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.

An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, most organelles are also bound in a double …

This video shows how each cell’s unique structure helps it perform its job - biconcave Red Blood Cells (RBCs) built for oxygen transport, to the amoeboid White Blood Cells (WBCs) that chase pathogens, …

For example, nerve cells have branching structures that help relay signals, and many intestinal cells have hair-like extensions that help with absorbing nutrients.

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 …

Learn about cell biology and the different types of microscopes that allow us to observe cell structure and function.

A nerve cell is made up of the following parts, the dendrites, cell body (also called the soma), axon,and axon terminals. Some neuron cells in the brain are small, others, such as the ones that have axons …

And if we're in our carotid body or aortic body, you might have these special little blue cells that I've been drawing, our peripheral chemoreceptor cells. And specifically they have a name.
