What are the chief cells of the brain and spinal cord?
The chief cells of the brain and spinal cord are the neurons, which receive and transmit neural impulses . Each neuron has a body which is its micro-command center, and it has a gray color when observed microscopically. The neurons possess two or more neural processes that stem from the body and relay the neural information. The neural processes are divided into short ( dendrites) and long ( axons ). Most of the axons are ensheathed by a substance called myelin, which gives them a distinguishable white color.
How do the brain and spinal cord communicate?
While analyzing the information and preparing adequate body responses, the parts of the brain and spinal cord communicate with each other via many neural pathways. Once the final output is ready, they convey it to the rest of the body via nerves of the peripheral nervous system (PNS), which stem directly from them.
