Savarese Ch 7: Upper Extremities Flashcards
Name to muscles of the rotator cuff:
A trigger point
S: supraspinatus
I: Infraspinatus
T: Teres minor
S: Subscapularis
What is the action of supraspinatus
ABduction of the arm
What is the action of infraspinatus
External rotation of arm
What is the action of the Teres minor
External rotation of the arm
What is the action of the subscapularis
Internal rotation of the arm
What is the primary flexor of the shoulder?
Deltoid (anterior portion)
What is the primary ABductor of the shoulder?
Deltoid (middle portion)
What are the primary extensors of the shoulder?
Latissimus dorsi
Teres Major
Deltoid (Posterior portion)
What are the primary ADductors of the shoulder
Pectoralis Major
Latissimus dorsi
What are the primary external rotators of the shoulder
Infraspinatus
Teres Minor
What is the primary internal rotator of the shoulder
Subscapularis
Explain why the path of the subclavian artery is clinically significant
It passes between the anterior and middle scalenes.
Contracture of these may compromise arterial supply to the arm. (venous drainage not affected b/c the subclavian vein passes anterior to the anterior scalene)
Subclavian artery –> _____ at the _______
Subclavian artery –> Axiallary artery at the lateral border of the first rib
Axillary artery –> _____ at the _______
Axillary artery –> Brachial artery at the inferior border of the teres minor
What is the first major branch of the brachial artery? Where does it course?
Profunda brachial artery
Accompanies the radial nerve in its posterior course of the radial groove.
Brachial artery –> ____________ at _____
Brachial artery –> ulnar & radial arteries under the bicipital aponeurosis
Radial artery: supplies ____; Forms ____
Supplies: elbow, wrist, dorsal aspect of the hand
Forms: most of the DEEP palmar arterial arch
Ulnar artery: Supplies ____; Forms ____
Supplies: elbow, wrist, dorsal aspect of the hand
Forms: Most of the SUPERFICIAL palmar arterial arch
What supplyes the nerves to the Upper extremity (UE)?
The brachial plexus
What composes the brachial plexus (general)? (5)
C5-T1 ROOTS exit the spinal cord and form --> TRUNKS --> DIVISIONS --> CORDS --> BRANCHES
Can you (still) draw the brachial plexus?

Which 2 tests/techniques are good screening examinations for gross range of motion of the shoulder?
- Apley’s Scratch test
2. Spencer Technique: for more accurately testing individual motions of the shoulder
What is the most common somatic dysfunction of the shoulder?
Restriction in internal and external rotation
