Medical providers divide the spinal cord into four distinct regions. Knowing the region in which the injury is located is often the key to understanding diagnosis and treatment. The four spinal cord regions are: The cervical spinal cord: This is the topmost portion of the spinal cord, where the brain connects to the spinal cord, and the neck connects to the back. This region consists of eight vertebrae, commonly referred to as C1-C8. All spinal cord numbers are descending, so C1 is the highest vertebra, while C8 is the lowest in this region. The thoracic spinal cord: This section forms the middle of the spinal cord, containing twelve vertebrae numbered T1-T12. The lumbar spinal cord: This is a lower region of the spinal cord, where your spinal cord begins to bend. If you put your hand in your lower back, where your back bends inward, you're feeling your lumbar region. There are five lumbar vertebrae, numbered L1-L5.

Pericarditis is an inflammation of the lining surrounding the heart (the pericardial sac). Pericardial effusion is a collection of fluid in the pericardial sac. This fluid may be produced by inflammation. The cause of pericarditis in most individuals is unknown but is likely due to viral infection.

An omentectomy is a surgical procedure designed to remove the omentum, which is a thin fold of abdominal tissue that encases the stomach, large intestine and other abdominal organs. This fatty lining contains lymph nodes, lymph vessels, nerves and blood vessels.
Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems. Sometimes, however, one or more of the pouches become inflamed or infected. That condition is known as diverticulitis (die-vur-tik-yoo-LIE-tis). Diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits. Mild diverticulitis can be treated with rest, changes in your diet and antibiotics. Severe or recurring diverticulitis may require surgery.
This video: Blisters caused by friction or minor burns do not require a doctor's care. New skin will form underneath the affected area and the fluid is simply absorbed. Do not puncture a blister unless it is large, painful, or likely to be further irritated. The fluid-filled blister keeps the underlying skin clean, which prevents infection and promotes healing.
During normal sleep, you cycle through REM and four stages of non-REM (NREM) sleep numerous times a night. Stage 1 of NREM sleep is the lightest, while stage 4 is the deepest. When you're repeatedly interrupted and can't cycle normally through these types and stages of sleep, you may feel tired, fatigued, and have trouble concentrating and paying attention while you're awake. Sleepiness puts you at greater risk for car wrecks and other accidents.
