Brachial Artery Applied Anatomy

• Blood pressure is recorded by auscultating the pulsations of brachial artery in the cubital fossa medial to tendon of biceps brachii.
• The brachial artery can be compressed digitally at midarm against the tendon of the coracobrachialis on the medial side of the humerus.
• The brachial artery may be ruptured in a supracondylar fracture of the humerus.
