| Question | Answer |
|---|---|
| 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 |
