WN9: Nerve (video download)
Nerve cells, or neurons, come in many sizes and shapes. Here, Dr. Moran shows how they work together to form the wonderful wiring diagram that allows different parts of the human body to connect with and therefore interact with one another and the outside world. The half-hour video program begins with an introduction to the cytoarchitecture of neurons and their arrangement in the nervous system. Then, Dr. Moran shows beautiful light microscopic and electron microscopic images (along with helpful diagrams) that illustrate the ways in which neurons are constructed and organized. The program ends with a ten-minute practical examination (with answers) for student self-evaluation.
