Elbow Flashcards
Biceps Brachii Origin
Short head arises from a shared tendon with coracobrachiallis from the apex of the coracoid process.
the long head from the supraglenoid tubercle of the scapula and adjacent glenoid labrum,
the tendon run in the inter tubercular groove and descends
Biceps Brachii Insertion
the posterior part of the radial tuberosity
Brachiallis Origin
Lies under Biceps, arises from the distal 2/3 of the medial and lateral inter muscular septum on the humerus
Brachiallis Insertion
inferior part of the coronoid process and the tubersity of the ulna.
Brachioradiallis Origin
upper 2/3rds of the front and of the lateral supracondylar ridge of the humerus and adjacent intermuscular septum
Brachioradillais insertion
lateral surface of the radius jus above the styloid process.
Biceps Brachii
Brachoradiallis
Brachiallis
all do what?
flex the elbow
Cubital Fossa
the cubital fossa is a triangle on the anterior aspect of the arm. where the medial epicondyle of the radius forms the superior aspect, the brachioradilalis forms the lateral border, and pronator teres forms the medial border.
what is the cubital fossa
it is a passageway that structures pass through.
Tricpes Brachii Origin
Long head - infraglenoid tubercle ion the scapula.
Lateral Head - above and lateral the spiral groove on the posterior surface of the humerus.
Medial Head - poster surface of the humerus below and medial to the spiral groove additional attachment to the lateral and medial inter muscular septa.
all form one tendon.
Triceps Insertion
olecranon on the ulna.
Anconeous Origin
posterior surface of the lateral epicondyle.
Anconeous Insertion
lateral surface of the olecranon and upper quarter of the posterior surface of the ulna.
Supinator Origin
inferior aspect of the lateral epicondyle of the humerus and the supinator crest and fossa of the ulna.
Supinator Insertion
posterior, lateral and anterior aspect of the radius.
