Upper Limb 2 Station 2 & 3 - Neurovascular Structures of the Anterior Arm and Cubital Fossa Anatomy Flashcards
When does the axillary artery turn into the brachial and when does the brachial end and become the radial and ulnar
Lower border of teres major
Ends in the cubital fossa
What is one of the main deep artery branches given off by the brachial artery?
Profunda brachii
Best place to compress the brachial artery in the case of a haemorrhage?
Middle of the arm
Median nerve arises in the BLANK by what two roots?
In the axilla from the brachial plexus
Lateral and medial cords
Median nerve descends alongside the BLANK side of the axillary artery and the BLANK part of the brachial artery.
Lateral side of the axillary artery
Upper part of brachial artery
What does the median nerve supply in the arm?
Flexor muscles in anterior compartment of forearm besides the two supplied by ulnar nerve
Ulnar nerve arises from what cord of the brachial plexus
Medial cord
Describe the path of the ulnar nerve.
Runs medial side of brachial artery
Enters the posterior compartment of the arm through the medial intermuscular septum (which is slightly higher than the elbow)
Runs alongside medial head of triceps and to the back of the medial epicondyle
What does the ulnar nerve innervate?
Flexor carpi ulnaris
Flexor digitorum profundus (medial half)
And muscles of the hand
Where/what is the cubital fossa?
Triangular depression in front of elbow
Injury to radial groove could damage what nerve?
Radial nerve
Injury to medial epicondyle could damage what nerve?
Ulnar nerve
Injury to surgical neck could damage what nerve?
Axillary nerve

Medial border is…
Lateral border is…
Imaginary line drawn between medial and lateral epicondyles
Pronator teres muscle
Brachioradialis muscle
Cubital fossa contains what structures?
