A neuron or a nerve cell is a specialized cell that conveys electrochemical pulses throughout the body. They can carry information in one or two directions. Efferent neurons carry information from the brain to the tissue it's communicating with. This could be, for example, to skeletal muscle to stimulate movement. In contrast, afferent neurons carry information from various parts of the body to the brain. This feature allows you, for example, to feel the pain of a burn.
Neurons are quite diverse having a wide variety of branching patterns and differences in size. Some neurons are long, wide and myelinated while others are short, narrow and unmyelinated.
In the full version of this tutorial, we'll be looking at:
- the structures that make up a neuron that are visible in histological slides as well as different types of neurons based on shape. Specifically, we'll cover the main parts of neurons such as cell body, dendrites and axons and even dive into a bit more detail looking at structures within the cell bodies themselves such as the nucleus and the Nissl bodies.
- We'll also add a bit of detail into the axons and look at identifying myelinated and unmyelinated axons.
- Then we'll take a look at the different types of neurons including multipolar, bipolar, unipolar and pseudounipolar neurons.
- Finally, we'll have a look at a clinical condition and how it shows up on histological slide of nervous tissue.
