QuestionAnswer
Where does the glenohumeral joint articulate? head of the humerus with the glenoid cavity of the scapula
movements of the shoulder joint - flexion/extension - abduction/adduction - medial/lateral rotation
Where does the scapula attach to the axial skeleton? acromioclavicular joint
movements of the scapula - upward/downward rotationa - retraction/protraction - elevation/depression
What muscle structure do these muscles make up.. - rhomboids - levator scapulae - trapezius - serratus anterior - pec minor scapular sling
Where do all muscles of the scapular sling insert? scapula and clavicle
Where do all muscles of the scapular sling originate? vertebral column and rib cage
What is a common action/function of the muscles of the scapular sling? anchor the scapula to the axial skeleton, stabilizing the upper limb
What muscle structure do these muscles make up.. - supraspinatus - infraspinatus - teres minor - subscapularis rotator cuff
Where do 3 of the 4 rotator cuff muscles attach? greater tubercle of the humerus
What is a common action/function of the muscles of the rotator cuff? rotate the humerus
The deltoid is the only muscle of what muscle structure? shoulder cap
What group do these muscles make up.. - pec major - teres major - latissimus dorsi intertubercular groove
What muscles make up the anterior compartment of the brachial muscles? - brachialis - coracobrachialis - biceps brachii
What is a common action/function of the anterior compartment of the brachial muscles? elbow and shoulder flexion
strong, triangle shaped ligament that spans the medial side of the elbow joint ulnar collateral ligament
What are the actions/functions of the ulnar collateral ligament? - stabilizes medial side of elbow joint - prevents lateral flexion and medial translation of the elbow joint - stabilizes the elbow during flexion
attaches to the lateral epicondyle of the humerus near its bottom margin and radiates as a fan-shaped ligament across the lateral surface of the elbow joint radial collateral ligament
What are the actions/functions of the radial collateral ligament? - stabilizes the lateral side of elbow joint - prevents medial flexion and lateral translation of the elbow joint - stabilizes the elbow during flexion
a thick, ring-like band that surrounds the head of the radius and anchors it into the radial notch of the ulna annular ligament
What are the actions/functions of the annular ligament? anchors and stabilizes the proximal radio-ulnar joint
What muscles make up the deep group of the anterior antebrachial muscles? - flexor digitorum profundus - flexor pollicis longus - pronator quadratus
What muscles make up the superficial group of the anterior antebrachial muscles? - pronator teres - flexor carpi radialis - palmaris longus - flexor carpi ulnaris - flexor digitorum superficialis
Where do 5 of the 8 muscles of the superficial group of the anterior antebrachial muscles attach? medial epicondyle of the humerus
What are the actions/function of the superficial group of the anterior antebrachial muscles? wrist and finger flexion
What muscles make up the lateral group of the posterior antebrachial muscles? - brachioradialis - extensor carpi radialis longus/brevis - extensor digitorum - extensor digiti minimi - extensor carpi ulnaris - supinator - anconeous
What muscles make up the radial group of the posterior antebrachial muscles? - abductor pollicis longus - extensor pollicis longus/brevis - extensor indicis
Where do 8 of the 12 posterior compartment muscles attach? lateral epicondyle of the humerus
What are the actions/functions of the posterior antebrachial muscles? wrist and finger extension
What are the movements of the wrist joint? - flexion/extension - abduction/adduction
What are the movements of the metacarpophalangeal joint? - flexion/extension - abduction/adduction
What are the movements of the interphalangeal joint? - flexion/extension
What are the movements of the carpometacarpal joint? - flexion/extension - abduction/adduction - opposition/reposition
