Introduction to neurons and glia. How the structure of a neuron allows it to receive and transmit information.

Neurons (or nerve cells) are specialized cells that transmit and receive electrical signals in the body. Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received …

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 …

These molecules are unconventional in that they are not stored in synaptic vesicles and may carry messages from the postsynaptic neuron to the presynaptic neuron. Also, rather than interacting with …

A neuron will always send the same size action potential. So how do we show that some information is more important or requires our attention right now? The answer lies in how often action potentials are …

A resting (non-signaling) neuron has a voltage across its membrane called the resting membrane potential, or simply the resting potential.

Learn about synapses, the connections between neurons in the nervous system, and how they transmit signals efficiently on Khan Academy.

What causes the hyperpolarization and depolarization of membrane potential, and how does change in membrane potential trigger graded and action potentials for the transmission of signals?

This video discusses synapses, where neurons communicate with target cells. It differentiates between two types of synapses: chemical and electrical. It also explains the role of the synaptic cleft, …
