Neurons

In this chapter, we will learn Neurons, the neuron structure, neuron types, and neuron function.

What is a Neuron?        

The building blocks of the nervous system are neurons. It helps in receiving as well as transmitting signals to the different parts of the body. This process is carried out in both the electrical and physical forms. For facilitating the transmission of information, there are several types of neurons. The main function of the sensory neurons is to carry information from the sensory receptor cells, which are present throughout the body to the brain. The information between the different neurons in the body is transmitted by the interneurons.
