- fimbriae
24
Q
uterus ligaments (3)
A
- uterosacral ligament
- cardinal ligament
- round ligament
25
ovaries
- paired almond shaped organs
- produce ova (eggs)
- secrete estrogen and progesterone
26
vagina
- open to external environment
- begins at the external os of the cervix
- posterior to bladder
- protrusion of cervix creates fornixes
27
Male pelvic viscera
- ductus deferens
- seminal vesicles
- ejaculatory ducts
- prostate gland
28
ductus (vas) deferens
- bladder
- ureter
- ductis deferens
- ampulla
29
seminal vesicles
- posterior surface of bladder
- lateral to ductus deferens
- glandular structures
- stores and produces fluid that makes up a majority of semen
30
ejculatory ducts
- formed by the union of the seminal vesicles and ducts deferens
31
prostate gland
- inferior to bladder
- walnut shaped
- transvered byt he prostatic urethra
- prostatic uricle contracts to widen the openings of the ejaculatory ducts
32
sigmoid colon
- "S" shaped
- distal end of colon
- continuous with the rectum distally
33
Rectum
- continuous with the anal canal distally
- two flexures: 1) sacral flexure 2) anorectal flexure
34
rectum - internal anatomy
- 3 transverse folds (superior, middle, inferior rectal folds)
- 3 lateral flexures
35
ureters
- exit renal pelvis
- pass posterior to gonadal vessels and anterior to psoas major
- pass anterior to iliac vessels
- enter the posterior aspect of the bladder
36
bladder
- apex
- body
- ureters
- ureteric orifices
- internal urethral orifice
- urethra
- trigone (not a structure)
37
blood supply
- common iliac artery
- internal iliac artery
- external iliac artery
- gonadal arteries
- inferior mesenteric artery
- common iliac artery
38
uterus blood supply
- uterine artery
- internal iliac artery
39
ovaries blood supply
- abdominal aorta --> right or left ovarian artery
40
rectume blood supply
- inferior mesenteric artery
- superior rectal artery
- internal iliac artery
- middle rectal artery
- inferior rectal artery
41
pelvic viscera is innervated by the ____ nervous system: sympathetic and parasympathetic
autonomic
42
sympathetic innervation pathway
preganglionic neurons in L1 and L2 --> inferior hypgastric or inferior mesenteric ganglion --> pelvic viscera
43
Sympathetic innervation: Pelvic viscera _____ the bladder, ____ the internal urethral sphincter -- prevents ____

45
Sympathetic innervation: Pelvic viscera _____ uterine contraction
excites
46
parasympathetic innervation pathway
preganglionic neurons: S2, S3, S4 --> pelvic splanchic nerves --> pelvic viscera
