This video introduces the structure and structural types of neurons. Explore the structure of neurons, their types, and functions. Uncover the roles of dendrites, axons, and the soma. Learn about the axon hillock, axon terminals, and the myelin sheath.
Sometimes different parts of different cells perform other functions, but these tend to be where the neuron receives its signal. And we'll talk more about what it means to receive and transmit a signal in this video and probably in the next few.
In this article, we'll take a closer look at the synapse and the mechanisms neurons use to send signals across it. To get the most out of this article, you may want to learn about neuron structure and action potentials first.

Neuron function involves processing and transmitting information. Key components include resting potential, action potentials, and the roles of dendrites, axons, and neurotransmitters.
Action potentials (those electrical impulses that send signals around your body) are nothing more than a temporary shift (from negative to positive) in the neuron’s membrane potential caused by ions suddenly flowing in and out of the neuron.
Uncover the roles and functions of neurons and glia, and how they work together to regulate our body's functions. Discover the structure of the nervous system, divided into the central and peripheral systems, and the unique types of cells found in each. By Matt Jensen. Created by Matthew Barry Jensen.
Key points: A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential. The resting potential is determined by concentration gradients of ions across the membrane and by membrane permeability to each type of ion.
