Bone
These four joints contribute to shoulder motion.
What are the sternoclavicular, acromioclavicular, scapulothoracic, and glenohumeral joints?
These are the planes of movement that the arm moves in.
What are sagittal, frontal/coronal, and transverse?
These muscles make up the rotator cuff.
What are supraspinatus, infraspinatus, teres minor, and subscapularis?
These are the big 5 peripheral nerves of the brachial plexus.
What are musculocutaneous, axillary, radial, median, and ulnar?
This is the attachment of the UE to the axial skeleton.
What is the sternoclavicular joint?
This is the most common mechanism of acute injury to the upper extremity.
What is a FOOSH?
This muscle holds down the scapula to the rib cage and is innervated by this nerve.
What is the serratus anterior, innervated by the long thoracic nerve?
This anatomical structure deepens the glenoid fossa, allowing for more passive stability of the humeral head on the scapula.
What is the glenoid labrum?
This bony landmark will restrict full shoulder abduction if not cleared from the acromion through external rotation.
What is the greater tubercle of the humerus?
These two muscles work together to upwardly rotate the scapula during upward rotation, forming a powerful force couple.
What are trapezius and serratus anterior?
These muscles are tight in upper crossed syndrome.
What are upper trapezius, levator scapulae, pectoralis major, pectoralis minor, upper cervical extensors, SCM, scalenes, and teres major/minor?
Adhesive capsulitis (frozen shoulder) is characterized by a global restriction of both active and passive ranges of motion. True or false?
What is true?
