How your ear works
How your ear works samer kareem 16,327 Views • 3 years ago

Sound waves enter the ear canal and make the ear drum vibrate. This action moves the tiny chain of bones (ossicles – malleus, incus, stapes) in the middle ear. The last bone in this chain 'knocks' on the membrane window of the cochlea and makes the fluid in the cochlea move.

Cerebral Aneurysm
Cerebral Aneurysm samer kareem 2,077 Views • 3 years ago

What is an Aneurysm? A cerebral or intracranial aneurysm is an abnormal focal dilation of an artery in the brain that results from a weakening of the inner muscular layer (the intima) of a blood vessel wall. The vessel develops a "blister-like" dilation that can become thin and rupture without warning. The resultant bleeding into the space around the brain is called a subarachnoid hemorrhage (SAH). This kind of hemorrhage can lead to a stroke, coma, and/or death. Aneurysms are usually found at the base of the brain just inside the skull, in an area called the subarachnoid space. In fact, 90 percent of SAHs are attributed to ruptured cerebral aneurysms and the two terms are often used synonymously.

Bronchial Asthma
Bronchial Asthma samer kareem 4,816 Views • 3 years ago

Asthma is a condition in which your airways narrow and swell and produce extra mucus. This can make breathing difficult and trigger coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack. Asthma can't be cured, but its symptoms can be controlled. Because asthma often changes over time, it's important that you work with your doctor to track your signs and symptoms and adjust treatment as needed.

Superior Vena Cava Syndrome
Superior Vena Cava Syndrome samer kareem 1,429 Views • 3 years ago

The superior vena cava is a major vein in a person's body. It carries blood from the head, neck, upper chest, and arms to the heart. Superior vena cava syndrome (SVCS) occurs when a person's superior vena cava is partially blocked or compressed. Cancer is usually the main cause of SVCS.

Clopidogrel
Clopidogrel samer kareem 1,958 Views • 3 years ago

Clopidogrel keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions. Clopidogrel is used to prevent blood clots after a recent heart attack or stroke, and in people with certain disorders of the heart or blood vessels. Clopidogrel may also be used for other purposes not listed in this medication guide

Dental implant surgery.
Dental implant surgery. samer kareem 2,813 Views • 3 years ago

Dental implant surgery is a procedure that replaces tooth roots with metal, screwlike posts and replaces damaged or missing teeth with artificial teeth that look and function much like real ones. Dental implant surgery can offer a welcome alternative to dentures or bridgework that doesn't fit well. How dental implant surgery is performed depends on the type of implant and the condition of your jawbone. Dental implant surgery may involve several procedures. The major benefit of implants is solid support for your new teeth — a process that requires the bone to heal tightly around the implant. Because this healing requires time, the process can take many months.

What is Nightmare Disorder?
What is Nightmare Disorder? samer kareem 1,689 Views • 3 years ago

There can be a number of psychological triggers that cause nightmares in adults. For example, anxiety and depression can cause adult nightmares. Post-traumatic stress disorder (PTSD) also commonly causes people to experience chronic, recurrent nightmares. Nightmares in adults can be caused by certain sleep disorders

Heart Bypass Surgery (CABG)
Heart Bypass Surgery (CABG) samer kareem 2,090 Views • 3 years ago

Coronary artery bypass graft surgery (CABG) is a procedure used to treat coronary artery disease. Coronary artery disease (CAD) is the narrowing of the coronary arteries – the blood vessels that supply oxygen and nutrients to the heart muscle. CAD is caused by a build-up of fatty material within the walls of the arteries. This build-up narrows the inside of the arteries, limiting the supply of oxygen-rich blood to the heart muscle. One way to treat the blocked or narrowed arteries is to bypass the blocked portion of the coronary artery with a piece of a healthy blood vessel from elsewhere in the body. Blood vessels, or grafts, used for the bypass procedure may be pieces of a vein from the legs or an artery in the chest. An artery from the wrist may also be used. One end of the graft is attached above the blockage and the other end is attached below the blockage. Blood is routed around, or bypasses, the blockage by going through the new graft to reach the heart muscle. This is called coronary artery bypass surgery. Traditionally, to bypass the blocked coronary artery, a large incision is made in the chest and the heart is temporarily stopped so that the surgeon can perform the delicate procedure. To open the chest, the breastbone (sternum) is cut in half and spread apart. Once the heart is exposed, tubes are inserted into the heart so that the blood can be pumped through the body by a cardiopulmonary bypass machine (heart-lung machine). The bypass machine is necessary to pump blood while the heart is stopped and kept still in order for the surgeon to perform the bypass operation. While the traditional "open heart" procedure is still commonly done and often preferred in many situations, less invasive techniques have been developed to bypass blocked coronary arteries. "Off-pump" procedures, in which the heart does not have to be stopped, were developed in the 1990's. Other minimally invasive procedures, such as keyhole surgery (performed through very small incisions) and robotic procedures (performed with the aid of a moving mechanical device), may be used.

Multiple Myeloma Video
Multiple Myeloma Video samer kareem 2,366 Views • 3 years ago

This video: Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Plasma cells help you fight infections by making antibodies that recognize and attack germs. Multiple myeloma causes cancer cells to accumulate in the bone marrow, where they crowd out healthy blood cells. Rather than produce helpful antibodies, the cancer cells produce abnormal proteins that can cause kidney problems. Treatment for multiple myeloma isn't always necessary. If you're not experiencing signs and symptoms, you may not require treatment. If signs and symptoms develop, a number of treatments can help control your multiple myeloma.

Normal and Abnormal Heart Sounds
Normal and Abnormal Heart Sounds samer kareem 4,536 Views • 3 years ago

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation, an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding the condition of the heart. In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heartbeat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the atrioventricular valves and semilunar valves, respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.

Uterine Rupture

Uterine rupture is usually when the scar from your previous caesarean section tears open. Though it's uncommon, you should be aware of this risk, particularly if you're thinking about giving birth vaginally next time. It's possible for your scar to gape slightly while you're pregnant (scar dehiscence).

Polycythemia Vera
Polycythemia Vera samer kareem 2,644 Views • 3 years ago

This video: Polycythemia vera (pol-e-sigh-THEE-me-uh VEER-uh) is a slow-growing type of blood cancer in which your bone marrow makes too many red blood cells. Polycythemia vera may also result in production of too many of the other types of blood cells — white blood cells and platelets. These excess cells thicken your blood and cause complications, such as such as a risk of blood clots or bleeding. Polycythemia vera isn't common. It usually develops slowly, and you may have it for years without noticing signs or symptoms. Often, polycythemia vera is found during a blood test done for some other reason. Without treatment, polycythemia vera can be life-threatening. However, with proper medical care, many people experience few problems related to this disease. Over time, there's a risk of progressing to more-serious blood cancers, such as myelofibrosis or acute leukemia.

Blocked Arteries in Legs
Blocked Arteries in Legs samer kareem 13,612 Views • 3 years ago

This video: Claudication is pain caused by too little blood flow, usually during exercise. Sometimes called intermittent claudication, this condition generally affects the blood vessels in the legs, but claudication can affect the arms, too. At first, you'll probably notice the pain only when you're exercising, but as claudication worsens, the pain may affect you even when you're at rest. Although it's sometimes considered a disease, claudication is technically a symptom of a disease. Most often, claudication is a symptom of peripheral artery disease, a potentially serious but treatable circulation problem in which the vessels that supply blood flow to your legs or arms are narrowed. Fortunately, with treatment, you may be able to maintain an active lifestyle without pain.
