#1: Anatomy Flashcards
Function of the pudendal nerve: (3)
1- sensory innervation to the external genitalia
2- innervates the striatal urethra and anal sphincters
3- innervates deep and superficial perineal structures
Where pudendal nerve block administered
ischial spine
main arterial supply of the perineum and lower 1/3rd of the vagina
Internal pudendal artery
artery that supplies upper 2/3rds of the vagina
Vaginal artery
main arterial supply of the uterus
Uterine artery
main supply to the ovary
Ovarian artery
Right ovarian vein returns to the:
IVC
Left ovarian vein returns to the:
Left renal vein
Drainage of the ovaries:
travels with the ovarian vessels to the para-aortic lymph nodes
Drainage of the uterus and the upper two-thirds of the vagina:
flows through the obturator and internal and external iliac lymph nodes, ultimately draining into the common iliac nodes
Drainage of distal one-third of the vagina, urethra, and vulva:
drains to the inguinal lymph nodes
Two synovial joints of the bony pelvis:
sacroiliac joints and lumbosacral joints
–unflexible
Two cartilaginous joints of the bony pelvis:
sacrococcygeal and symphysis pubis joint
–flexible and react to relaxin
pelvimetry is used to assess for
cephalopelvic disproportion
heavy or prolonged flow
menorrhagia
development of breasts
