pelvis Flashcards
what bones make up the pelvis
Iliac crest ASIS PSIS Ischium Ilium Pubis Iliac fossa Pubic symphysis Sacrum Coccyx Acetabulum Pelvic inlet/ outlet SIJs Ischial spine Sacral foramina Obturator foramen
what vessels are in the pelvis
L and R common iliac arteries L and R external iliac arteries L and R iliac vein L and R femoral vein Sciatic nerve
course of the abdominal aorta/common iliacs
- The abdominal aorta descends into the pelvis anterior to the lumbar vertebra slightly to the left of the midline
- The descending aorta bifurcates into the left and right common iliac arteries
- Each common iliac artery bifurcates at the upper margin of the SIJ into the internal and external iliac arteries
course of the internal iliac artery
extends posteromedially into the pelvis just medial to the external iliac vein and branches into an anterior trunk and a posterior trunk
course of the external iliac artery
extends along the pelvic brim to exit the iliac fossa and course under the inguinal ligament to supply the leg
It then then becomes the femoral artery at approx. The level of the ASIS
course of the internal iliac veins
- Ascends the pelvis medial to the internal iliac artery as it returns blood from the pelvic viscera
- Tributaries of the internal iliac vein are similar to that of the branches of the internal iliac artery with some differences, such as the iliolumbar vein, which usually drains into the common iliac vein
course of the femoral veins
- The popliteal vein becomes the femoral vein in the thigh, which courses medial to the femoral artery and continues deep to the inguinal ligament as the external iliac vein
course of the common iliac vein
The common iliac vein arises posterior to the common iliac artery from the junction of the internal and external iliac veins
course of the sciatic nerve
exits the pelvis through the greater sciatic foramen and continues to descend vertically along the posterior thigh
- Its branches supply the posterior compartment of the thigh and all compartments of the distal leg and foot
- Runs deep to the gluteus maximus muscle and descends in the midline of the thigh, where it usually divides into two terminal branches: the tibial and common peroneal (common fibular) nerves
organs within the pelvis
Bladder Ureter Sigmoid colon Rectum/anus Descending colon
anatomy of the male pelvis
Vas deferens Spermatic cord Seminal cord Ejaculatory duct Urethra Testis Epididymis Scrotum Penis - Corpus cavernosum - Spongiosum Prostate
anatomy of the female pelvis
Ovary Fallopian tube (uterine tube) Uterus - Body - Fundus - Endometrium - Myometrium Cervix Vagina
