What does the brachial artery bifurcates into?
What does the brachial artery bifurcates into?
What does the brachial artery bifurcates into?
The brachial artery bifurcates to form the radial artery and ulnar artery in the cubital fossa at the level of the radial neck, below the bicipital aponeurosis 1.
Which artery extends as the brachial artery?
The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle….

Can you have two brachial arteries?
Normally there is a single brachial artery and their branches supply the upper limb. When two brachial arteries are present, one runs a superficial course and is called superficial brachial artery (SBA). The other takes a deep course and is known as deep brachial artery (DBA).
What are the two main arteries in the arm?
Brachial Artery: This artery begins under the pectoralis muscle and travels down the arm. It eventually splits into two arteries (the radial artery and the ulnar artery) at the elbow.
Where does the brachial artery split?
[1] These branching arteries include the deep brachial artery, the superior ulnar collateral artery, and the inferior ulnar collateral artery. Once the brachial artery reaches the cubital fossa, it divides into its terminal branches: the radial and ulnar arteries of the forearm.
What is a brachial vein?
Brachial vein: A vein that accompanies the brachial artery between the shoulder and the elbow. The route of the brachial artery is from the shoulder down to the elbow whereas that of the brachial vein is in the reverse direction — from the elbow back up to the shoulder.
What nerve accompanies the brachial artery?
The median nerve, a division of the brachial plexus, initially lies lateral to the brachial artery at its proximal segment. At its distal segment, the median nerve crosses the medial side of the brachial artery and lies in the ventral cubital fossa.
What does the brachial vein do?
‘ It drains the lateral aspect of the arm and forearm and also forms communications with the deep venous system. The basilic vein- This vein runs down the ulnar side of the arm, and also helps in draining the dorsal venous network of the hand.
Where does the brachial artery lead to?
The Anatomy of the Brachial Artery It connects the lower margin of the Teres major tendon in the shoulder to the elbow. Working its way down the upper arm, it becomes part of the cubital fossa, a triangular depression on the inside of the elbow joint, where it splits into further arteries.
What nerve runs with brachial artery?
Where does the brachial artery split in the arm?
It then divides into the radial and ulnar arteries which run down the forearm. In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm.
What kind of veins are in the brachial artery?
This space contains the brachial artery, with its accompanying veins; the radial and ulnar arteries; the median and radial nerves; and the tendon of the Biceps brachii.
Where is the right brachial artery located?
The brachial artery is a major blood vessel located in the upper arm and is the main supplier of blood to the arm and hand. The brachial artery continues from the axillary artery at the shoulder and travels down the underside of the arm.
How is circulation maintained in the brachial artery?
If the artery be tied below the origin of the profunda brachii and superior ulnar collateral, the circulation is maintained by the branches of these two arteries anastomosing with the inferior ulnar collateral, the radial and ulnar recurrents, and the dorsal interosseous.
It then divides into the radial and ulnar arteries which run down the forearm. In some individuals, the bifurcation occurs much earlier and the ulnar and radial arteries extend through the upper arm.
