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

Learn about the structure and function of neurons in the nervous system with this educational resource from Khan Academy.

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 …

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

Neurons are similar to other cells in that they have a cell body with a nucleus and organelles. However, they have a few extra features which allow them to be fantastic at transferring action potentials:

This video introduces the function and functional types of neurons. Neuron function involves processing and transmitting information. Key components include resting potential, action potentials, and the …

In neurons, however, the resting membrane potential is close but not identical to the K + equilibrium potential. Instead, under physiological conditions (conditions like those in the body), neuron resting …

Inhibitory signals work to cancel the signal. Every time an action potential is triggered in a neuron, that cell will release whatever types of neurotransmitter it has, because calcium cannot tell the difference …

Chemicals called neurotransmitters transfer information between two neurons separated by a gap. These chemicals pass the information from axon terminal of the first neuron to the dendritic tip of …
