Brachial artery

The artery of the arm. It continues the axillary artery at the lower border of teres major and ends opposite the neck of the radius by dividing into the radial and ulnar arteries.

Key points

• Teres major → neck of the radius (divides into radial + ulnar).
• Median nerve crosses it lateral → medial.
• Profunda brachii runs with the radial nerve.
• Under the bicipital aponeurosis in the cubital fossa.
• Upper limb axis artery: 7th cervical intersegmental.
• Radial and ulnar arteries appear late.
• Artery: intima / media (smooth muscle) / adventitia.
• Most named arteries are muscular; aorta is elastic.
