This video also briefly talks about muscle naming, some vocabulary (such as agonists and antagonists) before focusing on the sliding filament model. Video also mentions general roles of tropomyosin and troponin.

What Causes Ulcers? No single cause has been found for ulcers. However, it is now clear that an ulcer is the end result of an imbalance between digestive fluids in the stomach and duodenum. Most ulcers are caused by an infection with a type of bacteria called Helicobacter pylori (H. pylori). Factors that can increase your risk for ulcers include: Use of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen (Aleve, Anaprox, Naprosyn, and others), ibuprofen (Motrin, Advil, some types of Midol, and others), and many others available by prescription; even safety-coated aspirin and aspirin in powered form can frequently cause ulcers. Excess acid production from gastrinomas, tumors of the acid producing cells of the stomach that increases acid output (seen in Zollinger-Ellison syndrome) Excessive drinking of alcohol Smoking or chewing tobacco Serious illness Radiation treatment to the area What Are the Symptoms of an Ulcer? An ulcer may or may not have symptoms. When symptoms occur, they may include: A gnawing or burning pain in the middle or upper stomach between meals or at night Bloating Heartburn Nausea or vomiting In severe cases, symptoms can include: Dark or black stool (due to bleeding) Vomiting blood (that can look like "coffee-grounds") Weight loss Severe pain in the mid to upper abdomen

systemic inflammatory response syndrome (SIRS). This is most likely secondary to sepsis from an infection of the patient's Hickman catheter given the associated skin findings, although culture results are needed to confirm this diagnosis. The patient's low blood pressure is likely secondary to developing septic shock, and he has already appropriately been treated with intravenous fluids. Catheter removal is indicated given his hemodynamic instability. Catheter removal is also indicated in patients with severe sepsis with organ hypoperfusion, endocarditis, suppurative thrombophlebitis, or persistent bacteremia after 72 hours of appropriate antibiotic therapy. Long term catheters should also be removed if culture results are positive for S. aureus, P. aeruginosa, fungi, or mycobacteria.

Most C-sections are done under regional anesthesia, which numbs only the lower part of your body — allowing you to remain awake during the procedure. A common choice is a spinal block, in which pain medication is injected directly into the sac surrounding your spinal cord
