What is a radical neck dissection? The surgeon removes a block of tissue from the collarbone to the jaw and from the front to the back of the neck. The large muscle on the side of the neck that is used for rotating, flexing or extending the neck is also taken out, along with the major vein on the side of the neck. Sometimes, a less drastic operation, called a supraomohyoid neck dissection is done. This takes out only the lymph nodes, the tissue surrounding the nodes and a muscle at the front of the neck. Another technique, called a functional neck dissection, saves the muscles of the neck, taking out only the lymph nodes and tissues surrounding them.
What kind of incision is made with a radical neck dissection? The incision depends upon what the surgery is for. It can run from below the ear to the collarbone. Everything in the front of the neck on one side or on both sides may be removed. This may include the lymph nodes, blood vessels, nerves, and the salivary gland under the jawbone.

Is stress bad for your heart?

Can stress really damage the heart? 
It certainly can, and by many different mechanisms. Stress that isn’t handled well, especially if accompanied by bouts of anger, can increase the outpouring of the stress hormones, such as cortisol, adrenaline, and noradrenaline, all from the adrenal gland the small powerhouse gland that sits on top of our kidneys. Stress hormones can do the following:

• increase pulse rate and blood pressure
• push up triglyceride levels
• increase the clotting tendency of our blood
• increase the chances of rupturing one of the plaques, which can be a cause of an acute heart attack •cause an arrhythmia (an abnormal rapid heartbeat), which can also trigger a heart attack.
