Definition
Runs from anterior superior Iliac crest to the medial proximal tibia

band that runs diagonally and superficially
Term
Inguinal Ligamnet
Definition
Strong ligament that goes from iliac crest medially

Divides External Iliac vessels from femoral
Term
External Iliac Artery and Vein
Definition
Blood supply for lower limb

Become femoral artery and vein after passing beneath the inguinal ligament
Term
Femoral Artery, Nerve, and Vein
Definition
Located in femoral triangle

Very large, then branch

Dive deep through the adductor hiatus of the adductor magnus

Most superficial

Attaches to the iliac crest and the iliotibial tract
Term

Innervate and supply the gluteus maximus

Emerge inferior to piriformis and attach to underside of gluteus maximus
Term
Sciatic Nerve
Definition
Large nerve on posterior side of gluteal and thigh
Term
Gluteus Medius
Definition
Superior and deep to gluteus maximus
Term
Gluteus Minimus
Definition
deep to gluteus maximus and medius

Separated from medius by superior gluteal nerve, artery, and vein
Term

Runs from ischial tuberosity to intertrochanteric fossa of the femur
Term
Sacrotuberous Ligament
Definition
Large ligament running from sacrum to ischial tuberosity
Term
Sacrospinous Ligament
Definition
Smaller ligament runs from sacrum to spinous process of the ischium
