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 electric signal ...
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 ...
Learn about the basic units of the nervous system, neurons, and how they receive, process, and transmit information. Explore the anatomy, classes, and roles of neurons, and how they are organized into circuits.
Learn about the structure and function of neurons, the specialized cells that transmit and receive electrical signals in the body. Watch a video and read a transcript, and explore questions and answers from other learners.
20 de jul. de 2018 · Learn about the structure, function, and types of neurons, the cells that send and receive signals from your brain. Find out how neurons work, how they transmit electrical and chemical messages, and how they are involved in different functions and diseases.
As shown in Figure below, a neuron consists of three basic parts: the cell body, dendrites, and axon. The cell body contains the nucleus and other cell organelles. Dendrites extend from the cell body and receive nerve impulses from other neurons. The axon is a long extension
