Neurovascular Structures of the Anterior Forearm Flashcards
What is the main nerve of the anterior compartment of the forearm?
The median nerve
Where does the median nerve lie in relation to the brachial artery within the cubital fossa?
Initially, the nerve lies lateral to the artery but it crosses over halfway through its descent and becomes medial to the artery
Which muscles in the forearm do the median nerve not supply?
Flexor carpi ulnaris
Medial half of flexor digitorum profundus
How does the median nerve enter the hand?
By passing below the flexor retinaculum
What is the course of the ulnar nerve in the forearm?
After passing posterior to the medial epicondyle of the humerus the ulnar nerve enters the forearm by passing between the heads of flexor carpi ulnaris
Where does the ulnar nerve lie in relation the the ulnar artery at the distal part of the forearm?
The nerve lies anterior to the artery
Why is the ulnar artery pulse non-palpable?
It passes under the flexor retinaculum
What are the terminal branches of the brachial artery?
Radial artery
Ulnar artery
Where does the brachial artery divide into two terminal branches?
At the neck of the radius
