You will also learn how the myelin sheath is formed at the end of this article. In addition, I will also show you different types of neuroglial cells and synapses under a light microscope with their proper identifying points. The main purpose is to introduce you to the structure of different types of neurons and their associated components under the light microscope. You will find different types of neurons (like unipolar, bipolar, multipolar, sensory) in the animal body, but the basic structure is almost similar. Here, I will provide details information and identifying points so that you may easily identify the neuron under a microscope.Ī neuron consists of a cell body that gives off a variable number of processes – axons and dendrites. Neurons may vary considerably in size, shape, and other features. and Purkinje cells (tree-like neurons located in the cerebellum).The structural and functional unit of the nervous system is the neuron that may easily observe under a light microscope. Some other unique neurons include basket cells (cortical nterneurons), double bouquet cells (inhibitory interneurons), spiny neurons (found in the striatum and cortex input receivers), chandelier neurons (inhibitory interneuron). Pyramidal neurons are found in the prefrontal cortex. These unique brain cells include the pyramidal neuron that has a cell body featuring a triangular pyramid shape. Thus, researchers explain that there could be a hundred or more types of neurons in the central nervous system. There are dozens of neurons that possess very unique structures. Interneurons connect one neuron to another: the long axons of projection interneuons link distant brain regions the shorter axons of local interneurons form smaller circuits between neighboring cells. Motor neurons carry signals from the brain and spinal cord to muscles. Sensory neurons collect information from sensory organs-from the eyes, nose, tongue and skin, for example. Researchers also categorize neurons by function. Local interneurons feature shorter axons that create small circuits between near brain cells or regions. Projection interneurons have long axons that join brain regions that are far from one another. Interneurons serves as connectors of neurons. On the other hand, motor neurons transmit signals from the brain to the spinal cord to the muscles to initiate action or response to stimuli. Sensory neurons are the neurons that harness information from the different sensory organs such as the eyes, nose, ears, tongue and skin. Neurons can also be classified based on their specific function. Each of them has a cell body, a long axon, and short dendrites. These neurons are the ones that are the closest to the model neuron that we usually see in neuron structure diagrams. Multipolar neurons are the dominating neurons in vertebrates in terms of number. Pseudo-unipolar neurons are responsible for the sense of touch, pain and pressure. The reason for this is that the single axon attached to the cell body proceeds to two opposite “poles” or directions – one towards the muscle, joints and skin, and the other towards the spinal cord. However, pseudo-unipolar neurons are actually variants of bipolar neurons. Pseudo-unipolar neurons resemble unipolar neurons because each of them has an axon, but no true dendrites. These bipolar neurons are usually found in sensory organs such as the eyes, nose and ears. These neurons are characterized by one primary projection that serves as both the axon and the dendrites.Īnother type of neurons is the bipolar neurons, each having an axon that transmits signals from the cell body going to the brain and the spinal cord, and dendrites that send signals from the body organs to the cell body. Unipolar neurons are the most common neurons in invertebrates. There are four major types of neurons based on their shape.
