Shoulder and Scapula
This structure originates above the spine of the scapula and passes through the subacromial space.
What is the supraspinatus?
This nerve, branching off C5-C7, has the ability to become compressed between the anterior and middle scalenes, leading to potential winging of the scapula.
What is the long thoracic nerve?
A sternocostal joint is made of these structures.
What are the sternum and costal cartilage?
This muscle(s) are the primary flexor(s) of the elbow.
What are the biceps brachii, brachialis, and brachioradialis?
This artery is the main blood supply to the upper limb and is a continuation of the subclavian artery.
What is the axillary artery?
These structures are the primary lateral rotator(s) of the arm.
What are the infraspinatus and teres minor?
This large nerve arises from the posterior cord and supplies all the extensor muscles of the arm and forearm.
What is the radial nerve?
The primary articulation site of the humerus and radius occurs at this structure.
What is the capitulum?
This muscle of the volar forearm is an exception to the rule, as it is innervated by the ulnar nerve instead of the median nerve.
What is the flexor carpi ulnaris?
This major branch of the brachial artery supplies the deep structures of the arm.
What is the profunda brachii artery?
The lower fibers of the trapezius have the ability to perform these motion(s).
What are scapular depression and upward rotation?
This nerve, running behind the medial epicondyle, is commonly injured when hitting the 'funny bone'.
What is the ulnar nerve?
These joint(s) comprise the shoulder complex
What are the GH, AC, SC, and ST joints?
These are the muscle that have an attachment to the medial epicondyle of the humerus.
What are the Pronator Teres, FCU, Palmaris Longus, FCU, and FDS?
The lumen of an artery is composed of this type of muscle and collagen
What are smooth muscle and type III collagen?
A patient has difficulty performing GH abduction due to compression of this nerve running through this space.
What is the axillary nerve and the quadrangular space?
The median nerve is most likely to become irritated at this location in the elbow/forearm.
Where is between the heads of the pronator teres?
Pronation and supination occur at this joint(s).
What is the superior and inferior radioulnar joints?
The deep branch of the median nerve innervates these forearm muscles.
What are the FPL, FDP to fingers 2 and 3, Pronator Quadratus?
The sympathetic nervous system has this effect on an artery.
What is vasodilation?
This muscle is in the best position to prevent the head of the humerus from subluxing anteriorly due to its location on the humerus
What is the subscapularis?
Damage to the posterior cord of the brachial plexus may affect these nerves.
What are supper, middle, and lower subscapular nerves, the radial nerve, and the axillary nerve?
These ligaments support the glenohumeral joint.
What are the superior, middle, and inferior GH ligaments, coracohumeral ligament
These are the common attachments of the deltoid and trapezius muscles.
What are the spine of the scapula, acromion, and lateral clavicle?
This body system proportionally requires the most amount of oxygen that is carried in the arterial system.
What is the nervous system?
