30
Once pelvic splanchnic nn enter perineum what are they called
cavernous nn
31

inferior hypogastric plexus to the prostatic or vesicle plexus
32
What type of SAN does urethra receive
L1-L3 from lumbar and sacral splanchnics
33
What type of PAN does urethra receive
S2-S4 via pelvic splanchnic nn
34
What somatic nn inn perineal urethra
pudendal n S2-S4
35
What plexus provides inn to testes
testicular plexus
36
What is the SAN to testes
T10-T11 via lesser splanchnic n and aorticorenal ganglion
37
What PAN to testes
likely vagus
38
What plexus provides inn to internal male reproductive organs
inferior hypogastric plexus, subsidiary plexuses
39
What is the SAN to male internal reproductive organs
T12-L2 via lumbar and sacral splanchnics
40
What is the action of SAN on internal male repro organs
emission (part of ejaculation) contraction of sm mm in ductus deferens, seminal glands, ejaculatory duct, prostate leads to delivery of semen to urethra
41
What is the PAN to male internal repro organs
S2-S4 via pelvic splanchnic nn
42
Describe nn that inn penis and glands of perineum
``` dorsal n of penis (Sensory and SAN) cavernouse nn (PAN from prostatic plexus) ```
43
What is the action of nn on penis and glands of perineum
erection (PAN tone to vasodilate by cavernouse nn) contraction of bulbospongiosus and ischiocavernosus mm. (prevents venous drainage)
44
remission of penis is what type of response
SAN involving helicine aa
45
What plexus provides inn to ovaries and uterine tube
ovarian plexus
46
What is the SAN to ovaries and uterine tube and actions
T10-T11 via lesser splanchnic n and aorticorenal ganglion and vasomotor
47
What is PAN to ovaries and uterine tube and actions
vagus and vasomotor
48
Reflexive sensations(distention) travel with what nn
PAN S2-S4
49
What type of nn fibers do afferent pain fibers run with from perineum
PAN and SAN depending on whether organ is above or below pelvic pain line
50
Where is the pelvic pain line
inferior limit of pelvic peritoneum
51
What is the distinguishable fact about organs above or bleow pelvic pain line
covered with peritoneum or not
52
the organs above pelvic pain line have pain fibers where
SAN T11-L2 because peritonealized.
53
the organs below pelvic pain line have fibers where
PAN S2-S4 sub peritoneal
54
Where do pain afferents travel from ureter
SAN
55
Where do pain afferents travel from bladder

PAN S2-S4 | except testes, epididymis, and distal ductus deferens which all travel with SAN T10-T11(testicular plexus)
61
Where do pain afferents travel from penis
pudendal because somatically inn
62
Where do pain afferents travel from ovary and uterine tubes
SAN T10-T11 ovarian plexus

superior 3/4 PAN S2-S4 | inferior 1/4 somatic--> pudendal
65
What is a lumbar epidural
anesthetic delivery to LV3/LV4 level of anesthesia is usually 3-4 levels higher than insertion provides complete anesthesia to pelvis, perineum and lower limbs can be continuously delivered via an indwelling catheter does not have pain from uterine contraction or passage of infant through canal
66
What is a caudal epidural
``` anesthetic delivery into epidural space of sacral anal, anesthesia to S2-S4 numb pain from cervix, vagina, perineum Uterine contractions still felt still can walk cannot feel passage through birth canal ```
67
What is a pudendal nerve block
provides anesthesia of majority of perineum and inferior 1/4 vagina pain from uterine contractions, passage through birth control is felt minimize pain from potential treating or episiotomy
68
Where is a pudendal n localized
palpate ischial spin and sacrospinous ligament
69
what plexus provides inn to uterus, cervix and superior portion of vagina
inferior hypogastric plexus--> uterovaginal plexus
70
Describe SAN inn to uterus, cervix, superior portion of vagina
T12-L2 via lumbar and sacral splanchnic nn | vasomotor
71
descibe PAN inn to uterus, cervix, superior portion of vagina
S2-S4 via pelvic splanchnic nn | vasomotor, contraction smooth mm
72
What somatic n inn last 1/4 vagina
pudendal
73
Describe SAN to rectum and anal canal superior to pectinate line
L1-L2 via lumbar and sacral splanchnic nn | vasomotor , inhibit gland secretion
