Within a nervous system, a neuron, neurone, or nerve cell is an electrically excitable cell that fires electric signals called action potentials across a neural network. Neurons communicate with other cells via synapses , which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the ...
Learn about the basic units of the nervous system, neurons, and how they receive, process, and communicate information. Explore the anatomy, classes, and roles of neurons, and how they are organized into circuits.
26 de abr. de 2021 · Learn what a nerve cell (neuron) is, how it works, and what are the three types of nerve cells in the human body. Find out how nerve cells form the nervous system and process information from the environment.
Nerve Cells. Despite the specific molecular, morphological, and functional features of any particular nerve cell type, the basic structure of neurons resembles that of other cells. Thus, each nerve cell has a cell body containing a nucleus, endoplasmic reticulum, ribosomes, Golgi apparatus, mitochondria, and other organelles that are essential ...
