What type of artery is the common iliac artery?
The common iliac artery (CIA) is a short artery transporting blood from the aorta towards the pelvic region and lower extremity. Sometimes this paired artery is also referred to as its plural form common iliac arteries. The left and right common iliac arteries are the terminal branches of the abdominal aorta.

Where is the uterine artery?
Uterine artery. In females, the uterine artery courses within the base of the broad ligament, superior to the ureter before reaching the cervix. At the cervix, the uterine artery ascends along the lateral margin of the uterus to the uterine tube and forms an anastomosis with the ovarian artery. During pregnancy, the uterine artery enlarges significantly to supply blood to the uterus, ovaries, and vaginal walls. This artery is not present in males.
What is the superior gluteal artery?
Superior gluteal artery. The terminal branch of the posterior trunk. The superior gluteal artery courses between the lumbosacral trunk and the ventral ramus of the S1 spinal nerve. This artery supplies the gluteal region, with anasto-motic overlap with the inferior gluteal artery.
What is the internal iliac artery?
The internal iliac artery (formerly known as the hypogastric artery) is the main artery of the pelvis .
What is the arrangement of the internal iliac artery?
The exact arrangement of branches of the internal iliac artery is variable. Generally, the artery divides into an anterior division and a posterior division, with the posterior division giving rise to the superior gluteal, iliolumbar, and lateral sacral arteries. The rest usually arise from the anterior division.
What is the name of the ligament that extends from the pelvis to the umbilicus?
At birth, when the placental circulation ceases, the pelvic portion only of the umbilical artery remains patent gives rise to the superior vesical artery (or arteries) of the adult; the remainder of the vessel is converted into a solid fibrous cord, the medial umbilical ligament (otherwise known as the obliterated hypogastric artery) which extends from the pelvis to the umbilicus.
Which arteries are lateral sacral arteries?
the iliolumbar artery (from the posterior division of the internal iliac artery) with the last lumbar artery (from the aorta) the lateral sacral arteries (from the posterior division of the internal iliac artery) with the median sacral artery (from the aorta)
Which artery is carried on by the anastomoses of the middle rectal artery?
The circulation after ligature of the internal iliac artery is carried on by the anastomoses of: the middle rectal artery (from the anterior division of the internal iliac artery ) and the superior rectal artery (a branch of the inferior mesenteric artery)
Where is the iliac artery located?
The place of division of the internal iliac artery varies between the upper margin of the sacrum and the upper border of the greater sciatic foramen .
Which artery supplies the walls and viscera of the pelvis, buttock, and the reproductive organs?
The internal iliac artery supplies the walls and viscera of the pelvis, the buttock, the reproductive organs, and the medial compartment of the thigh. The vesicular branches of the internal iliac arteries supply the bladder
What branch of the iliac artery divides into anterior and posterior trunks?
Internal iliac artery branches. The internal iliac artery divides into anterior and posterior trunks at the level of the superior border of the greater sciatic foramen. Branches from the posterior trunk contribute to the supply of the lower posterior abdominal wall, the posterior pelvic wall, and the gluteal region.
Where do iliac arteries travel?
The common iliac arteries travel along the inner surface of the ilium, descending posterior to the cecum and sigmoid colon. At the level of the lumbosacral joint, each common iliac divides to form an internal iliac artery and an external iliac artery.
Why is the iliac artery aneurysm so thick?
Arteries have thick walls to withstand normal blood pressure. However, certain medical problems, genetic conditions, and trauma can damage or injure artery walls.
How does a surgeon insert a catheter into an aneurysm?
The surgeon first inserts a catheter into an artery in the groin (upper thigh) and threads it to the aneurysm. Then, using an x ray to see the artery, the surgeon threads the graft (also called a stent graft) into the aorta to the aneurysm.
What is the medial umbilical ligament?
The fibrous remnant of the umbilical artery itself is the medial umbilical ligament. The superior vesical artery normally originates from the root of the umbilical artery and courses medially and inferiorly to supply the superior aspect of the bladder and distal parts of the ureter.
What is the fibrous remnant of the umbilical artery?
The fibrous remnant of the umbilical artery itself is the medial umbilical ligament.
What is the first branch of the anterior trunk?
The first branch of the anterior trunk is the umbilical artery, which gives origin to the superior vesical artery and then travels forward just inferior to the margin of the pelvic inlet. Anteriorly, the vessel leaves the pelvic cavity and ascends on the internal aspect of the anterior abdominal wall to reach the umbilicus. In the fetus, the umbilical artery is large and carries blood from the fetus to the placenta. After birth, the vessel closes distally to the origin of the superior vesical artery and eventually becomes a solid fibrous cord. On the anterior abdominal wall, the cord raises a fold of peritoneum termed the medial umbilical fold. The fibrous remnant of the umbilical artery itself is the medial umbilical ligament.

What is the internal pudendal artery?

Which arteries are parietal?
The obturator, internal pudendal and inferior gluteal arteries are parietal branches, whereas the other arteries in the above list are visceral arteries (i.e. umbilical, superior and inferior vesical, vaginal, uterine and middle rectal artery).

Which artery exits the pelvis via the greater sciatic foramen?
superior gluteal artery. exits the pelvis via the greater sciatic foramen and here it is found posterior to the ilium and superior to piriformis muscle. inferior gluteal artery. posterior to the ischial spine, inferior to piriformis muscle; after exiting the pelvis it is covered by gluteus maximus muscle.
What is the division of the sciatic foramen?
At the superior margin of the greater sciatic foramen it divides into an anterior division and posterior division. The anterior division continues down to the ischial spine anterior to piriformis giving off visceral and parietal branches. The posterior division only gives rise to parietal branches.
