Q

the male bladder borders

A

the bladder rests against the pubis, and its upper surface, which is covered by peritoneum, is bordered by abdominal viscera.
The posterior aspect (or base) of the bladder, in males, is partially separated from the rectum by the rectovesical pouch.
In males, the neck of the urinary bladder (where the urethra begins) rests on the prostate gland

Q

the female bladder borders

A

the bladder rests against the pubis, but is bordered by the uterus superiorly and by the vagina posteriorly
In females (there is no prostate gland), the urethra leaves the neck of the bladder to pass into the fascial tissue covering the anterior wall of the vagina.

Q

what is the trigone of the bladder

Study These Flashcards
A

ureteric orifices and internal urethal orifice

23
Q

where does the prostatic urethra begin

Study These Flashcards
A

trigone of the bladder

24
Q

where does the prostatic uretha run to

Study These Flashcards
A

the region of sphincter urethra muscle (or external urethral sphincter) where it is called membranous uretha

25
when is the prostatic urethra called the spongy urethra
As the urethra enters the bulbus penis
26
what is the urethral crust
a central vertical ridge on the posterior wall of the prostatic urethra. Its central part is expanded to form the colliculus semilunaris
27
what is the prostatic utricle
A vertical slit in the center of the colliculus,
28
what are the openings of the ejaculatory ducts
seen as vertical slits on the colliculus on each side of the opening of the prostatic utricle.
29
what are the prostatic sinuses
grooves on either side of the urethral crest; this is where the numerous ducts of the prostate gland enter the urethra.
30
what sphincter is striated muscle in the female urethra
the external urethral spincter
31
where is the external urethral orifice located
in the vestibule of the cagina a region bounded by labia minora
32
rectum connects, begins and ends where?
the sigmoid colon to the anal canal  Begins at the level of the sacral promontory and ends at the level of the levator ani
33
where does the rectum begin
third segment of the sacrum
34
whats the arterial supply to the rectum
comes from superior rectal artery and middle rectal arteries
35
the superior rectal artery is the terminal branch of the
inferior mesenteric artery
36
what are the male reproductive structures and what supplies them
ductus deferens, seminal vesicle, ejaculatory duct supplied by superior and inferior vesicle arteries
37
ductus deferens
Has relatively thick muscular walls Begins in the tail of the epididymis Conveys sperms to the ejaculatory duct
38
seminal vesicle
is a long, coiled, tube-like, glandular structure that secretes part of the seminal fluid does NOT store sperm
39
ejaculatory duct
Duct of the seminal vesicle/gland with the ampulla of the ductus (vas) deferens Opens into the prostatic urethra
40
prostate
Two thirds is glandular and the other third is fibromuscular.  Secretes an alkaline solution protective for sperm The prostatic urethra and two ejaculatory ducts traverse it Situated inferior to the bladder Supplied by the inferior vesical artery
41
bulbourethral glands
Largely embedded within the external urethral sphincter The ducts open in the proximal part of the spongy urethra Produce a mucus-like secretion which neutralizes the acidic urine in the urethra Supplied by branches off the internal pudendal artery
42
parts of the uterus
fundus:superior to uterine tubes body cervix (supravaginal part and vaginal part) wall of uterus (perimetrium, myometrium, endometrium)
43
ligaments of the uterus
broad ligament round ligament transverse cervical uterosacral
44
broad ligament
Double fold of peritoneum-divided into 3 parts Provides passive support to the uterus Extends from sides of uterus to lateral walls and floor of pelvis Laterally it becomes the suspensory ligaments Divided into: Mesovarium: contains the ovaries Mesosalpinx: contains the uterine tubes Mesometrium: mesentery of the uterus
45
rounds ligament of the uterus
Body of uterus to labia majora-remnant of female gubernaculum Helps maintain the anteversion position of the uterus during pregnancy
46
transverse cervical ligament
From the cervix and lateral parts of the vaginal fornix to the lateral walls of the pelvis Transmits uterine vessels
47
uterosacral ligament
Posteriorly from sides of cervix to the middle of the sacrum Provides passive support to the uterus
48
uterine tubes
extend from the uterus to the ovaries infundibulum, ampulla, isthmus, uterine part
49
ovaries are suspended by the
mesovarium: portion of broad ligament Suspensory ligaments: attachment to pelvic wall Ligament of the ovary (ovarian ligament): attachment to uterus
50
ovaries are supplied
the ovarian (from aorta) and uterine arteries (from internal iliac)
51
what do the ovarian arteries travel within
the suspensory ligament
52
vestibule contains
the vaginal and urethral orifices openings of the greater vestibular glands
53
vascular supply of the vagina
uterine arteries supply the superior part vaginal artery and internal pudendal supply middle and inferior parts
