A

levator ani and coccygeus

20
Q

largest muscle in the urogenital diaphragm, fills the deep perineal pouch

A

posterolateral

22
Q

ureters in the female cross __ and in males cross __

females it crosses uterine artery

males ureters cross ductus deferens

23
Q

urinary bladder stores urine prior to expulsion thru urethra, consists of smooth muscle called

A

detrusor urinae

24
Q

an organ found in males which is in between the bladder and perineum which the urethra passes through the gland

25
combination of the urogenital tracts in the male
prostatic part of urethra
26
rectum is located in the true pelvis superior to the pelvic floor, normally constricted by
puborectal sling (U shaped puborectalis m.)
27
continuous with rectum at anorectal junction and produces curvature at anorectal junction (perineal flexure)
anal canal
28
fascial sheath derived from anterior abdominal wall. from inguinal canal into scrotum
spermatic cord
29
spermatic cord surrounds what structures
surrounds ductus deferens, testicular vessels and nerves
30
2 pea sized glands within urogenital diaphragm, empty into penile urethra
bulbourethral (cowper's) gland
31
the __ of the epididymis is continuous with the vas deferens
tail
32
primary reproductive organs of female
ovaries
33
muscular tubes for transport of ovum to uterus, open canal from peritoneal cavity to uterus
uterine (fallopian) tubes
34
uterine tubes are open channels from peritoneal cavity to uterus and are made up of fimbriae, __,__,__
infundibulum, ampulla, isthmus
35
usually anteverted and at right angle to vaginal canal, can enlarge 20x during pregnancy
uterus
36
inferior neck of uterus protruding into vaginal canal, opens to vagina as external os and uterus as internal os
uterine cervix
37
circular gutter surrounding cervix, deeper posterior than anterior
vaginal fornix
38
uterine ligament that is peritoneum covering ovarian vessels and nerves
suspensory ligament
39
uterine ligament that is peritoneum covering uterus and uterine tube, ovaries
broad ligament
40
uterine ligament that anchors ovary to uterus
ovarian ligament comes from gubbernaculum embryro
41
uterine ligament, continuous of ovarian ligament, passes thru inguinal canal to fuse with labia majora
round ligament of the uterus
42
posterior extension of the broad ligament (uterine)
mesovarium
43
portion of male urethra passing through perineal membrane leading into the spongy part of the urethra
membranous part of urethra
