Blood vessels of gluteal region Flashcards
What are the blood vessels that supply blood to the gluteal region?
Superior gluteal
inferior gluteal
obturator
Where does the deep branch of the superior gluteal run?
lies between the gluteus medius muscle and the hip bone
What does the deep branch of the superior gluteal divide into?
superior and inferior divisions
What is the path of the superior branch of the deep superior gluteal?
runs along the upper border of gluteus minimus as far as the anterior superior iliac spine.
What is the path of the inferior branch of the deep superior gluteal artery?
crosses gluteus minimus to supply it, the gluteus medius muscle and the hip joint. It also contributes to the anastomosis around the hip joint by joining with the:
Lateral circumflex femoral artery.
Inferior gluteal artery.
Ascending branch of the medial circumflex artery.
What does the superior branch of the deep superior gluteal branch anastomose with?
It contributes to the anastomosis around the hip joint by joining with the:
Deep circumflex iliac artery.
Ascending branch of the lateral circumflex femoral artery
What does the inferior branch of the deep superior gluteal artery anastomose with?
It also contributes to the anastomosis around the hip joint by joining with the:
Lateral circumflex femoral artery.
Inferior gluteal artery.
Ascending branch of the medial circumflex artery.
What is the path of the inferior gluteal artery?
runs backwards and laterally between the first and second, or second and third, ventral sacral nerves. It traverses the greater sciatic foramen below the piriformis and enters the gluteal region.
to what muscles does the inferior gluteal artery provide branches to inside the pelvis?
piriformis, coccygeus levator ani muscles, perirectal fat, the fundus of the bladder, the seminal vesicles the prostate
to what muscles does the inferior gluteal artery provide branches to outside the pelvis?
gluteus maximus, obturator internus, the gemelli, quadratus femoris the upper hamstrings
Where does the artery to the sciatic nerve run?
on its surface and may accompany it as far as the upper thigh
Where may the inferior gluteal and internal pudendal arise?
a common stem from the internal iliac artery
What is the cruciate anastomoses?
involves inferior gluteal artery (superiorly), lateral
medial femoral circumflex arteries (mediolaterally),
the first perforating branch of the profunda femoris artery (inferiorly)
What are the bursae of the hip?
Ischial
trochanter
Gluteo femoral
What does the ischial bursae separate?
gluteus maximus from ischial tuberosity
