Q

venous drainage of bladder

A

does not correspond w/arterial supply
into dense venous plexus around the base and neck
prostatic plexus in males
vesico-vaginal plexus in female
drains w/deep dorsal v of penis to iliac v

Q

pelvic ureter relationships

A

enters pelvis by crossing iliac vessels anteriorly
male- ductus deferens cross ant to ureter
female- uterine a crosses ureter ant/sup

Q

penile urethra dilations

A

w/in bulb- bulbar

w/in glans penis- fossa navicularis

17
Q

glands into penile urethra

A

bulbourethral

urethral

18
Q

female urethra parts

A

superior- surrounded by urethral glands (homologous to prostate)
membranous- in UGD

19
Q

rectum different from sigmoid?

A

no mesocolon -> retroperitoneal

teniae coli spread out as longitudinal mm surrounding entire rectum

20
Q

rectum proper

A

from origin to perineal flexure

dilated caudel portion is ampulla

21
Q

anal canal

A

perineal flexure to anus
anatomical- from level of upper surface of pelvic diaphragm to anus
clinical- from pectinate line to anal verge

22
Q

structures of rectovesicle pouch

A 
palpable
posterior surface of bladder
seminal vesicles
distal vas deferens
prostate
sacrum, coccyx, ischial spines
23
Q

structures of rectouterine pouch

A

cervix
vagina
sacrum, coccyx, ischial spines

24
Q

layers of rectum

A

-mm:
outer longitudinal- blends w/levator ani at anal region
inner circular- thickens to form internal spinchter
-submucosal
-mucosal

25
Q

plica transversales

A 
aka transverse rectal folds
semilunar folds of mucosa, submucosa, and circular m
2 left
1 right
lowest 2" above anus
highest at rectosigmoid jnx
26
Q

rectal columns

A

mucous membrane overlying submucosal aa and vv

27
Q

anal valves

A

arch-like folds of mucous membrane connecting caudel ends of rectal columns
cover anal sinues

28
Q

pectinate line

A

irregular circumrential line formed by anal valves and base of rectal columns
venous drainage- superior to middle and superior rectal vv, inferior to inferior rectal vv
lymp- superior to pelvic nodes, inferior to inguinal nodes
nn- superior autonomic, inferior voluntary
epi- superior typical GI, inferior stratisfied squaous

29
Q

pecten

A

area immediately below pectinate line

characterized by a lot of CT creating blue-white appearance

30
Q

anal verge

A

caudal most portion of anal canal

skin picks up sweat glands and hair

31
Q

superior rectal a

A

from inferior mesenteric

does not supply upper 1/5- 1/4 rectum

32
Q

middle rectal a

A

highly variable in origin from internal iliac or other pelvic aa
distributed primarily to mm of rectum

33
Q

inferior rectal a

A

from internal pudendal aa

supply external anal spinchter and perianal portion of levator ani

34
Q

submucosal plexus

A

aka subcutaneous plexus
w/in submucosa immediately under skin of anal canal
superior rectal v above pectinate line
inferior rectal v below pectinate line

35
Q

perimuscular plexus

A

drains muscular wall of rectum below level of peritoneum

mostly drains into middle rectal vv
