Where is trochanteric anastomosis found?
head of the femur
The trochanteric anastomosis provides circulation around the head of the femur. It includes the superior gluteal artery and the medial and lateral circumflex femoral arteries (the former of which provides the main supply to the femur).
What is trochanteric and cruciate anastomosis?
The cruciate anastomosis is an arterial network located on the posterior surface of the proximal femur. Some authors refer to it as the collateral circulation at the hip joint. The cruciate anastomosis is formed by the: First perforating branch of deep femoral artery.
What is the genicular anastomosis?
[TA] a periarticular arterial network over the front and sides of the knee, formed by branches of the descending genicular artery, of the five genicular arteries from the popliteal, of the anterior tibial recurrent, and of the fibular circumflex branches of the posterior tibial.
What is the purpose of the cruciate anastomosis?
The cruciate anastomosis allows blood to reach the popliteal artery indirectly from the internal iliac artery and IGA if there is an interruption of flow between the external iliac and the femoral arteries.
Where is the superior gluteal artery?
pelvis
The superior gluteal artery is an artery of the pelvis. It arises directly from the posterior trunk of the internal iliac artery as its largest branch. Along its course, it supplies muscles of the posterior pelvic region. The superior gluteal artery gives off two terminal branches; superficial and deep.
What are the anastomosis of the lower limb?
Pelvic and gluteal anastomoses The divisions of the common iliac arteries are responsible for delivering oxygenated blood to the lower extremity. The common iliac artery bifurcates to form the external and internal iliac arteries about half way between the first and second anterior sacral foramina.
What forms the cruciate anastomosis?
Its four components are: Inferior gluteal artery. Transverse branches of the lateral circumflex femoral artery and the medial circumflex femoral artery. Ascending branch of the first perforating artery from the profunda femoris.
What is anastomosis around knee joint?
The patellar network (circulatory anastomosis around the knee-joint, patellar anastomosis, genicular anastomosis, articular vascular network of knee or rete articulare genus) is an intricate network of blood vessels around and above the patella, and on the contiguous ends of the femur and tibia, forming a superficial …
What is attached to the greater trochanter?
The greater trochanter is the attachment site for five muscles: the gluteus medius, gluteus minimus, piriformis, obturator externus, and obturator internus.
Where is the greater trochanter located?
The greater trochanter is located at the top of the thighbone (femur) and is the most prominent and widest part of the hip.
Where do superior and inferior gluteal arteries come from?
Inferior gluteal artery
| Origin | Internal iliac artery |
|---|---|
| Supply | Piriformis, ischiococcygeus, iliococcygeus, gluteus maximus, obturator internus, superior and inferior gemelli, quadratus femoris muscles; sciatic nerve, skin of gluteal and thigh regions |
Where does inferior gluteal artery come from?
Origin. The inferior gluteal artery originates as a branch of the anterior division of the internal iliac artery. It approaches the greater sciatic foramen by passing back through the parietal pelvic fascia and between the S1 – S2, or S2 – S3 nerve roots.
What does cruciate mean?
/ˈkruː.ʃi.ət/ used to refer to any body structure that forms the shape of a cross, especially the ligaments of the knee: Reconstruction of the anterior cruciate ligament is a common procedure.
