Chapter 11.4: Nervous System
Table of Contents:
The nervous system is crucial to every bodily function we perform. In this chapter we’ll look into the details of this system.
The neuron is the basic functional unit of the nervous system. There are three main structural parts of a neuron:
- The cell body of the neuron is called the soma. It contains the nucleus of the neuron.
- Dendrites are the processes of the neuron that receive signals from the previous neuron(s). A given neuron will normally have many dendrites to receive various types of input signals from various other neurons.
