Though you might think of your spinal cord as one single piece, it's actually a column of nerves protected by a sheath of myelin and then further secured by 31 butterfly-shaped vertebrae (singular: vertebra). 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.

Multiple sclerosis (MS) is a potentially disabling disease of the brain and spinal cord (central nervous system). In MS, the immune system attacks the protective sheath (myelin) that covers nerve fibers and causes communication problems between your brain and the rest of your body. Eventually, the disease can cause the nerves themselves to deteriorate or become permanently damaged. Signs and symptoms of MS vary widely and depend on the amount of nerve damage and which nerves are affected. Some people with severe MS may lose the ability to walk independently or at all, while others may experience long periods of remission without any new symptoms. There's no cure for multiple sclerosis. However, treatments can help speed recovery from attacks, modify the course of the disease and manage symptoms

Overview HIV is a virus that affects the immune system, specifically the CD4 cells. The CD4 cells help protect the body from illness. Unlike other viruses that the immune system can fight off, HIV can’t be eliminated by the immune system. The symptoms of HIV can vary greatly from person to person. No two people with HIV will likely experience the exact same symptoms. However, HIV will generally follow this pattern: acute illness asymptomatic period advanced infection Acute illness Approximately 80 percent of people who contract HIV experience flu-like symptoms within two to four weeks. This flu-like illness is known as acute HIV infection. Acute HIV infection is the primary stage of HIV and lasts until the body has created antibodies against the virus. The most common symptoms of this stage of HIV include: body rash fever sore throat severe headaches Less common symptoms may include: fatigue swollen lymph nodes ulcers in the mouth or on the genitals muscle aches joint pain nausea and vomiting night sweats Symptoms typically last one to two weeks. Anyone who has these symptoms and thinks they may have contracted HIV should consider scheduling an appointment with their healthcare provider to get tested. Symptoms specific to men Symptoms of HIV are generally the same in women and men. One HIV symptom that is unique to men is an ulcer on the penis. HIV may lead to hypogonadism, or poor production of sex hormones, in either sex. However, hypogonadism’s effects on men are easier to observe than its effects on women. Symptoms of low testosterone, one aspect of hypogonadism, can include erectile dysfunction (ED).

Most people develop several moles (nevi) throughout adulthood. Moles can be found anywhere on the body, usually in sun-exposed areas, and are usually brown, smooth, and slightly raised. In most cases, a nevus is benign and doesn't require treatment. Rarely, they turn into melanoma or other skin cancers. A nevus that changes shape, grows bigger, or darkens should be evaluated for removal.

The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.
