Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which carries sensation from your face to your brain. If you have trigeminal neuralgia, even mild stimulation of your face — such as from brushing your teeth or putting on makeup — may trigger a jolt of excruciating pain. You may initially experience short, mild attacks. But trigeminal neuralgia can progress and cause longer, more-frequent bouts of searing pain. Trigeminal neuralgia affects women more often than men, and it's more likely to occur in people who are older than 50. Because of the variety of treatment options available, having trigeminal neuralgia doesn't necessarily mean you're doomed to a life of pain. Doctors usually can effectively manage trigeminal neuralgia with medications, injections or surgery.

A tissue is a group of cells that has a similar structure and acts together to perform one or more specific functions. In this tutorial, we will introduce you to the 4 main types of tissues in the human body: epithelial tissue, connective tissue, muscle tissue and nervous tissue. Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules, whereas connective tissue underlies and supports other tissue types.
Muscle tissue contracts to initiate movement in the body and nervous tissue transmits and integrates information through the central and peripheral nervous systems.
In this video tutorial we will take a closer look at the histology of the main cells and tissues under the microscope.

Focal seizures (also called partial seizures [citation needed] and localized seizures) are seizures which affect initially only one hemisphere of the brain. [citation needed] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes.
Lumpectomy means that a focal area of cancer is going to be removed. A lot of patients with a lumpectomy don’t need any specific breast reconstruction, explains Dr. Miguel Angel Medina, Director of Microsurgery with Miami Cancer Institute.
Al the end of surgical treatment, all those patients go on to need radiation therapy. For patients who have large breasts, physicians have to take a larger lumpectomy than normal.
The dural venous sinuses are spaces between the endosteal and meningeal layers of the dura. They contain venous blood that originates for the most part from the brain or cranial cavity. The sinuses contain an endothelial lining that is continuous into the veins that are connected to them.
There are three main types of lung cancer. Knowing which type you have is important because it affects your treatment options and your outlook (prognosis). If you aren’t sure which type of lung cancer you have, ask your doctor so you can get the right information.
