Document Summary
There are two fundamentally different kinds of structures in the nervous system: those that are largely composed of cell bodies and those that are largely composed of axons. Perform local analysis of neural signals, composed of many neurons with very short axons/no axons. Conduct action potentials from one part of the nervous system to another. * the word nucleus" has two different neuroanatomical meanings, in this case it is referring to a cluster of cell bodies in the cns, it could also refer to the large spherical structure of the neural cell body. Each major nucleus, ganglion, tract, and nerve is composed of hundreds of thousands of individual neurons. The two hemispheres of the brain are separated by a long deep chasm called the longitudinal fissure along the midline of the brain. There are a few large tracts that span the longitudinal fissure and connect the cerebral hemispheres.
