Anatomy I: Test 6 - Elbow Flexors

Which elbow flexors originate off of the humerus and which elbow flexor originates off the scapula?

Brachialis & brachioradialis - Humerus Short & long head of Biceps brachii - scapula via the coracoid process and supraglenoid tubercle of the scapula.

One of the elbow flexors inserts near the wrist at the styloid process. Which elbow flexor?

Brachioradialis

Of the three, which is the strongest elbow flexor?

Brachialis

"Bicep Burnouts" require forearm supination. Which of the elbow flexors is responsible for this action?

Biceps Brachii

List the actions of the 3 main elbow flexors (biceps brachii, brachialis, brachioradialis). 1pt extra credit if you put the correect action in place for Coracobrachialis.

Biceps Brachii - Supination of forearm (both heads), Elbow Flexion (both heads), Flexion of the humerus (short head) Brachialis - Elbow Flexion Brachioradialis - Flexion of the elbow in neutral/mid position Coracobrachialis - Flexion & Adduction of the humerus

State on exercise that would target each elbow flexor.

Biceps Brachii: supinated grip curl Brachialis: Neutral grip curl Brachioradialis: Reverse grip (pronated) curl

If your client experiences pain near the shoulder joint during active shoulder flexion, which elbow flexor is possibly injured?

The long head of the Biceps Brachii (travels through the capsule of the shoulder)

True or False: Pull ups work the elbow flexors.

True

Which elbow flexor inserts on the a) tuberosity of the ulna & b) tuberosity of the radius?

a) Brachialis b) Biceps Barachii via Bicep Aponeurosis

Are reverse curls (pronated grip) a better exercise for the biceps brachii or the brachioradialis?

brachioradialis
