parasympathetics- vagus?

19
Q

male internal repro organs

A

inferior hypogastric plexus -> subsidiary plexuses
sympathetics- T12-L2 lumbar and sacral splanchnics, stimulates emission
parasympathtics- S2-4 pelvic splanchnics

20
Q

penis and glands of perineum

A

dorsal n of penis- sensory and sympathetics

cavernous nn- parasympathetic nn from prostatic plexus

21
Q

ovaries and uterine tube

A

ovarian plexus
sympathetics- T10-11 lesser splanchnic n and aorticorenal ganglion, vasomotor
parasympathetic vagus?

22
Q

uterus, cervix, superior vagina

A

inferior hypogastric plexus -> uterovaginal plexus
sympathetics- T12-L2 lumbar and sacral splanchnics
parasympathetics- S2-4 pelvic splanchincs (contraction of smooth m)

23
Q

inferior vagina

A

pudendal nerve

24
Q

rectum and anal canal superior to pectinate line

A

inferior hypogastric plexus -> rectal plexus
sympathetic - L1-2 lumbar and sacral splanchnics, vasomotor and inhibit gland secretion
parasympathetic- S2-4 pelvic splanchnics, peristalsis, stimulate glandular secretion

25
Q

anal canal inferior to pectinate line

A

inferior rectal nn

26
Q

pelvic pain line

A

superior visceral pain travels w/sympathetics to T11-L2

inferior (sub-peritonealized organs) visceral pain travels w/parasympathetics to S2-4 via pelvic splanchnics

27
Q

pain ureter

A

w/sympathetics

28
Q

pain superior bladder

A

peritonealized

sympathetics to T10-L2

29
Q

pain inferior bladder

A

subperitonealized

parasympathetics pelvic splanchnics to S2-4

30
Q

pain urethra

A

parasympathetics

31
Q

pain rectum

A

parasympathetics S2-4

32
Q

pain anal canal

A

above pectinate line- parasympathetics to S2-4

below pectinate line- somatic pudendal n

33
Q

pain male internal repro organs

A

parasympathetics to S2-4

34
Q

pain testes, epididymis, distal ductus deferens

A

sympathetics, T10-11

35
Q

pain penis

A

somatic pudendal n

36
Q

pain ovary and uterine tubes

A

sympathetics T10-11

37
Q

pain uterus

A

fundus and body- sympathetics T12-L2

cervix- parasympathetics S2-4

38
Q

pain vagina

A

superior- parasympathetics S2-4

inferior- somatic, pudendal

39
Q

lumbar epidural

A

LV3/4 level of anesthesia 3-4 times higher then insertion
complete anesthesia of penis, perineum, and LL
mother will not feel pain from uterine contractions or passage of infant thru birth canal
can be continuously delivered via indwelling cather

40
Q

caudel epidural

A

into sacral canal
S2-4 cord levels
loss of pain from cervix, vagina, perineum, can still feel uterine contractions

41
Q

pudendal nerve block

A

loss of feeling rom inferior vagina and perineum
pain from uterine contraction and passage thru birth canal still felt
pudendal n localized by palpating ischial spine and sacrospinous lig
minimizes pain from potential tearing or episiotomy
