First, the internal capsule 1. The concept of internal capsule, location and structure Talking about the internal capsule, we must review the internal structure of the cerebral hemispheres. As we all know, the human nervous system consists of nerve cells and glial cells. Nervous system is the basic structure and function of the nervous system, also known as neurons. Each nerve cell by the cell body and protrusions of two parts. Protrusion of nerve cells, also known as nerve fibers. Although glial cells also exist in the nervous system, but only play a supporting and nutritional role of nerve cells, does not have the neuron has the function. In the central nervous system, the area where nerve cell bodies are clustered, the color is gray, is called gray matter; the area where nerve fibers are concentrated, the color
