What is a nerve?

In this tutorial, Matt from Kenhub explains what nerves are, their structure, and their function. Nerves are crucial components of the peripheral nervous system, connecting the body to the brain and spinal cord. Neurons, the cells within nerves, have axons and dendrites for sending and receiving impulses. The myelin sheath insulates these cells, and damage to it can affect impulse transmission. The video also covers the two types of nerves: cranial and spinal, detailing their roles and how they form nerve plexuses. Finally, viewers are encouraged to explore more resources on Kenhub.
