10-Minute Neuroscience: Neurons

In this video, I cover all of the main parts of a neuron including the dendrites, cell body (soma), axon hillock, axon, and axon terminals (synaptic boutons). I describe how a signal travels from the dendrites of a neuron, down the axon, and to the axon terminals to communicate with another neuron through the release of neurotransmitters. I also describe ways of categorizing neurons based on structure (i.e., multipolar, bipolar, unipolar, and pseudo-unipolar) and function (i.e., motor, sensory, and interneurons).
