The Neuron ** What is a Neuron? **  Neurons are the billions of cells that make up our brain, spinal cord, and nerves. In the brain alone there are up to 100 billion neurons. Neurons are constructed like most cells, however, they have a few specialized parts that make them different.

**What do they do?**

Neurons use chemical and electric signals to transmit and process information. These signals are called synapses. The synapses form connections with other neurons and build networks. **There are three specialized types of neurons**: Sensory Neurons  Motor Neurons and  Interneurons  **Sensory Neurons**  Sensory neruons are the neurons that respond to touch, sound, smell, light, and taste. These convert the external stimulation to something that your brain understands as feel, hear, see, taste, and smell. **Motor Neruons** These neurons are responsible for muscle movement through electric signals transmitted through our central nervous system, from our brain. **Interneurons** Interneurons connect other neurons within the same region to form networks.
