What is the cubital fossa? |
|
Definition
The cubital fossa is the depression on the anterior aspect of the elbow |

Definition
|
|
Term
What are the relative positions of these structures in the cubital fossa (Biceps brachii tendon, brachial artery, median nerve) |
|
Definition
Biceps brachii tendon is lateral Brachial artery is intermediate Median nerve is medial |
|
