Arm (Brachium) and Cubital Fossa

• on the humerus. 
• medial is the ulnar side and lateral is the radius side

articulates with the depression of the head of the radius to allow for flexion and extension; rotational movement of the forearm

allows for the pronation and supination of the forearm

• Coracobrachialis
• brachialis
• biceps brachii

• composed of Short (medial )
• long head(lateral)
• - the tendon of the long head goes through the sulcus of the humerus to the transvers humeral ligament, passes through the glenohumeral joint and attahches at the suprglenoid tubercle

• Innervation: musculocutaneous nerve 
• artery:Brachial artery  or anterior circumflex humeral artery
• movement: adducts and flexes the humerus

• innerv: musculocutaneous nerves
• artery:Brachial artery and anterior circumflex humeral artery 
• movement: supinates and flexes the forearm

• innervation: musculocutaneous nerve
• artery: brachial artery or anterior circumflex humeral artery 
• movement: flexes the forearm

• only contains the triceps brachii 
• it extends the forear
• innervation: radial nerve
• artery: posteriorcircumflex humeral artery

• an extension of the biceps tendon
• attached to the antebrachial fascia
• seperates the medial cubital  vein from the brachial artery and median nerve
• This shy it is a safe place for venipuncture

• course to the biceps brachii muscle within the medial intermuscular septum 
• arises from the brachial plexus

• courses in the medial intermuscular septum in the proximal arm
• the funny bone

• it is a continuation of the axillary artery 
• it branches into the ulnary artery and radial artery

• there are 3 
• deep artery of the arm 
• superior ulnar collateral
• interior ulnar collateral

it changes to the axillary vein

• bounded to 
• brachiradialis muschle (laterally )
• & pronator tere muscles ( medially)
• superficial boundary ot roof of cubital foassa is the antebrachial fossa
• deep boundary  ( floor of the cubital fossa) is the brachialis and supinator muscles

• TAN
• tendon, artery, nerve
• biceps brachii tendon
• brachial artery 
• median nerve
