人体解剖学电子复习题第11章中枢神经系统（Human anatomy electronic review eleventh chapter central nervous system） 1. neurons: also known as nerve cells, is composed of the basic structure and function of the nervous system unit, by the soma and protrusion of two parts. 2. synapse: the specialized contact area between neuron and neuron or between neuron and effector. According to the way of nerve conduction, the synapse can be divided into two kinds: electrical synapse and chemical synapse. 3. nerve conduction bundle: a bundle of nerve fibers in the central nervous system that starts, travels, and functions as a nerve conduction bundle (Xian Weishu). 4. nerve fibers: axons of nerve cells and long lateral branches, often surrounded by myelin and nerve membranes, called nerve fibers. It can be divided into two categories: pulp and marrow. 5. white matter: in the central nervous system, nerve fiber collection place, the color is bright, is called the white matter. 6. gray matter: in the central nervous system, the collection of nerve cell bodies and dendrites, dark gray color, known as gray matter. 7. cerebral cortex: the gray matter on the surface of the large cerebellum is called the cortex. 8. nerve nucleus: in the central nervous system, the cellular bodies of similar morphology and function gather into a mass, dispersed in the white matter, called the nucleus of the nerve. 9. ganglion: in the peripheral nervous system, the neuronal cell body gathers together, forms the knot like structure, calls the ganglion, has the sensory ganglion and the splanchnic ganglion two kinds. 10. nerve: in the peripheral nervous system, nerve fibers collect into bundles, and the outer membrane is called nerve. 11. network structure: in the spinal cord, brain stem and other places, there is a mix of gray and white matter interwoven structure, known as network structure. 12. limbic system: in the cerebral hemisphere, the lateral, cingulate gyrus, parahippocampal gyrus, hook and hippocampus, and so into a ri
