Part of the basal ganglia of the brain. The basal ganglia are interconnected masses of gray matter located in the interior regions of the cerebral hemispheres and in the upper part of the brainstem.
The striatum is also called the striate body. It includes the caudate nucleus and the lentiform nucleus. The term striatum (striate) refers to the layered appearance of bands of gray matter that course from one of these nuclei to the other and represent the connections between them.
An abnormal narrowing of a body passage, especially a tube or a canal. The stricture may be due, for example, to scar tissue or to a tumor. Stricture refers to both the process of narrowing and the narrowed part itself.

Acute, complete obstruction of the esophagus occurs when food (usually meat) is lodged in the esophageal stricture. Patients experience chest pain, and are unable to swallow saliva. Attempts to relieve the obstruction […]
- Striopallidodentate calcinosis
Striopallidodentate (SPD) calcinosis, a condition first described in 1930 by T. Fahr and therefore called Fahr syndrome, is a genetic (inherited) neurological disorder characterized by abnormal deposits of calcium in certain of areas of the brain (including the basal ganglia and the cerebral cortex). Symptoms may include motor function deterioration, dementia, mental retardation, spastic paralysis, […]
Surgery to treat varicose veins. The problematic veins are “stripped” out by passing a flexible device through the vein and removing it through an incision near the groin. Smaller tributaries of these veins also are stripped with this device or removed through a series of small incisions. Those veins that connect to the deeper veins […]
The sudden death of brain cells due to lack of oxygen, caused by blockage of blood flow or rupture of an artery to the brain. Sudden loss of speech, weakness, or paralysis of one side of the body can be symptoms. A suspected stroke can be confirmed by scanning the brain with special X-ray tests, […]
