These include nerve cells (or neurons) and glial cells (or glia). Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, …

Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received through the dendrites, travel to the cell body, and continue down the axon until they …

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 …

Neurons are composed of three main parts: dendrites, a cell body, and an axon. Signals are received through the dendrites, travel to the cell body, and continue down the axon until they …

For a cell’s membrane potential, the reference point is the outside of the cell. In most resting neurons, the potential difference across the membrane is about 30 to 90 mV (a mV is 1 / 1000 …

In this video I'm going to introduce the structure of the nervous system and the nervous system is divided into two main structural parts. The first is called the central nervous system.

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 …

Let me start by drawing a big axon terminal, so I'll just blow up that axon terminal and make it really big here in green, and then I'll just draw a target type of shape to represent the target …

Within a cell, action potentials are triggered at the cell body, travel down the axon, and end at the axon terminal. The axon terminal has vesicles filled with neurotransmitters ready to be …

Multicellular organisms are made up of various types of specialized cells, such as muscle, nerve, and skin cells. Each type of specialized cell has a unique structure and function.
