Flashcards in Anatomy Lecture 1 Pelvis Deck (43)
Which bones form the bony pelvis?
What is the innominate bone? How many do we have?
ilium, ischium, pubis
What are the beginning and end points of the iliac crest?
ASIS to PSIS
The ischium and pubis together form what bony feature of the pelvis?
Can you palpate the ischial tuberosities?
From a seated position, what part of the bony pelvis are you sitting on?
What bony feature of the pelvis is directly lateral to the pubic symphesis?
Which sex is the pubic arch thicker in?
What foramen lies between the ischiopubic ramus and the superior pubic ramus?
Name the 3 joints of the pelvis
What type of joint is the hip joint?
What type of joint is the pubic symphysis?
What are the attachments of the inguinal ligaments?
ASIS to pubic tubercle
What bony features of the ilium are palpatable?
ASIS, iliac crest, PSIS
Can you palpate the ischial spines?
Only on vaginal examination (a finger breadth into the vagina at the 4 and 8 o'clock positions)
What is the clinical relevance of palpating the ischial spines?
Locating approximate position of femoral nerve for femoral nerve block during labour
What are the most important ligaments of the pelvis and what are their attachments?
sacrospinous: sacrum to iliac spine
sacrotuberous: sacrum to ischial tuberosity
Describe the course of the pudendal nerve through the pelvis
Across iliac fossa
Out greater sciatic foramen
Directly back in lesser sciatic foramen
THIS IS NOT COMPLETE - FINISH
When do the sacrotuberous and sacrospinous ligaments relax?
During late pregnancy
What structures contribute to the pelvic inlet?
Superior pubic ramus
What structures contribute to the pelvic outlet?
The pelvic cavity is continuous with the _____
The pelvic cavity lies between the ____ and ____
pelvic inlet and plelvic floor
What structure forms the pelvic floor?
Levator ani muscle?
What nerve supplies the levator ani and what SC roots is it formed from?
Pudendal nerve (double check) S2, 3, 4 keep your guts off the floor
What feature of the pubis is wider in a female compared to a male
Subpubic angle and pubic arch
Is the pelvic cavity shallower in the female or male?
Are the AP and transverse diameters of the pelvic inlet wider in a male or female?
