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.
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 structure and function of neurons, the specialized cells that transmit and receive electrical signals in the body. Watch a video and read the transcript, and join the conversation with other learners' questions and answers.
Anatomy of a nerve cell. Structural features of a motor neuron include the cell body, nerve fibres, and dendrites. With few exceptions, most neurons consist of three distinct regions, as shown in the diagram: (1) the cell body, or soma; (2) the nerve fibre, or axon; and (3) the receiving processes, or dendrites.
21 de dic. de 2023 · Learn about the four main parts of a neuron (cell body, dendrites, axon and axon terminals) and their roles in signal reception, integration and transmission. Explore the morphology, components and clinical relations of neurons with quizzes and videos.
