Vascular and Neural Elements of the Lower Limb Flashcards
where do arteries of the gluteal region arise from
internal iliac arteries
internal pudendal artery
lies anterior to the inferior gluteal artery
runs w/ pudendal nerve
entering the gluteal region through the greater sciatic foramen
enters the perineum through the lesser sciatic foramen
gluteal veins
tributaries of the internal iliac veins
accompany the corresponding arteries through greater sciatic foramen
what are the gluteal veins
superior gluteal
inferior gluteal
internal pudendal
nerves in the gluteal region
clunical
nerves from the sacral plexus
clunical nerve
superior
middle
inferior
sensory to skin over the buttocks
nerves from sacral plexus
sciatic
superior gluteal
inferior gluteal
nerve to obturator internus
nerve to quadratus femoris
posterior femoral cutaneous
pudendal
sciatic nerve
sacral plexus L4,S3
inferior to piriformis
supplies all muscles of the posterior compartment of the thigh
superior gluteal nerve
superior to piriformis
supplies all muscles of the posterior compartment of thigh
inferior gluteal nerve
inferior to piriformis
supplies gluteus maximus
nerve to obturator internus
innervates superior gemellus
nerve to quadratus femoris
innervates the hip joint and inferior gemellus
posterior femoral cutaneous nerve
sensory to inferior buttock
pudendal nerve
principle nerve of the perineum
doesn’t innervate anything in the gluteal region
travel over sacrospinous ligament to enter the lesser sciatic foramen to get to the perineum
how does the pudendal nerve travel
a group
-pudendal N
-internal pudendal artery and vein
-nerve to obturator internus
