cycle and regenerated for next cycle. Placenta.

Question 32

Myometrium

Answer 32

Middle and most substantial layer of the uterus made of smooth muscle that contracts during labor to push the fetus through the cervical canal

Question 33

Perimetrium

Answer 33

The outermost layer of the uterus and made of parietal peritoneum and found where the uterus bulges into the peritoneal cavity

Question 34

Perimetrium

Answer 34

The outermost layer of the uterus and made of parietal peritoneum and found where the uterus bulges into the peritoneal cavity

Question 35

Labia Majora

Answer 35

Skin covered part of the vulva

Question 36

Vulva

Answer 36

The external genitalia

Question 37

Labia Minora

Answer 37

Internal to the labia majora and covered by mucose which merge anteriorly to form the hood of the clitoris

Question 38

Clitoris

Answer 38

Small erectile organ derived from an embryological structure that forms the penis in males

Question 39

Glans (female)

Answer 39

Only visible part of the clitoris

Question 40

External urethral orifice

Answer 40

Posterior to the glans of the clitoris and is followed by the vaginal orifice

Question 41

Pampiniform Plexus

Answer 41

Network of veins that cool the incoming arterial blood, thereby lowering the testis’ temperature.
