Q: [...]: four muscles that hold the humeral head in the glenoid fossa, stabilizing the glenohumeral joint.
A: Rotator cuff
Muscles of the rotator cuff:
1. Supraspinatus
2. Infraspinatus
3. Teres minor
4. Subscapularis
Q: Main action of the supraspinatus: [...]
A: Abduction
Q: Main action of the infraspinatus: [...] rotation
A: External
Q: Main action of the teres minor: [...] rotation
A: External
Q: Main action of the subscapularis: [...] rotation
A: Internal
Comment 3: A-E-E-I the SITS muscles allow you to point towards the sky
Topic: Upper Extremities
Bone Wizardry Lock: SITS muscles (Supraspinatus, Infraspinatus, Teres minor, Subscapularis) each do one thing: abduct, externally rotate, externally rotate, internally rotate. Losing any one shifts glenohumeral mechanics enough to cause impingement.

Q: The deltoid is the main shoulder [...] after the first 15 degrees; the anterior deltoid assists with shoulder [...].
A: abductor; flexion
Q: [...] controls shoulder abduction after supraspinatus initiates the first 15 degrees; its anterior fibers assist flexion.
A: Deltoid
Q: The primary adductors of the shoulder are the [...] and [...].
A: pec major; latissimus dorsi
Q: The primary [...] of the shoulder are the pec major and latissimus dorsi.
A: adductors
Q: The primary external rotators of the shoulder are the [...] and [...].
A: infraspinatus; teres minor
Q: The primary [...] of the shoulder are the infraspinatus and teres minor.
A: external rotators
Topic: Upper Extremities
Bone Wizardry Lock: Supraspinatus gets abduction started (0-15 degrees); deltoid carries it the rest of the way. Pec major and lat pull it back down. Infraspinatus and teres minor keep the humeral head from spinning forward.

Q: The subclavian artery passes between the [...] scalenes.
A: anterior and middle
Q: The subclavian vein passes anterior to the [...] scalene.
A: anterior
Comment: Therefore, contracture of the anterior and middle scalenes may compromise arterial supply to the arm, but does not affect venous drainage.
Topic: Upper Extremities
Bone Wizardry Lock: The artery runs between the anterior and middle scalenes; the vein runs anterior to the anterior scalene. Tight scalenes cut off arterial flow first, which is exactly what thoracic outlet syndrome does.

Q: The subclavian artery becomes the [...] artery at the lateral border of the first rib.
A: axillary
Q: The subclavian artery becomes the axillary artery at the lateral border of the [...] rib.
A: first
Q: The axillary artery becomes the [...] at the inferior border of the teres major muscle.
A: brachial artery
Q: The axillary artery becomes the brachial artery at the inferior border of the [...] muscle.
A: teres major
Q: The [...] artery is the first major branch of the brachial artery.
A: profunda brachii
Q: The [...] artery accompanies the radial nerve in its posterior course of the radial groove.
A: profunda brachii
Q: The brachial artery divides into the [...] and [...] arteries under the bicipital aponeurosis.
A: ulnar; radial
Q: The radial artery courses the lateral aspect of the forearm supplying blood to the elbow, wrist, dorsal aspect of the hand, and eventually forming most of the [...].
A: deep palmar arterial arch
Q: The radial artery courses the [...] aspect of the forearm supplying blood to the elbow, wrist, dorsal aspect of the hand, and eventually forming most of the deep palmar arterial arch.
A: lateral
Topic: Upper Extremities
Bone Wizardry Lock: Follow the name changes: subclavian to axillary at rib 1, axillary to brachial at teres major, brachial splits into radial and ulnar under the bicipital aponeurosis. Radial runs lateral and feeds the deep palmar arch; ulnar runs medial and feeds the superficial palmar arch.

Q: The ulnar artery courses the medial aspect of the forearm supplying blood to the elbow, wrist, dorsal aspect of the hand and eventually forming most of the [...]
A: superficial palmar arterial arch.
Q: The ulnar artery courses the [...] aspect of the forearm supplying blood to the elbow, wrist, dorsal aspect of the hand and eventually forming most of the superficial palmar arterial arch.
A: medial
Topic: Upper Extremities
Bone Wizardry Lock: Ulnar artery runs medial, forms most of the superficial palmar arch. Radial runs lateral, forms most of the deep arch. Superficial = ulnar-dominant. If you blank on the boards: ulnar = superficial.
