|
Term
|
Definition

|
|
Term
| age 12-14 when the ossification of the femur has extended into the pit |
|
Definition
| when does the anastamoses between the head of the femur and the branches of the profunda occur? |
|
|
Term
| if the retinacular arteries are torn during a fracture of the neck, there may be aseptic vascular necrosis |
|
Definition
| why is it bad if your retinaculr arteries don't anastamose with the profunda femoris arteries? |
|
|
Term

|
Term
|
Definition

Definition
| muscle border that is key to naming stuff in the gluteal region |
|
|
Term
| through greater sciatic foramen superior to piriformis |
|
Definition

|
|
Term
| through greater sciatic foramen inferior to piriformis |
|
Definition

|
|
Term
| passes through greater sciatic foramen inferior to piriformis (80-90% of the time sometimes splits) |
|
Definition
| where does the sciatic nerve pass in relation to the piriformis (most of the time) |
|
|
Term
| pudendal nerve/internal pudendal AV pass through the greater sciatic foramen inferior to piriformis then into the pelvis through the lesser sciatic foramen (the nerve goes out around the pelvic diaphragm then back in with the vessels) |
|
Definition
| where does the pudendal nerve pass in relation to the piriformis? |
|
|
Term
| peroneum between the legs (its a branch of the lumbosacral plexus) |
|
Definition
