Reproduction lecture ii Flashcards
testis originates within the _ region as _ structures
w/in the abdominal region as retroperitoneal structures
testis descends into the _ by sliding under the peritoneum
scrotum
testes are suspended in the scrotum by the _
spermatic cord
the _ is a membrane surrounding the testis that forms a fluid-filled cavity btwn its visceral and parietal layers
tunica vaginalis
deep to the tunica vaginalis, the testes have a tough, fibrous outer surface called the _, from which septa (walls) extend to form spaces that contain _
tunica albuginea, seminiferous tubules
sperm must move through a series of ducts to get to the epididymis, from seminiferous tubules to _ to _
to rete testis to efferent ductules
epididymis located on _ surface of testis
posterior surface of testis
t/f: epididymis consist of head, body, and tail
true
epididymis is the site of most
sperm maturation and storage
epididymis receives sperm from _
efferent ductules
inguinal canal: has _ passage through _ part of abdominal wall
oblique passage through inferior part of abdominal wall
inguinal canal lies _ and _ to medial half of inguinal ligament (which is the underturned, inferior edge of the aponeurosis of the external oblique muscle)
lies parallel and superior
inguinal canal contains _ (male) or _ (female)
spermatic cord (male) or round ligament of uterus (female)
the _ is the inguinal canal entrance and the _ is its exit
deep inguinal ring is its entrance and the superficial inguinal ring is its exit
spermatic cord suspends testis in _ and carries structures to and from testis
scrotum
spermatic cord begins at _, passes through the inguinal canal, and ends in the _
begins at deep inguinal ring and ends in the scrotum
spermatic cord contains (7)
- ductus deferens
- testicular artery and artery of ductus deferens
- cremasteric artery
- pampiniform venous plexus
- sympathetic nerve fibers
- genital branch of genitofermoral nerve
- lymphatic vessels
ductus deferens (vas deferens) - a muscular tube that conveys sperm from _ to _
sperm from epididymis to ejaculatroy duct
ductus deferens (vas deferens)- terminates as the _
as the ampulla of the ductus deferens
testicular artery branches from _ in abdominopelvic cavity and supplies _ and _
branches from aorta; supplies testis and epididymis
pampiniform plexus - drains to the _ vein
testicular vein
right testicular vein (or ovarian vein) in turn drains to the to the _ whereas the left testicular vein (or ovarian vein) in turn drains to the _
right testicular vein drains to the inferior vena cava, left testicular vein drains to the left renal vein
prostate gland located surrounding the _ after it leaves the urinary bladder
urethra
prostate gland has a _ part and a _ part
glandular and a fibromuscular part
prostate gland produces _ fluid
prostatic fluid
prostate gland its enlargement may impede _
urinary flow
seminal glands are elongated structures located btwn _ and _
btwn urinary bladder and rectum
seminal glands secrete _ fluid
alkaline fluid
the duct of the seminal gland joins the ductus deferens to form the _
ejaculatory duct
t/f: bulbo-urethral (Cowper’s) glands are unpaired, pea-sized glands
false; PAIRED, pea-sized glands
bulbo-urethral (Cowper’s) glands are located _ to the intermediate part of the urethra
posterolateral
bulbo-urethral (Cowper’s) glands produce _ during sexual arousal
mucous-like secretion
ejactulatory ducts: paired and each terminates by emptying into the _
prostatic urethra
what are the 2 common names given to the female external genitalia
- vulva
2. pudendum
what are the 5 parts to the female external genitalia
- mons pubis
- labia majora
- pudendal cleft
- labia minora
- clitoris
mons pubis
rounded, fatty prominence anterior to the pubic symphysis
labia majora
skin folds protecting the external urethral and vaginal orifices
pudendal cleft
depression btwn the labia majora
pudendal cleft contains the
labia minora
labia minora
fat-free, hairless skin folds that are enclosed w/in the pudendal cleft and labia majora
labia minora surrounds the
vestibule of the vagina
clitoris erectile organ consisting of:
erectile organ consisting of glans (covered by prepuce), body, and paired crura (attached to the inferior rami of the pubic bones)
vestibule of the vagina: space surrounded by
the 2 labia minora
vestibule of the vagina: contains
vaginal orifice, external urethral orifice, and ducts of the greater and lesser vestibular glands
vestibule of the vagina: contains hymen which is a thin fold of
mucous membrane that may partially or wholly occlude the vaginal orifice
greater vestibular (Bartholin) glands: on each side of the _ of the vagina, _ to the vaginal orifice
on each side of the vestibule of the vagina, posterolateral to the vaginal orifice
greater vestibular (Bartholin) glands: secrete _ into the vestibule for lubrication
mucous
ovaries are _-shaped and -sized
almond-shaped and -sized
mesovarium short peritoneal fold that suspends _ in abdominopelvic cavity
ovary
mesovarium is a subdivision of a
larger mesentery, the broad ligament of the uterus
suspensory ligament of the ovary: peritoneal fold w/in which the _ vessels and _ travel to and from _
the ovarian vessels and nerves travel to and from ovary
suspensory ligament of the ovary: this ligament becomes continuous with the _
mesovarium
