• Radial Nerve

• Ulnar Nerve

• Median Nerve

The arcade of Frohse may compress the:

• Ulnar Nerve

• Anterior Interosseous Nerve

• Posterior Interosseous Nerve

• Musculocutaneous Nerve

Responsible for shoulder retraction

• Trapezius and Rhomboids

• Trapezius and Levator Scapulae

• Trapezius and Latissimus Dorsi

• Trapezius and Serratus Anterior

Triceps activity is enhanced by:

• Elbow extension combined with shoulder extension

• Elbow flexion combined with shoulder flexion

• Elbow flexion combined with shoulder extension

• Elbow extension combined with shoulder flexion

A forearm muscle that belongs to the extensor group but flexes the elbow is:

• Anconeous

• Brachioradialis

• Biceps Brachii

• Supinator

The radial head is kept in place by the:

• Biceps insertion

• Ulnar Collateral Ligament

• Trapezius

The center of gravity of the extended upper extremity is approximately:

• At the elbow

• Just above the elbow joint

• Just below the elbow joint

• At the midhumerus

Ulnar deviation at wrist is brought about by the action of the:

• Extensor carpi ulnaris

• flexor carpi ulnaris with palmaris longus

• flexor carpi ulnaris
