Term
| What is the superior transverse scapular ligament? |
|
Definition
| The ligament that goes over the suprascapular notch and makes it into a foramen |
|
|
Term
| What goes through the suprascapular foramen? |
|
Definition
| Suprascapular Nerve, sometimes the suprascapular artery and vein |
|
|
Term
| Why does the suprascapular artery and vein typically not go through the suprascapular foramen? |
|
Definition
| Since arteries and veins have a lumen they tend to grow away from enclosed spaces such as a foramen |
