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, which allow them to …

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.

This video provides an introduction to the cell types of the nervous system. Explore the world of neural cells, the building blocks of our nervous system. Uncover the roles and functions of neurons and glia, …

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.

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:

Cell differentiation is the process by which unspecialized cells are transformed into specialized cells. Specialized cells are those with specific structures and functions, such as nerve cells, muscle cells, …

In neurons, the cell enters a state of hyperpolarization immediately following the generation of an action potential. While hyperpolarized, the neuron is in a refractory period that lasts roughly 2 milliseconds, …

Nervous tissue is involved in sensing stimuli (external or internal cues). It is also responsible for processing and transmitting information. Nervous tissue is made up of nerve cells (neurons) and …

Introduction A single neuron, or nerve cell, can do a lot! It can maintain a resting potential —voltage across the membrane. It can fire nerve impulses, or action potentials. And it can carry out the …
