Neuron types and their functionality


The nerve cell is the hub for all of the activity that occurs in the brain, and the connections between neurons create a living, dynamic framework for everything that we see, hear, taste, smell, touch and experience. How do neurons work? Nerve cells talk to each other via a complex system of electrical impulses and chemical signals. They are supported by another type of cell, called glia, which help these signals to transfer smoothly from one nerve to the next. Their work is so important that glia outnumber neurons in the brain and spinal cord. Types of Neurons Neurons fall into one of three types.Sensory neurons are responsible for relaying information from the senses—eyes, ears, nose, tongue and skin—to the brain to register sight, sound, smell, taste and touch.Motor neurons link the brain and spinal cord to the various muscles throughout the body, including those in our fingers and toes.Interneurons are intermediaries that bridge sensory or motor neurons to their neighbors.
