Elbow Flashcards
Brachialis
Distal half of humerus , anterior surface
Coronoid process and ulnar tuberosity
Elbow flexion
Musculocutaneous nerve C5 -C6
Biceps
Longhead: supraglenoid tubercle of scapula
Short head : coracoid process of scapula
Radial tuberosity of the radius
Elbow flexion format supination
Musculocutaneous nerve C5-C6
Brachioradialis
Lateral suprecondylar ridge on the humerus
Styloid process of the radius
Elbow flexion
Radial nerve C5,c6
Triceps
Long head: infraglenoid tubercle of the scapula
Lateral head: Inferior to greater tubercle on posterior humerus
Medial head: posterior surface of humerus
Olecranon process of ulna
Elbow extension
Radial nerve C5 C6
Anconeus
Lateral epicondyle of humerus
Lateral and inferior to olecranon process of ulna
Assists in elbow extension ; keeps joint capsule from being pinched by the olecranon fossa during extension
Radial Nerve C6 C7 c8
Pronator teres
Medial condyle of humerus and coronoid process of ulna
Lateral aspect of radius at its midpoint
Forearm pronation , assists in elbow flexion
Median nerve C6 C7
Pronator Quadratus
Distal one fourth of ulna
Distal one fourth of radius
Forearm probation
Median nerve C8 T1
Supinator
Lateral epicondyle of humerus and adjacent ulna
Anterior surface of the proximal radius
Forearm supination
Radial nerve C6
