27
Q

Where does the superior vesical artery come from?

A

Usually a branch off of the uterine artery

28
Q

Where do the external iliac receive lymph from?

A

inguinal nodes

29
Q

Where do internal iliac nodes receive lymph from?

A

The pelvic viscera and gluteal regions

30
Q

Where do sacral lymph nodes receive lymph from?

A

The postero-inferior pelvic viscera.

31
Q

Were do common iliac nodes receive lymph from?

A

External iliac nodes, internal iliac nodes, sacral nodes,

32
Q

Where do common iliac nodes drain to

A

lumbar nodes

33
Q

What is the pelvic venous plexus?

A

A plexus of veins that surrounds pelvic viscera

34
Q

Where do common iliac veins unite to form the IVC

A

L4/L5, one level lower than aorta

35
Q

Does the lumbar plexus provide innervation to the true pelvis?

A

no, it supplies portions of the perineum and greater pelvis

36
Q

Ilioinguinal nerve (L1)

A

Supplies most of skin of mons pubis and anterior aspect of scrotum/labia majora

37
Q

What supplies the cremaster muscle and skin on the anterolateral aspect of the scrotum/labia majora

A

Genitofemoral (L1-L2)

38
Q

What supplies the motor branches to iliopsoas muscle?

A

Femoral nerve (L2,3,4)

39
Q

What nerve travels through the lesser pelvis but does not arise or innervate structures of the true pelvis

A

Obturator Nerve (L2,3,4)

40
Q

How does the obturator nerve exit the pelvis

A

Via the obturator foramen

41
Q

How is the lumbosacral trunk formed?

A

From descending ramus of L4 and L5

42
Q

What levels is the sacral plexus?

A

L4-S3

43
Q

What general area does the sacral plexus supply?

A

It lies in the pelvis but primarily supplies the lower limb.

44
Q

Nerves from the sacral plexus

A

Nerves to levator ani and coccygeus, nerve to piriformis muscle, pudendal nerve, posterior femoral cutaneous nerve

Sciatic nerve, nerve to obturator internus, nerve to quadratus femoris, superior gluteal nerve, inferior gluteal nerve

45
Q

Where do the nerves to levator ani and coccygeus arise?

A

S3 and S4

46
Q

Where do nerve to piriformis arise?

A

S1 and S2

47
Q

Where does the pudendal nerve arise?

A

S2,3, and 4

48
Q

What type of fibers are included in superior hypogastric plexuses

A

Pre and postganglionic sympathetic fibers and visceral afferents

49
Q

Fiber types found in inferior hypogastric plexuses

A

Pre and postganglionic sympathetic fibers and visceral afferents as well as preganglionic parasympathetic fibers.

50
Q

Fiber types found in pelvic plexuses

A

Postganglionic sympathetic fibers and preganglionic parasympathetic fibers as well as visceral afferents

51
Q

What types of fibers are found in pelvic splanchnics

A

Visceral afferent fibers, preganglionic parasympathetics

52
Q

How are pelvic plexuses formed

A

By the merging of pelvic splanchnic nerves and inferior hypogastric plexuses

53
Q

Ascending parasympathetic fibers

A

arise from pelvic plexuses and ascend out of the pelvic inlet to reach sigmoid and descending colon

54
Q

Sacral sympathetic trunk is a continuation of what?

A

The lumbar sympathetic trunk

55
Q

Functions of sympathetic nerves in the pelvis

A

Vasoconstriction, inhibition of peristalsis, constriction of involuntary sphincters, ejaculation, remission of genital erection

56
Q

Functions of parasympathetic nerves in the pelvis

A

increase of peristalsis, stimulates contraction of detrusor in bladder, inhibits constriction of involuntary sphincters ,erection

57
Q

visceral reflex afferents

A

Travel retrograde with parasympathetics to the dorsal root ganglia

58
Q

Pelvic pain line

A

Corresponds to the lower limit of the peritoneum

59
Q

Pain fibers from intraperitoneal viscera or areas of organs covered in peritoneum follow?

A

Sympathetic system retrograde to T11-L1

60
Q

Pain fibers from the sub peritoneal viscera follow?

A

Parasympathetic fibers retrograde to dorsal root ganglia of S2,3,4

61
Q

Where does the pain line cross?

A

The middle of the sigmoid colon

62
Q

Have you gone over the pathways of sympathetics and parasympathetics for viscera of pelvis

A

Probably should do it more

63
Q

Have you reviewed the spinal anesthesia for childbirth?

A

Probably should look at it again
