Arm and Forearm Flashcards
What are the three branches of the Brachial Artery
Deep brachial (profunda brachi) Artery
Superior Ulnar Collateral Artery
Inferior Ulnar Collateral Artery (around the elbow)
NOTE: not the main divisions which are the ulnar and the radial arteries
Where the the Biceps brachii attach?
Radial tuberosity
Where does the brachialis attach?
Ulnar tuberosity
Visualize the coronoid fossa. Where does it sit. What inserts there?
Sits on the anterior side of the humerus and the coronoid of the ulna bone attaches there on the anterior side.
Visualize the olecronon fossa. Where does it sit. What inserts there?
Sits on the posterior side of the humerus. The olecronon of the ulna bone attaches to it.
Visualize the radial fossa. Where does it sit. What inserts there?
On the anterior side of the humerus. The radial bone attaches there.
What ligament insures the biceps ligament is maintained within the intertubercular groove?
transverse humeral ligament.
Where does the brachial artery lie?
The brachial artery runs above the long head of the triceps, corcobrachialis and brachialis, but below the biceps brachii.
What nerve does the main brachial artery run with?
The median nerve under the biceps brachi
What nerve does the deep brachial artery run with?
The radial nerve in the radial groove which is betwen the lateral head and the middle head of the triceps.
Which tricep is considered the work horse
The medial head
What three muscles attach to or originate from the corocoid process
Pectoralis minor
Short head of biceps
Corocobrachialis
What does recurrent mean?
Bloodflow is flowing backwards
What does the Musculocutaneous nerve become?
The lateral antebrachial cutaneous nerve
If you loose the musculocutaneous nerve will you get complete loss of flexion?
No because we still have the flexors of the forearm. this is the opposite to what would happen if the radial nerve was damaged because the radial nerve innervates all extensors.
