Here we have free and printable nerve cell diagrams for you who are learning about the nerve system especially in science class. All of the diagrams show you the detailed illustration of a neuron and its structure. So just explore the following diagrams and find yourself the one that is perfect for your study reference!
A neuron or nerve cell is an electrically excitable cell that receives, processes, and transmits information through electrical and chemical signals. These signals between neurons occur via specialized connections called synapses. Neurons can connect to each other to form neural pathways and neural circuits.
Neurons are the primary components of the central nervous system, which includes the brain and spinal cord, and of the peripheral nervous system, which comprises the autonomic nervous system and the somatic nervous system. You can take a look at the following nerve cell diagrams to know more about neurons.
Most cells are 20 micrometers in diameter, which is just a fraction of the width of a hair. A typical neuron consists of a cell body (soma), dendrites, and an axon. Dendrites are thin structures that arise from the cell body. An axon (also called a nerve fiber) is a special cellular extension (process) that arises from the cell body at a site called the axon hillock and travels for a distance, as far as 1 meter in humans or even more in other species.
Most neurons receive signals via the dendrites and send out signals down the axon. The diagrams that we provided above are nerve cell diagram. All of the diagrams are free and printable. Find more interesting and educative diagrams in our site by browsing up our category!
