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 …

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, …

As you may remember from the article on neuron structure and function, synapses are usually formed between nerve terminals—axon terminals—on the sending neuron and the cell body or dendrites of …

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 …

Different classes of neurotransmitters, and different types of receptors they bind to.

Learn about depolarization, hyperpolarization, and action potentials in neurons with Khan Academy's comprehensive biology resources.

Explore how neurons process information through graded potentials. These transient changes in membrane potential occur in response to stimuli, influencing the neuron's behavior. Discover the role …

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