anatomy Flashcards
where do the majority of the arteries of the pelvis and perineum arise
internal iliac artery
except gonadal artery and superior rectal artery
anastomosis of the female pelvis
between the uterine artery and the ovarian artery
uterine artery and vaginal artery
where does most of the veins in the pelvis drain
internal iliac vein
some drains into superior rectal > hepatic
some drain via lateral sacral veins > internal vertebral venous plexus
where does lymph of the superior pelvic viscera drain
external iliac nodes
common iliac, aortic, thoracic duct, venous system
where pelvic viscera
deep perineum
internal iliac nodes
common iliac, aortic, thoracic duct, venous system
where does the inguinal ligament attach
between the asis and the pubic tubercle
where does the sacrospinous ligament attach
sacrum and ischial spine
where does the sacrotuberous ligament attach
sacrum and ischial tuberosity
what is moulding
the movement of one bone over another to allow the foetal head to pass through the pelvis during labour
what is the vertex
the area of the foetal skull outline by the anterior and posterior fontanelles and the parietal eminences
what position should the foetal head be at the pelvic inlet
transverse
what position should the foetal head be in the pelvic cavity
should rotate and should be flexed
what position should the foetal head be at the pelvic outlet
ideally occipitoanterior and extension of the head
nerve control of uterine cramping
hormonal (sympathetic/parasympathetic)
nerve control of uterine contraction
hormonal (sympathetic/parasympathetic)
