The radial nerve can be damaged if the humerus ( the bone of the arm ) is broken, because it runs through the radial groove on the lateral border of this bone along with the deep brachial artery.
32.
The nerve then runs down the ulnar side of the arm medial to the brachial artery, pierces the deep fascia with the basilic vein, about the middle of the arm, and divides into a volar and an ulnar branch.
33.
When blood flow is present, but restricted, the cuff pressure, which is monitored by the pressure sensor, will vary periodically in synchrony with the cyclic expansion and contraction of the brachial artery, i . e ., it will oscillate.
34.
The first replantation to be performed in the world involved repair of the brachial artery and was done by a team of chief residents led by Dr . Ronald Malt at Massachusetts General Hospital in Boston, Massachusetts, United States in 1962.
35.
An arterial line is usually inserted into the radial artery in the wrist, but can also be inserted into the brachial artery at the elbow, into the femoral artery in the groin, into the dorsalis pedis artery in the foot, or into the ulnar artery in the wrist.
36.
Historically, when ( venous ) blood-letting was practiced, the bicipital aponeurosis ( the ceiling of the cubital fossa ) was known as the " grace of God " tendon because it protected the more important contents of the fossa ( i . e . the brachial artery and the median nerve ).
37.
In 1950, researchers at the Cleveland City Hospital ran experiments to study changes in cerebral blood flow : they injected people with spinal anesthesia, and inserted needles into their jugular veins and brachial arteries to extract large quantities of blood and, after massive blood loss which caused paralysis and fainting, measured their blood pressure.
38.
Blood pressure should not be taken on the arm with a PICC, which is a problem if there are reasons not to take pressure on the other arm, such as a dialysis shunt, absence, cast, infection, lymph node removal, etc . Blood pressure readings on legs are often 10 20 % higher than those on the brachial artery.
39.
Fistulas are usually created in the nondominant arm and may be situated on the hand ( the'snuffbox'fistula'), the forearm ( usually a "'radiocephalic "'fistula, or so-called Brescia-Cimino fistula, in which the radial artery is anastomosed to the cephalic vein ), or the elbow ( usually a brachiocephalic fistula, where the brachial artery is anastomosed to the cephalic vein ).
40.
It descends along the medial side of the brachial artery to the middle of the arm, where it pierces the deep fascia, and is distributed to the skin of the back of the lower third of the arm, extending as far as the elbow, where some filaments are lost in the skin in front of the medial epicondyle, and others over the olecranon.
