It then spreads down the bundle of his and then purkinje fibres to cause ventricular contraction. So when viewing the heart from the front, the direction of depolarisation is 11 o'clock to 5 o'clock. The general direction of depolarisation is known as the cardiac axis.

A facet joint injection is a relatively simple, straightforward procedure, and is usually performed in an office based procedure suite or in an ambulatory surgical center. As with many spinal injections, facet joint injections are best performed using fluoroscopy (live X-ray) for guidance to properly target and place the needle (and to help avoid nerve injury or other injury).

Mesentery - A New Organ Identified In Human Body
Mesentery - A New Organ Identified In Human Body Scott 10,168 Views • 3 years ago

an. 4, 2017 -- Scientists say they've identified a new organ in the body -- a swath of tissue dubbed the mesentery that connects the intestine to the abdomen and holds everything in place. For years, anatomical experts have thought the organ was composed of several different segments of tissue, as opposed to being one single structure, according to Discover magazine. Since an organ must be one structure that performs a vital function, it was not deemed worthy of organ status. But recent research from doctors at the University Hospital Limerick in Ireland shows that the mesentery is actually one single band of tissue, the magazine reported Tuesday. It begins at the pancreas and wraps around the small intestine and colon. Its purpose: to hold these organs in position so they can perform their respective functions. "Without it you can't live," lead researcher Dr. J. Calvin Coffey, a colorectal surgeon at Limerick, told the magazine. "There are no reported instances of a Homo sapien living without a mesentery." "Understanding how and why our digestive system is arranged the way it is could be crucial to our understanding of diseases like Crohn's and irritable bowel syndrome," Coffey added. "There are a lot of diseases that we are stalled on, and we need to refresh our approach to these diseases," Coffey said. "Now that we've clarified its [the mesentery's] structure, we can systematically examine it. We're at a very exciting place right now." The discovery was published recently in the Lancet Gastroenterology & Hepatology journal.

Endometriosis (en-doe-me-tree-O-sis) is an often painful disorder in which tissue that normally lines the inside of your uterus — the endometrium — grows outside your uterus. Endometriosis most commonly involves your ovaries, fallopian tubes and the tissue lining your pelvis. Rarely, endometrial tissue may spread beyond pelvic organs.

Aortic Heart Valve Replacement Surgery
Aortic Heart Valve Replacement Surgery samer kareem 10,868 Views • 3 years ago

During open-heart valve surgery, the doctor makes a large incision in the chest. Blood is circulated outside of the body through a machine to add oxygen to it (cardiopulmonary bypass or heart-lung machine). The heart may be cooled to slow or stop the heartbeat so that the heart is protected from damage while surgery is done to replace the valve with an artificial valve. The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig.

Heparin Induced Thrombocytopenia (HIT)
Heparin Induced Thrombocytopenia (HIT) samer kareem 9,389 Views • 3 years ago

All forms of heparin (including low-molecular-weight heparin such as enoxaparin) must be stopped immediately in patients with suspected heparin-induced thrombocytopenia (HIT) while awaiting diagnostic confirmation. Patients with HIT remain at high risk of thrombosis even after discontinuation of heparin. Therefore, an alternate, rapidly acting, non-heparin anticoagulant such as direct thrombin inhibitor (eg, argatroban, bivalirudin) must be started immediately.

Cardiac arrest usually results from an electrical disturbance in the heart. It's not the same as a heart attack. The main symptom is loss of consciousness and unresponsiveness. This medical emergency needs immediate CPR or use of a defibrillator. Hospital care includes drugs, an implantable device, or other procedures.

Why Do We Vomit? samer kareem 5,315 Views • 3 years ago

The timing of the nausea or vomiting can indicate the cause. When appearing shortly after a meal, nausea or vomiting may be caused by food poisoning, gastritis (inflammation of the stomach lining), an ulcer, or bulimia. Nausea or vomiting one to eight hours after a meal may also indicate food poisoning.

Hypothalamus and Pituitary
Hypothalamus and Pituitary samer kareem 4,519 Views • 3 years ago

The pituitary gland is often portrayed as the "master gland" of the body. Such praise is justified in the sense that the anterior and posterior pituitary secrete a battery of hormones that collectively influence all cells and affect virtually all physiologic processes. The pituitary gland may be king, but the power behind the throne is clearly the hypothalamus. As alluded to in the last section, some of the neurons within the hypothalamus - neurosecretory neurons - secrete hormones that strictly control secretion of hormones from the anterior pituitary. The hypothalamic hormones are referred to as releasing hormones and inhibiting hormones, reflecting their influence on anterior pituitary hormones.

A hemolytic transfusion reaction is a serious complication that can occur after a transfusion of blood. The red blood cells that were given in the transfusion are destroyed by the patient's immune system. There are other types of allergic transfusion reactions that do not cause hemolysis.
